home button replacement assistive touch won't go away
i had to replace the home button on my iphone 7. got a 3rd party button on ebay that looks exactly like the kind sold here on ifixit. the home button function works great, Touch ID does not (as expected). i recently upgraded IOS from 15.1 to 15.7 that's when the weirdness started. after the upgrade the Assistive Touch (on-screen) Home Button was turned on. i'd turn it off, but it would just turn itself on again.
searching the internet, i found some suggestions about settings in the Accessibility section, but none of those made any difference.
i read in a few places that (and this is conjecture from multiple sources) this is a new "feature" in IOS 15.6 (and later), that when IOS detects there "is a problem" with the home button (meaning it doesn't see the one that was shipped from the factory) it very helpfully turns on the Assistive Touch on-screen button - whether you want it or not. and even if you turn it off, it IOS doesn't care and will turn it back on.
does anyone have any additional light to shed on this?
i get that Apple is just trying to make the user experience better - we're from the government, we're hear to help you... - but when we switch the setting off, it should stay off. "No" means "No" Apple!!!
thanks for any insight you might have.
