Android Custom ROMs Your Pc

If you like custom Android ROMs then get ready to celebrate, because you can already enjoy them on your computer natively. Thanks to a new community project, it is possible to install them as if they were any other operating system, such as Windows or Linux. Are you ready to enjoy them? We teach you how to install Android mobile ROM on PC with Android Generic Project.

Android Generic Project brings Android ROMs to your PC natively

We always say it, one of the coolest things about Android is how flexible it can be in everything. The level of customization is enormous, and with AOSP that is open source, the possibilities are practically endless.

Custom ROMs are the pinnacle of customization on Android, and there is something for everyone. However, until now these modified versions of Android were reserved for mobile devices only.

You could only install a Stock version of Android on your computer, or at most AOSP. How did you do it? Through an Android emulator, Android Studio, or more recently through Android x86. However, that will no longer be the case, because thanks to Android Generic Project you will be able to enjoy any custom ROM on your computer natively.

Android Generic Project brings Android ROMs

This initiative was introduced very recently, and it has the Bliss OS / BlissRoms team behind it. What did these guys do? Develop a suite of tools that allows you to easily port a custom Android ROM from ARM RISC architecture to x86 architecture.

What advantages does it have? That the consumption of resources will be less when installing it on the computer and that you will carry out a totally native installationAnything else? Yes, and the tool allows you to create an ISO file with custom ROMs to make installation much easier.

Android Generic Project uses Android x86 and also Google’s AOSP GSI as underlying basesThe result? You can now run Bliss OS on your computer, as well as Dirty Unicorns, Carbon, and more. In fact, every little bit more projects are added, and some famous ROMs such as LineageOS and Pixel Experience are already in the development queue. But how do you install the ROMs?

So you can install a custom Android ROM on your PC easily thanks to Android Generic Project

Yes, the title mentions Android Generic Project, but the reality is that this tool is only used by developers to port Android. What you will use to install an Android ROM on your PC is the final product. These are the steps you need to follow, which are actually very similar to Android x86, but please read to the end first:

Step 1:

Step 2:

  • Download Rufus on your computer from its official website. This tool will help you create a bootable USB key that will serve as an installer.

Step 3:

  • You can also burn the image to an optical drive like a DVD, and if you decide to do so, skip straight to step 10.

Step 4:

  • Install Rufus on your PC and open it.

Step 5:

  • Select the USB device that you will convert to a bootable drive.

Step 6:

  • In “Choosing start”, choose “Disk or ISO image”.

Next, press “Select” and add the ISO of the Android custom ROM that you have downloaded.

In the “Partition scheme” select GPT if your computer has UEFI or MBR if it has the classic BIOS (although a PC with UEFI should also read MBR).

Leave everything else as is and press “Start”.

Wait for the boot drive preparation process to finish, then close Rufus.

With the bootable USB key or bootable DVD ready and connected, reboot your computer.

Step 7:

  • Access the BIOS / UEFI of your motherboard.

Step 8:

  • Modify the boot order of the storage drives and put the drive first with the custom ROM installer.

Commit the changes and reboot. If you did everything right, the next time your computer boots it will try to boot from the bootable drive

Step 9:

  • Within the installer of your custom ROM, choose “advance options”

Step 10:

  • Select the option “… Install to specified hard disk”.

Step 11:

  • Choose the storage device and partition you want to install it on and confirm the action.

Be very careful what you do, especially if you are installing on a partition that has already been used. If you want to maintain two operating systems at the same time then the partitions of both systems must be different.

Step 12:

  • Wait for the installation process to finish and then select “reboot”.

Step 13:

  • Your computer will reboot and enter your Android custom ROM for the first time.

Step 14:

  • Complete the initial configuration of Android as on your mobile.

Step 15:

  • Enjoy your favorite custom ROM on your computer natively.

As you can see, it is a simple process, although there are some considerations. This installation process is the generic one used by Android X86 and is the one that all custom ROMs should use at least.

However, Android Generic Project allows you to modify many things, and perhaps a developer decides to change the process. Anyway, installing a custom ROM has never been a complex process, as long as you read and know what you’re doing, everything will be fine.

Are you ready yet?

A few days ago, Google announced that it is working on a solution so that all Android mobiles can detect earthquakes and notify each user of this operating system in a matter of seconds without the need for an app.

However, at the moment this function is being tested only in the state of California in the United States, so if you want to know when it will shake, take a look at the apps we bring for you.

Which app should you download to detect earthquakes

These are 5 of the most used and recognized applications worldwide for an earthquake. The effectiveness of each one may depend on what you really need, therefore, we will leave you these 5 options so that you are the one who decides which is the best app to detect earthquakes.

Earthquake Tracker is highly recommended by its users

This app has one of the best scores in the Play Store in its sector. 4.6 out of 5 possible points, after more than half a million downloads, demonstrate its great efficiency.

One of the things that characterize it the most is the availability of information almost in real-time. It offers a very complete information about the earthquake, epicenter, latitude, distance, depth, longitude, among other details.

Earthquakes Tracker

Terremoto Cruz Roja is one of the most complete apps of its kind

Terremoto Cruz Roja

This application will not only tell you when an earthquake has occurred in the area or areas that you have previously selected, but it will also offer you very valuable information on what you should do before, during, and after an earthquake. This information will be available even if you don’t have an internet connection.

You can earn stars through questionnaires about earthquakes, which will help you reinforce everything you need to know to be prepared for these types of phenomena.

American Red Cross Earthquake

Earthquake detector is the most downloaded app to detect earthquakes on the Play Store

With more than 6 million downloads on the Play Store, it has become the most popular app to detect earthquakes on Android. Its great receptivity among users is due to its large number of functions:

  • Detect earthquakes in real-time anywhere in the world.
  • Send alerts to all users with the app installed almost immediately.
  • It has a chat room to interact with other users.
  • If you get trapped and cannot notify anyone of your location, the app automatically sends SMS messages and emails to your trusted contact list.

You can also see a list of all earthquakes that occurred in the last hour, 7 days, or 30 days. Offers a paid option to remove the ads.

3D Earthquake

Regardless of the application, you want to download, it is important to always be alert and follow all the indications offered by the competent authorities.

Download Apps That Aren't on The Play Store

With a number of options, the Play Store is seen as the most suitable place to find any app. However, there are several apps that are not available in the store for Android devices.

Because they are in the testing or development phase, these applications are not available to the general public. However, it is possible to install them safely. Find out how to perform this process and secure sources to download apps.

Installing APKs Safely

In general, APK is the name given to apps downloaded from external sources other than the Play Store. Because of this,   Android devices will block the installation of any file that is not authorized by Google.

However, it is possible to manually change the configuration of the smartphone or tablet to use an application considered unknown. See the step by step:

  1. Go to “Settings”

  2. Access the “Apps and notifications” option

  3. Scroll down and click on “Advanced”

  4. Then, click on “Special app access”

  5. Enter the option “Install unknown apps”

  6. Search for the application you intend to use

  7. Then, enable the option key “Allow from this source”

Another way is to download the APK and, when the Android system sends a notification, perform the following procedure:

  1. Start downloading the desired app

  2. In the Android dialog, click on “Settings”

  3. Then, enable the “Allow access” option

  4. Click on “Download”

  5. After completing the download, open the file

  6. Go to “Options”

  7. Now, enable the option key “Allow from this source”

  8. Return to the previous screen and click “Install”

Where can I find secure apps outside the Play Store?

Fearful of downloading a malicious file, certain users are suspicious of apps from unknown sources. However, there are pages that offer free and secure content for Android. Meet some of them:

APKMirror

Managed by members of the North American website Android Police, APKMirror brings a series of apps in updated versions. Despite the simple layout, the files provided are from safe sources.

XDA Lads

Similar to the Play Store itself, XDA Lads is a source organized by XDA Developers. Totally free, when downloading the platform on the device, it offers several options of apps under development or in tests.

F-Droid

Also inspired by the Play Store, the F-Droid features several Open Source apps. When installing it, the user has access to several applications and receives notifications when there are new updates.

Recover Deleted SMS From Android

It has happened to you a few times that you have accidentally deleted a message and for this reason, we want to help you recover deleted SMS from your Android device. Best of all, with the latest smartphone models, you can also send and receive images and audio via SMS.

Often these messages remain forever in our inboxes and we do not bother to delete them. Can deleted messages be recovered? Text messages can be deleted for several reasons such as when you factory reset your phone or delete them accidentally or for a hundred, thousand other causes.

Nobody thinks about backing up messages until your messages are deleted from the inbox. Well, maybe in the future you will, but now, you want to know how to recover deleted messages. Because? Because right now you needed one of them.

In this guide, we will share some methods to recover deleted text messages from smartphones. If you often sync your smartphone with your Google account, your text messages have probably been saved to your Google account and you can easily retrieve them by syncing your smartphone with your Gmail account.

How to recover deleted SMS from Android

Method 1. Recover deleted Android SMS with your Google Account

How to recover deleted messages?

Step 1:

  • Restart the phone by pressing the Home, Volume Down, and Power buttons to enter recovery mode.

Step 2:

  • Use the volume up and volume down buttons to scroll through the options, choose “Factory reset/wipe” by pressing the Home button.

Step 3:

  • Restart your Android phone and on the boot screen, it will ask you to log into your Gmail account.

Step 4:

  • Enter your Gmail account credentials and synchronize your smartphone with it.

Done! You will now be able to recover deleted SMS from your phone. This only works if you have backed up the messages on your Gmail account before the messages were deleted. An Internet connection is required to restore messages.

Method 2. Recover deleted SMS from mobile using a data recovery tool

The method we have talked about is not very reliable for retrieving messages. The best way to recover deleted messages from your smartphone is to rely on data recovery software like Androidphonesoft.

It is a flawless and amazing program that can not only recover text messages from your Android phone but also music, videos, pictures, contacts, notes, and other information that has been deleted.

It is possible to recover deleted files and documents on almost all Android smartphone models including Samsung, LG, Motorola, Google, OnePlus, etc. Below we will show you how to recover deleted Android SMS.

Please note that this program works with Android phones and all other smartphone models. Furthermore, it is possible to recover other types of data as well as contacts, pictures, music, videos, notes, WhatsApp, etc.

Over the years, there has been a long discussion about smartphone batteries, but even today there are doubts about the best ways to load equipment and what causes affect battery degradation or not, and which of the most common recommendations really help save energy or which ones are simple myths.

Fortunately, little by little, we have increasingly clear information about the energy source that gives life to our terminals.

One of the most common procedures that probably more than one of you has heard of at some point is battery calibration. But is this process really necessary? And if so, What are the steps to follow to calibrate the smartphone battery?

In this guide, our intention is to put an end to all doubts on the subject, and thus eliminate the myths that exist about whether battery calibration is necessary, or whether it can be counterproductive and harmful.

What is the use of calibrating the battery and how often does the user need to do this?

Virtually all smartphones launched on the market in the past two decades incorporate lithium-ion batteries. However, it was in 1990, when this technology was developed, although it went through different changes and evolutions over the years, it started to be used in devices present on the market in a generalized way.

In the case of smartphones, despite using batteries based on the same technology, experts in the field like BatteryUnivesity consider that these devices integrate “Smart batteries”, that are somehow able to communicate with the device itself.

The problem is that when designing and building energy sources, engineers mistakenly assume that the batteries will maintain optimal functioning throughout their useful life. That, unfortunately, it’s not like this and, in fact, battery degradation is impossible to avoid and, in most cases, irreversible process.

Battery on Android

Degradation and the passage of time affect not only the battery life itself but can also affect the accuracy with which the remaining level is measured.

This makes it a very common problem on modern smartphones, the operating system indicates a wrong battery level, which can end up being translated into other more serious problems like the smartphone shutting down when there is still 20% of battery.

What really happens in the latter case is that the actual battery level does not match that indicated by the operating system, since the passage of time has accentuated the margin of error to the point that the software does not have an accurate battery measurement.

This is partly the fault of the user, since, in general, “smart batteries” are calibrated autonomously through complete and punctual charge and discharge cycles, but many users rarely perform this process – probably because among the many claims on batteries is the one that says that completely discharging the battery can damage it. It is precisely in these cases that the need to calibrate the batteries manually.

Yet, What happens if the calibration is not performed periodically? Although the operation of the battery itself should not be affected – at least not directly – nor should it be detrimental to cell integrity, experts say that a poorly calibrated battery means that the readings taken by the operating system will be less accurate and therefore less reliable.

With that in mind, the next question that naturally arises is how often should we calibrate the smartphone battery. Resorting again to BatteryUnivesity, the frequency of a calibration process every 3 months of use or every 40 partial load cycles it may be a good recommendation.

How to calibrate your Android smartphone battery

Drums

Now yes, it’s time to calibrate your smartphone battery. Although on Google Play there are applications designed to perform this process automatically, in fact, performing the calibration is much easier than it looks, and they do not need external help or specific tools.

To calibrate the battery of a smartphone, whether Android or based on any other platform, just follow these steps:

  1. Discharge the smartphone battery until the “Battery low” warning appears – according to BatteryUnivesity, it is not necessary to drain the battery until the phone hangs up.
  2. Fully charge the battery.

That’s all. No leaving the phone off and without a battery for several hours, or connected to the charger once it reaches 100% or any other myth related to the battery calibration process that has been flooding the network for years.

When performing these two simple steps once every several months, we must end the main consequence of an out-of-calibrated battery, which is nothing more than erroneous readings of the remaining energy level by the operating system.

If what the user was looking for are ways to extend the smartphone’s autonomy to the maximum as if it were new again, I fear that your fight is against natural degradation. And faced with this problem, there is no such simple solution.

Other tips for taking care of your Android battery

Smart Battery on Android P DP2

Although degradation is an impossible process to avoid, there are recommendations that can serve to take care of the smartphone battery and delay this process. Some of the most recommended procedures, which we should all perform, are the following:

  • Avoid extreme temperatures:

above all the heat. Lithium-ion batteries are sensitive to both temperature and sudden changes in temperature. It is best to keep the battery – and therefore the smartphone – at a temperature around 15 degrees, whenever possible.

  • Do not do full loads:

As I said before, draining the battery completely can negatively affect performance. In general, it is best to keep the battery level between 30 and 80%.

  • Don’t worry about the first charge:

As soon as you receive your smartphone and take it out of the box, enjoy it. When it’s time to charge it, turn it on without worrying whether it’s better to completely drain the battery or let it charge for several hours. This is a myth inherited from nickel batteries, which required some care during the first charge.

  • Always use the original charger:

and when it is not possible, at least use a compatible and certified one, and under no circumstances use a charger from an untrusted brand.

  • If you won’t be using your smartphone for a while:

In that case, it is better to keep the battery level at around 40%. It is not recommended to fully charge the battery before leaving the device unused for long periods of time.

  • Charge your smartphone overnight, yes or no?

leaving aside the fact that it is better to perform partial charges, not complete ones, the truth is that leaving the phone plugged in at night is not dangerous. Intelligent lithium-ion batteries deactivate the charge flow once completed.

The world of apps for Android smartphones passes from the files with apk extension. Let’s go deeper into this topic and try to get to know this sector better with useful information also on the risks and opportunities that these files offer.

We got used to Windows Exe files, jpg files for images, pdf files for documents, and many others; now is the time to understand and know better what are apk files, how to install them, and what issues (because there are) about safety.

If we want to summarize, we can say that these are the application files that we have on our Android smartphones, but with which we often don’t even get in direct contact because we manage all the app from the Google Play Store.

In reality that is not the only channel, even if the only official one, with which to install apps on our phone with the Android operating system. So let’s try to clarify.

What are apk files

What are .apk files

As the online encyclopedia Wikipedia reports, the apk file is “used for the distribution and installation of supplied components on the Android mobile platform“.

If to install a program on Windows you need to start a file with a .exe extension, to do the same thing on Android (which is an operating system other than Windows) you need to start the .apk file extension.

How to install on Android smartphones

How to install apk files

To install an apk file of an application, simply open that file, follow the settings on the screen and in a few clicks finish the procedure.

Difficulties arise in find apk files, send them to your smartphone, find them in the memory of our phone and overcome the security limits that Android places, why we will see it shortly, in the installation of these files.

To find apk files you can access sites and online search engines dedicated exclusively to these files, while to send them to your smartphone just use the Bluetooth connection (to transfer them from one device to another), or send them by email from your PC or, again, transfer them via cable always from the PC. In all cases it is important to know where they are saved (the downloaded ones are automatically destined for a folder called Downloads)

in order to take them and start them. The easiest way to do this is the use of File Managers which allow you to move within the smartphone memory as if we were among the folders of our pc. Alternatively, you can search for the file directly from your smartphone, this facilitates the download and immediately makes the file available for installation.

Very often once you get there install apk files our Android smartphone blocks the operation by remembering the security risk of installing applications downloaded from external sources. To deactivate the block, even temporarily (the time to install the apk and then reactivate it) you need to follow a simple procedure.

A procedure that varies according to the Android version present on the smartphone. Basically there is a procedure valid for all versions of Android until 7 and one for the subsequent ones (hence from Android 8 Oreo, Android 9 Pie and Android 10 on). Let’s see them both:

Install apk from unknown sources for devices up to Android 7

  • access the Settings of the telephone;
  • press on the item Safety;
  • locate the item Unknown origins;
  • activate the flag.

From this moment when you open an apk file the procedure continues normally and you are able to complete the installation process. Once the installation is finished, simply disable the flag on the item Unknown origins to reset the security lock. The procedure may vary slightly depending on the brand of your smartphone.

Install apk from unknown sources for devices from Android 8 and above

The procedure has been changed compared to previous versions of Android and involves the following steps:

  • access the menu Settings of the smartphone;
  • select the menu Apps and notifications;
  • press on advanced;
  • to select Special app access;
  • press on Install unknown apps.

At this point, it is necessary to select the application you want to install (for which to grant authorization for installation from unknown sources) and continue with the procedure until the installation is complete. Here too there may be small differences in the path to follow.

Why apk and not Google Play Store

Google Play Store and apk files

Before facing the thorny security issue of files with apk extension it is appropriate to wonder why a user should prefer this way, evidently more complex and articulated than to start the Google Play Store, search for the desired term, select the app and install it. The reasons, of course, are there and can also be very interesting.

Basically you need to know that the world of smartphone apps is much wider and more varied than we think. The apps are not only those present on the Google Play Store (as they seem, and they are, to be many).

Google requires certain standards to insert an application in a store but nothing prevents a developer from creating an app and distributing it outside the official Google store.

And so, in fact, it happens with hundreds of apps that are o revised or expanded versions apps already known (as in the case of WhatsApp Plus), programs not available in your country (not all existing apps are downloadable in Italy) or applications that offer services (such as downloading videos from YouTube or Facebook in a few clicks) for which there is no application on the Play Store that performs the same operations.

Although the Google Play Store offers certainly remarkable visibility, it is equally true that for developers having to subject to certain limits o having to pay the cost of distributing your work (a subscription costs about € 25 although there are no limits to the number of apps that can be presented to be included in the store) can be a problem; here is the choice of spreading your apk file in other ways, also taking some risks. Let’s see why.

Security issue: you have to be careful

Security apk files

As we have seen our smartphone Android blocks installation by default of apk files as to install applications you can take advantage of the official channel, certainly more secure.

The question of security revolves around the fact that, since there is no guarantee (which the presence on the Google Play Store provides), apk files can hide viruses or malware which can cause problems.

In itself, however, very often we may not even realize it, as the app works quietly, and apparently ours too device works regularly (except in some cases in which a reduction in performance and autonomy is evident).

Android apps often come from unknown sources they are real Trojan horses with which hackers and attackers can enter our smartphone and have, in a more or less uncontrolled way, free access to files, resources, images, videos, and personal data.

In summary, it can be concluded that installing .apk files offers interesting opportunities but which are not without risk. You have to basically understand if it is worth taking this risk or, alternatively, be sure that that apk file is really safe and therefore free from any kind of security threat of our smartphone.

 ringtone

Another small tutorial on how to change the ringtone that comes by default on your smartphone. There are a lot of ringing tones that we hear out there, those are the things that we can use to personalize our experience with mobile devices and also reveal a little bit of our personality.

Whether fans of Rock, Pop, Jazz, or even an alternative or sometimes we want to have that specific touch for our annoying boss or our girlfriend, this is something that the Android system allows with some simplicity. So let’s get started.

Prerequisites:

Obviously we will need a smartphone to start, and of course the audio file of the song we want to choose.

More personal than ever:

There are also several applications that allow you to download the ringtone or ringtone you want, the application Zedge is one of them, likewise lets you directly within the application define the ringtone as the main ringtone.

But let’s do it the old, more conventional way.

  1. Open the applications drawer and click on Settings
  2. In the settings, look for the “sounds and vibration” option, and select
  3. Select the Ringtone option
  4. Choose the ringtone you would like to use from the existing options, or select any mp3 file you have in your smartphone’s memory.

And now you can show a little more of your personality with the new touch, so that everyone knows what kind of person they are, at least when they receive a call.

But take it easy, then, and if you want a personalized touch for that special someone.

  1. Open the applications drawer and click on your contact list
  2. Search for the contact you want to add a specific ringtone to and select
  3. In the upper right corner, choose more options
  4. Select the Set Ringtone option.
  5. And in the same way, choose the touch you would like to use.

And then everything is ready, do you already use the ringtones that are defined by default or do you use something with more style? Leave your answer in the comments.

IP ratings refer to the rating of International Protection Brands which is given after a series of tests performed to see how much dust and water can get into the phone and under what circumstances. Each number and letter represents a different level of protection, the full list of which follows below.

How-waterproof-is-my-phone-What-do-IP-certifications-mean

Tougher phones

Manufacturers are making Android phones more robust than they used to be. It is a great selling point. Phones Samsung, Huawei, LG, Motorola, and even Google now come with some degree of resistance to water and dust. What these numbers represent can be important or even a deciding factor when spending money on a new phone.

You will usually see “robustness” described with an IP rating or a MIL-STD rating or both. These are patterns that determine how something is resistant to the elements – things like water resistance, shock (electrical and physical), temperature, air pressure, and a host of other things that can damage your phone.

Classifications and certifications were developed long before the invention of smartphones – they cover things like valves and electrical boxes. And now they apply to phones and not just those that are built like tanks. We will detail each classification to know what they really mean.

Ingress protection / International Protection

Entry protection refers to the ability of a product to prevent foreign objects – specifically particles of liquid and dust – from entering. And although we generally think that the term IP means Ingress Protection, actually means International Protection, as an international protection certification.

The IP Code is designated by the initial IP, followed by two digits and possibly a letter. Most letter designations are something we will never find in small portable electronic devices; they are used in devices that can withstand high-pressure jets and high flow jets, such as a spray nozzle for washing cars.

Consumer electronics are not manufactured to withstand these conditions, but IP ratings cover more than consumer electronics, so they are included in IP certification.

Each digit represents a resistance rating. The first number represents the level of protection from solid particles (dust). The second number means protection from the ingress of liquids. A manufacturer does not need to test both, but if he does not, the number will be replaced by an X, we can see something like IPX7 or IP6X. see how the numbers pile up.

Solid particle protection

Solid waste IP number How effective is it?
IP number description
0 Not protected in any way from particles of any size.
1 Protected against particles larger than 50 mm
2 Protected against particles larger than 12.5 mm
3 Protected against particles larger than 2.5 mm
4 Protected against particles larger than 1 mm
5 Protected against Dust: Dust cannot get in enough to affect normal operation.
6 Total protection against dust: Dust cannot enter, even in a vacuum.

Liquid inlet protection

Net IP number How effective is it?
IP number description
0 It is not protected at all.
1 Protected against dripping water.
2 Protected against water drops when tilted to an angle of 15 degrees from its normal position.
3 Protected against water spray when tilted to an angle of 60 degrees from its normal position.
4 Protected against splashing water at any angle.
5 Protected against spray water of 6.3 mm at 12.5 liters/minute and 30 kPa (pressure) at three meters distance for three minutes.
6 Protected against water spray from a 12.5 mm nozzle at 100 liters/minute and 100 kPa (pressure) at three meters distance for three minutes.
6K Protected against water spray from a 6.3 mm nozzle at 75 liters/minute and at 1,000 kPa (pressure) at three meters distance for three minutes.
(1,000 kPa is a standard amount of water pressure).
7 Protected against immersion in water up to one meter at normal pressure for 30 minutes.
8 Protected against water immersion at one meter or more in the specifications detailed by the manufacturer.
9X Protection against water spray in high-pressure jets at high temperatures.
Water flows from 14 to 16 liters/minute
Water pressure from 80 to 100 bar (up to 1,451 Psi)
80-degree water temperature
Distance from 0.10 to 0.15 meters.

In addition, the IP Code has letter designations for additional protection. Like the K classification, we’ll never see that on a phone, but since we’re talking about the topic, here’s all the information:

Additional protection designation

Letter code What does it mean
Code description
f Oil resistant
H High voltage protection
M Protection against movement
s Total motion protection
W Weather-resistant

Yes, the “f” is not capitalized, and “weather resistant” says nothing. We didn’t write the specification, I don’t know why they call it that, and as I said, this type of certification is not applicable to phones.

Do we already know everything we need?

When you buy a phone that has an IP68 rating, you can put it in a vacuum and the dust won’t get in, or let it be immersed in more than a meter of water forever, right? Do not.

The dust protection rating leaves zero room for maneuver. IP68 means dust under any conditions that a human being may be in. The liquid inlet protection 8 is “specified by the manufacturer” and you will need to know what that specification is. Samsung, for example, says the certification covers submersion up to 1.5mts for up to 30 minutes.

Can we go play with the phone to the pool without risk?

It is not so. Samsung also says your device is not impervious to water damage in any situation, which is a total contradiction. But it is not the only one – almost all electronic devices include text in the warranty or in the user manual that says that the warranty does not cover against water damage, even if the device in question is classified with an IP rating.

This is because the devices used for testing and certification were able to withstand the invasion of dust under any circumstances up to and including vacuum, and immersion in water at a depth of 1.5 m for half an hour. Your phone may not survive.

The certification feature cannot test all phones. IP certification is additional protection and not an absolute certainty that the equipment can be immersed without damage.

MIL-STD certification

This is a US military standard that specifies how something will behave against the environment during its lifetime. Android phones, watches and other electronics can carry MIL-STD 810G certification, which means that they were tested in a laboratory under conditions that simulate a gigantic list of environmental variables and continued to work. Some of the things that are tested include extreme temperatures, altitude, thermal shock, fungal entry, and frozen solids. This one an exhaustive list.

If your phone model passed all the tests, does that mean you are free to do what you want?

Do not.

This certification seems to do little actually felt. To begin with, testing procedures clearly indicate that a manufacturer only needs to test simulated environments, which does not mean that it will withstand a real scenario. If that’s not enough to make you suspicious, the fact that the tester can decide how he wants to do the simulation says it all.

Dr. Conrad H. Blickenstorfer, Ph.D. explains perfectly when discussing MIL-SPEC standards for laptops.

MIL-STD-810G does not require standards or set minimum targets for the various tests; for the most part, it simply describes how the test should be conducted. This leaves considerable room for interpretation and it is therefore important that rugged notebook manufacturers provide detailed information on which tests were conducted, how exactly they were conducted, what the results were and what these results really mean. The claim that a product is “certified by MIL-STD-810G” is not sufficient, and prospective customers should ask for more details.

To say that a device is MIL-STD 810G certified without providing a copy of the test parameters and the results mean the same thing as “this smartphone is fast” or “it has an excellent camera”. Never think that your electronic device will withstand these types of conditions unless you have seen the parameters and test results.

Viewing IP ratings and military-grade certification assessments on a phone is usually a good thing. Not all devices will pass all real-life tests, but there is a significant likelihood of going well.

Having an IP certified phone is great protection against accidents like spilling water or using it in a dusty environment, and a MIL-STD 810G certified phone will have more protection than one without. Just be aware that taking your smartphone to dive or in more aggressive activities can go wrong and the guarantee will not save you.

The IMEI of our smartphone is a 15-digit code used to identify the device and that they must know to do things as important as lock the terminal after being lost or stolen.

With Google’s Find My Device

The location function of Google devices can be a great lifesaver if your phone is lost or stolen. In addition to being able to reproduce a sound that will facilitate the location of the smartphone or indicate the exact point where it is located, if it is connected with GPS enabled, the Find My Device tool also shows the phone’s IMEI, even if they don’t have it with you.

In that case, they must be logged in with the Google account on the referred terminal for the tool to work. If they’ve done that, they’re going to Find My Device, Sign in with the same Google Account you use on your smartphone, and on the left, you’ll see the list of devices linked to that account.

Find your smartphone and click on the Information button that appears on the right, represented by an I icon surrounded by a circle. This will show a small window with device information, IMEI number included. This way, they will be able to see the IMEI, even if they don’t have a smartphone with you.

IMEI on Find my Google device

As you can see, there are several methods to find out the IMEI of your Smartphone, whether it is close or not.

The gallery displays all the photos that are in folders on the smartphone. Each folder appears as an album.

The Android photo gallery is not one of the most discreet applications. The gallery displays all the photos that are in folders on the smartphone.

Each folder appears as an album. There are several ways to hide photos in the Android gallery. In this tutorial, we show you the fastest way to protect certain photos from prying eyes.

Hide android photo

A simple way to hide photos on your Android smartphone is to use an application from Play Store. Because there are several that do this task well. They function as safes in which the user can place photos or videos.

To access these files, they must necessarily go through the application, which must be protected by a password. THE Vault application does this for example, and very well.

Another option is to simply block the Gallery through a solution that blocks access to applications on Android. But this approach is not the right one in all cases.

How to hide a photo album on Android

If you want to hide photos simply without installing a third-party application and there are two solutions. The first is to create a .nomedia file in a directory containing images that the user does not want to see in the gallery.

To do this, they need a good file manager. And since we are talking about how to hide photos without installing an application, you can simply use the standard file manager on your Android smartphone.

  • Create a special folder with the file manager.
  • Move all the photos you don’t want to see in the gallery to this folder.
  • Then enter the directory and create the .nomedia file inside.

We emphasize that the period (.) Must be placed before the name. This file is empty, but the system will interpret it in a very specific way: it forces you to hide the photos located in the folder in which it is located.

How to hide a photo or album on Android without using an application 1

No application, including the Gallery, can, therefore, display the multimedia files in that folder. However, they will be visible in the file manager. Therefore, it is preferable to create the directory in a location that is not too exposed.

The second method to hide your photos

The second technique for hiding photos on Android without a third-party application is to hide the directory that contains the images. The folder itself will not be visible in the file manager unless the option Show hidden folders is enabled.

To hide a folder and, therefore, the photos and other content contained therein, simply precede it with a period (.). Example “.My images”. And ready.
