Nokia Lumia 920 vs. Lumia 925, is there much difference?

Just introduced the new flagship of the company, the new Nokia Lumia 925 , and many wonder if there are large differences with its predecessor, the Nokia Lumia 920 . It appears that the eye itself, ie, its casing is now aluminum, in addition to its size and weight, which seemed an impediment to telecom operators will give the approval.

Apart from this, the Nokia Lumia 925 changes a couple of features on the hardware, such as screen and camera, which seems to have improved over the Nokia Lumia 920 , otherwise it seems that has changed.

It seems that one who has a Nokia Lumia 920 will not see a great need to change the new Nokia Lumia 925 , or so it seems to us.
