Home button not working correctly after replacing battery

After I replaced my battery my home button is acting very strange. Touch ID is fine, but the click is very strange now and then. Sometimes it works perfectly fine and other times its freaking out. When I hold it for example it keeps clicking, when it’s supposed to click just once. Does anyone have an idea how to solve it?


I’ve already tried to loosen the screws, checked the cable for tears, none visable. Hard reset doesn’t work either..

Thanks in advance.

Hi Robin,

There might be a loose an intermittent connection from your touch ID to the display assembly, or a dodgy connection between the screen assembly and the logic board. Have you tried taking it apart again and disconnect and reconnect all the cable connections?

Sometimes where there is a misaligned connection the buttons/screens etc work intermittently.

Hey there,

I just took everything apart again, checked the the cable from the button to the screen and from the screen to the motherboard. That didn't solve the problem, there must be a tear internally in the cable from the screen to the motherboard is my guess. Or does anyone have another idea?

Hi Robin, The button is mounted with a bracket behind it. From a repair a few years ago i remember something with the pressure of this bracket. I'm not sure because i don't use iPhone's myself and only assisted with the repair back then but you could give it a go and change the tightness of the screws to see if you notice a difference in the mechanics of the button.

Hey Gmantunt, I've tried to loosen te screws but that didn't help either :(. I've ordered a new screen and a taptic engine just to be sure. Gonna replace them both tommorow, I'll let you guys know if it helps.

Hi Robin, sorry to hear replacing didn’t solve it for you. But don’t give up yet, there are more options. Sometimes it takes a while to find the thing that isn’t working right.

I read that a software reset might help. That’s an easy one to try.

If that doesn’t work check out iPhone 7 home button not working after screen replacement @rany.

Rany put together a extensive list of known facts and number 6 seems like a possibility for your problem.

FACT 6: in some instances, a chip (other than the one in FACT 1) present on the home button is damaged (specially during transfer of home button from broken to new screen). When damaged and failing, this chip will prevent home button function from working such as to exit an app and go back to home screen. But the finger print scanner would still be working and you are able to wake/unlock the screen with your finger/fingerprint and use reachability. This chip is accessible (contrary to the fingerprint scanner chip in FACT 1 which is practically unreachable) can be replaced and the issue can be fixed. Sometimes a partial tear to the home button cable can cause the same failure. It is also repairable by some people with the right tools, skill, and patient mindset.
