A few months ago I dropped my SK17 and the screen cracked. Despite being cracked and with pieces falling apart, the screen worked perfectly. Yesterday I dropped my phone again and it stopped responding to touch. The screen looks exactly as before falling but it stopped responding to touch. The soft keys still work. Will replacing the screen solve the problem? I already flashed my phone to an original firmware but it solved nothing. I don't mind replacing the screen and spending a few bucks to get my phone working but I'd like to be sure if the problem's in the lcd.
