The same problem, I have for deveral days, with no permanent fix... I have a Lumia 820 unlocked Greece.
I talked with #nokiacare and after several messages they told me to make a hard reset,
and I said no, because I search this fotum and onother person had already tried it with no results...
and then they told me to go to nokia care center for testing it. Which I haven't done it so far.
the issue is not within any app or game, I tested them, and still stuck the volume.
And I believe it's something about the os, because it happent after gdr3/black...
any other help or solution?
