Hello guys, I run a repair shop, where I several times hav replaces cracks iPhone 7 screen some of them work with the original home button and other not, they finger print still working but not the button some times, I am sitting right next are rose color iPhone which have this issue, I have run a DFU on it with iOS 10.3.3, and now the button is working but it taps more than 5-6 time at once push, what is the problem, I have tried 3-4 screen, stil same problem?

Loosen the home button bracket screws; they are probably too tight. Loosen them very slowly until it works correctly.

the cable was damaged on removal, they need heat to loosen the glue, the u10 chip is soon delicate be careful
