Hello, Recently I replaced the lcd + digitizer on an iPhone 7. After a test everything works, but after a while the iPhone locks up while using: the screen freezes (still showing everything) but the digitizer doesn’t seem to be reacting. The only thing that works is a soft reset ( power down + wake). After reboot the iPhone works again. But the problem returns so a soft reset is needed again. First time I’m having this issue. Is this just a faulty screen?
Hello! Does the device seem hot?
Classic symptom of a faulty screen, try another one! Best of luck with the repair :)
