Touch screen problems after screen replacement
I have been replacing screens on iphones for quite some time now. The iphone 5c and 5s are a different animal. The last few that I've done have me puzzled. It seems as if once I put them back together, the touch response is all over the place. After a hard reset they work for a while and then when you go to touch an icon, another app may open and not the one you touched. I've swapped out the screen with a different one and it does the same thing. Is there some sort of calibration to do on these new phones? It's getting to the point that I'm going to turn down customers that bring them in to be fixed.
