So, I’ve fixed many iPhone screens and I’ve never had this issue before First, after the screen had been assembled onto the device, I boot it up by plugging the charger in as I always do. The screen seemed to be working fine as far as touch functions are concerned. I allowed it to charge for awhile before giving it back to the customer So, before I went to work, I turned it off. When I came home from work, I turned the phone back on to double check that everything was still functioning properly. This is where the issues began, the touch did not work and it had a “phone is disabled for 5 mins” message on the home screen. I unplugged and re plugged the battery and flex cables to make sure I had good connections all around. Everything seemed to be fitting fine. So, when I turned the phone back on.. viola! The touch is back working….turn it off…touch not working. Repeat the previous procedure of unplugging and replugging the battery, turn phone in, and touch is back working It’s currently working but I’m scared to turn it off again. I’ve never had this issue. What do I do?
the “Touch IC” is part of the 6s screen unlike the 6 and 6 plus where it is part of the logic board. It sounds like you have a faulty screen (digitizer) assembly. Probably “Ghost touch” causing phone disabled for 5 min as it is randomly touching digits for pass code and being incorrect, locks you out. I would try the old screen if working and available to test with or another screen if available. If you have it up and running, do a complete data backup just in case while it is working (You may end up with a software issue and have to restore it and would be nice to have saved Data).
