Whenever I go into a game, watch a video on YouTube or listen to music, there's this extremely annoying clicking sound going on in the background. I got the tablet 3 yrs ago but had it refurbished a few months ago due to another problem. It was working perfectly until a few days ago when a very frustrating clicking sound came on whenever any media was playing or if I was in a game. It went away after a few hours but it came back just now. I'll be very grateful if anyone can help me with this.

Welcome to Android Central! Is Bluetooth on? If so, try turning it off.

I did that but nothing happened

Does it still happen in Safe Mode? https://support.t-mobile.com/docs/DOC-28736

Yes

Since it happens in Safe Mode, it's a problem with either the firmware or hardware. First, try wiping the cache partition (which probably won't do anything, but it won't hurt to try): https://support.t-mobile.com/docs/DOC-28773. If that doesn't help, then the next step would be a factory reset. If that still doesn't help, then you could try reinstalling the firmware using Smart Switch (http://www.sammobile.com/forum/showthread.php?t=29914) or Odin (http://forums.androidcentral.com/amb...interface.html).

If none of that works, then it's probably a hardware issue.
