My iPhone is sitting at the activation screen. I am able to swipe to unlock and select my country. When I press the arrow in the top right to go to the next page, it doesn’t respond. I’ve tried pushing with some force but the touch on that specific spot does not respond. To add to further confusion I powered the phone off and swiped across the top and it registered fine. Has anyone had a similar issue and found a fix? Any help is greatly appreciated.
Cody, since you already tested the display/touch on a separate phone, there are two things I would check on. One is the touchscreen connector. Make sure it is properly seated and make sure the pins on the inside of the connector are not bend or broken. The other issue could be the touch screen IC, you may want to try a reflow, or if you have the tools, reball the chip. Hope this helps, good luck.
If it is the same spot or spots that are unresponsive then you might have a bad digitizer. You can use the guide here to open it up and reseat the digitizer cable and make sure its making good connection…. Otherwise, I would go with replacing the screen assembly. Hope This Helps!
