回答先: After update to iOS 11 Touchscreen unresponsiveI just changed my iphone 7 screen today ios11.0.2 and my home button and touch id is working fine .Then I get an other update for ios 11.0.3 about an hour later and now I am afraid to update it just incase it bricks it. I will leave it on 11.0.2 for now till I get more info on this new 11.0.3. Saying that it does say it is is a fix for home button probs but I dont have any, so do you or dont you Desisions decisions. Edit: Updated to 11.0.3 2 days ago and everything is still working fine,.Conclusion: It could perhaps be cheap screens that are causing the problem or just your luck when buying a screen. I fitted a AAA screen about £10 -£15 more but in my opinion worth it.
