I have this one from Amazon:

It holds the phone great but just recently I started having an issue where the screen will turn off it its on when I mount it. It will also not turn the screen on using the fingerprint sensor even though it vibrates indication the fingerprint was accepted. Today I tried using the the sensor to unlock the phone; I picked the phone off the mount and the screen turned on but the status bar looked funky:
Makes me wonder if the phone is being affected by the magnet. Anybody else have issues?
