I was having mic issues where it would not work and got it fixed by replacing the motherboard at UbreakIFix. After the replacement and installing my backup, now apps just don't work. Phone app constantly crashes and freezes. I can't take videos on my phone or other 3rd party apps even in safe mode.

As someone who's been happy with their Pixel since day 1, it really sucks that the phone has just started to [censored]out on me since Android P.
