I have a samsung SPH-A640 cell phone. The screen is blank and I can't use any of the functions. I can still call out and receive calls.I have the same problem, I have the same model, the samsung SPH-a640, and today I acidentally stepped on the screen really hard, and all there is is a white screen with pixels. It still works perfectly, but I cannot see anything because that image is always there. Please Help! :)
