I replace the display of iPhone5 but the touch not function correct
I changed the display of my iPhone5 following all the instructions of the guide , at the end of the iPhone is turned on and seemed to work well , the touch response was good , then during use and opening the app I've seen that sometimes the touch it is as if it were not calibrated . It happens that the screen stops for a few seconds does not activate the touch but then at the end you unlock and it works all right . I also went to a service center that made me a diagnostic and saw that the display had been mounted properly and probably the Case Study was due to defective display. Can this happen ?
