Just a few hours ago, it became known that there was a minor update to the two most popular 4G smartphones Galaxy S3 and Galaxy Note 2. You can get the update by OTA or via Kies.
Firmware I9305XXBME3 except that fixes some bugs and still runs on Android 4.1.2. If you do not want to wait, you can get the update and install it manually – at our site there are already several ways to install the firmware on the Galaxy S3.
The second update is for Galaxy Note 2 4G. It is available on FOTA and has a number N7105XXDMG1. But this firmware is still version of Android 4.1.2. Looks are not destined to smartphones that run on Android 4.2.2, because it really is to get Android 4.3.
