Hi! Frozen+Touch keys+Power Button Model: Galaxy S2 - SGH-I777 AT&T American Version Today in the morning, after already had used my phone it stopped working. The screen was completly black and I knew it was ON because I could hear the sound of up and down buttom ringer volume. I restarted and all the keys - menu, back, keyboard - were a mess and showing like I had used shift to change the letter. All the time when the lights are gone, I have to switch it ON again cause it shutted down. Even putting on and off the battery for many times the problem was not solved. I searched about on the internet to understand what was happening but I did not find nothing like my problem. So I decided to reboot firmware going back to the same 2,3,4! Everything OK, I have done with Odin, etc... Even with the phone cleared the problem still remain, no keys menu, back and keyboard delay like I had used shift to change the letter and when the lights are gone, I have to switch it ON again cause it shutted down. What can it be? What should I do? Since now I appreciate, Bruno.
