My Galaxy s3 is cracked ( the glass hasnt cracked so im assuming its the digitizer/lcd) when i look at the phone at an angle i see black lines along the screen. When I first realised it, the screen was predominantly black with blurs of other dark colours. It eventually became all black over the course of the day but it would still turn on. Now it does not turn on or charge. Will buying a new lcd and digitizer fix it?
