Strange screen behaviour once clipped in place
So I have just rebuilt a rather bashed up iPhone 5s using one of those iPhone 6 mini housings and I have a strange problem.
When I test everything with the screen slightly lifted out of the chassis the touch screen works perfectly however when I clip the touch screen into the housing a couple of areas of the touch screen stop responding, in portrait mode the area around the "e" key on the pop up keyboard stops responding I get an r or w when attempting e, also the area where you swipe to power off goes unresponsive.
If I leave the phone powered on and then remove the screen then the behaviour stays the same until I sleep the phone and wake it, then the screen responds as normal.
I have fixed loads of phones in the past and just can't seem to figure this out!!
Do I have a dodgy screen or maybe some grounding problem when I close up the handset tightly??
Anyone got any ideas??
Thanks
Is this a good question?
