The phone comes with a 3.7 inch screen with 800 x 480 pixel resolution. The display is bright and images appear really nice and text is also sharp. In fact this screen is one of the best that you can get in this range.
It is covered with Gorilla glass which protects it from scratches and probably a few falls (we didn't test that and advise that you don't either).
Even in terms of response the screen is butter smooth and registers each touch as and when it happens, without delay.
