How can a home button/touch ID be the cause of an iPhone shutting off
This is a follow up question from my previous question about a water damaged phone. You can find that by searching in my questions.
To summarize, the iPhone I'm trying to repair would shut off or wouldn't turn on unless the home button/touch ID was disconnected. I thought it was the phone until I swapped the LCD and everything works. Mind you, it was under water but with the LCD swap, everything works.
This sparked my curiosity but also, I want to try and salvage the touch ID. What could be the reason? Can I just swap the flex cable? Testing will proceed, I just want to see if anyone had any experience with this.
