So I posted a week or so ago about my phone falling out of my pocket and afterwards a vibration/static noise while talking on the phone. Turns out one of the corner screws had worked itself loose and fell out. It was only still there because the cover was on. So I reinstalled it with a t6 bit and decided to check the others. they were only held in by a thread or two each. couldn't check the one because of the void sticker.
Now no more vibration, also could have potentially destroyed the phone had it dropped again.
