Has anyone else seen the iPhone 7 home button stop working after only disconnecting the battery? At our shop we have been replacing screens on the iPhone 7 since December of last year. We have not had any problems with the home button becoming deactivated after a repair till about a month ago. We started seeing a few cases where the phone button would not function after putting on the new screen. The phone would either not wake up from a black screen and only recognized it was being pressed when the screen was on. Then after entering the passcode it would not function at all. Sometimes it gives a messaging saying “iPhone home button needs servicing” and automatically activates the assistive touch. In other cases it just says the familiar “unable to active touch ID” like it has with all the older models with touch ID functionality. This may be related to which IOS it is on. Until a few days ago we assumed it was the screens we were replacing it with since we did not damage the home button in any of the cases. But this week we tested an iphone 7 that someone brought us with a cracked screen. There was no issue with the home button after the screen was cracked and no message saying “iphone home button may need servicing” All we did was power off the phone and disconnect the battery with the screen flex cables still attached. Then we reconnected it and upon bootup the phone gave the “unable to activate touch ID) message. This might be a software but with the version of IOS the phone was on, sadly we were unable to check.
I think it is pretty common for Touch ID to require a power cycle to work. We know that the 7 home button is very sensitive to overtightening the screws at the button plate, and we know that some copy screens have home button flex issues. My guess is that your prior problems were likely the screen like you’ve concluded, and that this one just needs a power cycle.
Home button was not working when fixed the screen. I went back and lossen the screws and it was working, I turned it off and waited a couple of days to give it to the owner, then when I turned on to test it, it was not working. Help..
My guess is you have unknowingly damaged the flex cable where the plate screws on, they are super easy to tear or just slightly nick. Have you tried a new screen?
I think this issue is most commonly a small tear or Nik in the cables between the phone base and the screen that get torn during movement.
Was this ever solved? I have a problem similar to this. Battery cable disconnected and home not working anymore
I believe its the flex cable on new screens, ive tried 3 different screens and home button still doesn’t work, replaced old screen and worked fine, the phone also takes a while to boot with the new screens, assuming this is because its trying to connect with the home button but failing? bought another screen from different company and this worked fine. trying so many different screens can wear out the connector so be careful
The bracket on the back of the lcd is pinching the cable… Solution… bottom left screw ( only non y screw) screw it in without the bracket and let the bracket lay on top of the screw
Hi, I changed upper speaker, and after assembly phone back, my home button is not working. I didnt touch home button, dot touch any screws, but before opening i heated phone by hairfan… maybe it is big mistake send heat to phone. I want to glue make easyier to open… any ideas?
Jeff Lauer suggested: “There is a work around not the best, but it will work. ….. Snipped ….. If your home button is inoperative, you can reboot the phone use your passcode to get access; you can now go to one application only so pick settings. First got to display and brightness set Auto lock to never Next in settings select Accessibility then select touch. Now turn on assistive touch and set up 2nd tap for app switcher there is now a new home button on the screen. To close any application double tap the new home button swipe and close applications ….. Remainer Snipped ….. I did this, but: 1- I didn’t disable Autolock 2- I did ‘Turn on the Assistive Touch”. It is sufficient to get going. It does add more steps for most operations, but I’d rather do this than caugh up hard-earned cash to Apple. Maurice
