Digitizer not working - screen change
I cracked the screen on my iPhone 8 so ordered a replacement off eBay. It's not a genuine apple.
I switched the home button over, installed the screen, turned the phone on and the phone was acting really weird. It was really slow to boot, did not find mobile network signal it just displayed 'Searching' and then the screen just went black - the screen was actually quite responsive before this point though.
I decided to remove the replacement and fit my old one, genuine appl. Now the digitizer does not work - it was perfect before. The home button works fine, phone boots normally and connects to my mobile network.
Any idea what has gone wrong?
Ist dies eine gute Frage?
