iPhone 7 screen swap and strange touchscreen behavior
Hi everyone! Few weeks ago i swapped a broken screen with a, unfortunately, not-so-good new one, and i tested it (without immediately swapping home button) to see if it worked. Once i saw that it worked, i installed the home button on the new screen, trying to be as gentle as possible, and the phone gave me the touch id error message.
So i put the home button back in the original broken screen, but i found a weird behaviour: touchscreen was unresponsive (and home button wasn’t working anymore).
After some attempts, i noticed that if both screen connectors was connected, touchscreen was unresponsive (with or without home button), while if only the left screen connector was connected, touchscreen was working, but, again, no home button. As soon as I plug in the right screen connector, the touchscreen stops working.
In the new screen, touchscreen works with both screen connectors connected, but home button doesn’t work. Have any of you experienced something like this? What can be the cause?
Is this a good question?
