iPhone 7 plus not working
I just updated my Iphone 7 plus to the new ios 11, after the update phone isnt responding as it should, touchscreen is taking years in responding to swipes, same for the apps take !&&* lot of a time in opening up, Sound isnt working either not in calls, ringtones, games or music etc.
I reverted back to IOS 10.3 and its all fine but not on ios 11
I had my phone's screen repaired (aftermarket) because of the damage and I read somewhere its because of that the new ios isnt working
I will be very glad for any help
plus I live in Pakistan and to my knowledge there is no apple genius bar here.
