NewUser Any solution for this bug ?
It doesn't seem as if this is happening to lots of people, so it may well be a hardware problem rather than a software problem.
Unfortunately, maybe the best way to decide what kind of problem it is would be to wipe the device and flash it back to the Google's stock OS. If it's still there, that would be hardware.
Since that's drastic, it might make sense to first try blowing out the port with canned air.
