Home button is erratic
A friend bought a used iPhone 8 plus. The screen had a line running down it and the home button was “sticking" and would click randomly.
While replacing the screen I noticed that the taptic engine was the wrong size. It turns out it was from an iPhone 8! I ordered a new one from AliExpress and installed it thinking that was causing the issues. Unfortunately it's still happening.
Currently, the home button will work fine (albeit not very responsive) right after powering on but after a while it will stop responding and will also randomly activate with nothing touching it.
Touch ID doesn't work - I get the warning when turning it on. I have the feeling that it is an original from another phone - possibly even an iPhone 8 instead of an 8 plus.
Any insight into my paranoia?
Es esta una buena pregunta?
