Do I need to buy digitizer or the LCD
My lumia 820 fell a couple of weeks ago and got its screen cracked. The strange thing is, the outside screen was fine, but a single crack happened in the inside. Now the display is not working. I opened the phone and noticed that the inside of the digitizer was broken. So i am a bit confused, is it because the digitizer was broken from the inside that the display is not working. Or is it the LCD (which doesn't happen to have any scratches on it).
