A friend of mine broke the screen to his Samsung Core Prime G360V and I tried to fix it for him I replaced the Digitizer and the lcd screen and now intermittently about 1 inch of the screen is non responsive. When you first turn the phone on and you have to enter his pin to unlock it the 1 2 and 3 won't respond then after a minute or so it will like it was hung up is it the digitizer or the LCD that is defective? I can get a refund on both if I send it back now but I dont want to send back the wrong part. Please help us.
