"There are numerous reports of aftermarket replacement screens failing after upgrading to iOS 11. At this point there is not much that can be done other than going back to iOS 10.3.3. You can check my profile for a brief blog post I did.
EDIT
Update 2017/10/11 - Apple just released iOS version 11.0.3 and it claims to address the Touch Failure on aftermarket screens. For those of you that have been waiting for an official fix, it appears to be here. Make sure to comment below if this update solves your problem.
Update 2017/10/31 - Apple has just released iOS 11.1. Check out the details here."
iPhone 7 copy screen not working with ios 11 yes why???? cuz 3rd party replacement screen need to used original screen if there same problerm again then ios 11 is on not stabel
that is because of embedded touch IC on the screen from iphone 6s. what we need to is just to wait for new update from apple like last time about home button with touch ID issue
"original lcd refurbs are not having that problem.
the china copy/ aftermarket are the ones that in question atm. 3rd supplier we contacted just told us that their original grade screens work, but there are running more test to make sure there arnt any other problems. Their china lcd ones dont work ATM and they are trying to figure out a solution. the other supplier said they are working on figuring out the lcd/touch compatibility issue with ios 11."
I replaced a friend's iPhone 7+ before iOS 11 was released. He broke it again (the aftermarket screen I fitted) and he gave me the phone with iOS 11.0.1 on it! Replacement broken screen touch works fine and I've just replaced it again for another new aftermarket screen; everything works fine!
I've taken photos of the rear of his original Apple screen as well as the two replacements screens. All the chips have digits printed on them.
Update (10/08/2017)
Ah, so this is the chip I have photos of, with the digits. The thinner silver chip is blank...
