first time posting a query here.
my Nexus 7 has been plagued by this problem for about a few months. assuming it was a bug, waited till the 4.4.3 update arrives.
have updated it, but the problem still persist.
the video is at youtu.**be/**bZLHorAuScw (just delete the *)
any ideas on the cause of the prob?
anyway, the device is still a virgin (have yet to be rooted) and has never been dropped. only use it to play games, watch movies and read ebooks and pdf files...
thanks for all your feedback.
