Hi, I currently have a Samsung Galaxy Ace 2 i8160 which had a cracked LCD screen. I purchased a replacement and a spare digitizer (Just in case) and installed it. The LCD works fine but the old digitizer stopped working. I figured I must have broken it taking it out, which is why I got the spare one. However, that doesn't work either. I have checked the ribbon connection, made sure the white lines were aligned properly, even tried un-aligning them, but nothing. I have no expertise in this area so be gentle with me. Any help would be gratefully received.
