I have replaced my faulty Iphone screen twice with TWO separate screens. The first screen had classic signs of faulty parts(White and black lines up and down the screen, and some checker patterns) NOW this second screen is working perfectly fine, NO LINES NO CHECKERS. The phone looks like new, YET I still have no touchscreen function. SIRI works and responds. Should I try a hard reset to resolve this issue? Soft resets have done nothing so far. I havent been wanting to do a hard reset cuz I don’t know if my phone is actually backing up on my PC even though it says that it is. Itunes does recognize it as my phone as well, so its not like I have to force it to sync. THANK YOU
My first guess would be the digitiser cable isn’t down properly. Make sure you clip it in nicely, if it doesn’t feel right then it probably isn’t. If that doesn’t work try holding the screen at about 45 degrees or so and see if you get any feedback at all from the digitiser, if it responds a little but jittery, then it could be a pinch in the cable when you closed the screen down. Otherwise try a new screen if you can as it could just be a faulty digitiser.
Thanks for the responses, as of right now I have sent back the second screen and am awaiting more info. I just find it very hard to keep getting tech that “doesn’t work” or is “faulty” but thank you for all the information. I’m just going to take better care of things as far as my tech goes. Will fill in when I have more info.
Update: I have received a third replacement screen and once AGAIN I have no touch screen function… I am feeling my phone is broken -_-
