This seems like an incredibly bizarre issue and despite a decent amount of searching around, I can't quite find an on point discussion about my issue that could lead to a resolution which makes me think it isn't a common problem. Basically, I try to keep my phone on vibrate mode but I keep noticing that when I go to use it, it is often showing the sign for no sounds at the top and vibrate is off. I have a case that makes changing the volume involve a fair amount of force so it isn't a pocket problem and this issue is also happening when my phone sits untouched on my desk so it has nothing to do with bumping into volume buttons or anything like that.
A couple of other tidbits. When the phone has volume on, it stays that way and doesn't change over time and the same holds true for when no sounds are on. It is only one direction and that is from vibrate to no sounds. The timing of the problem seems really hard to gauge and I don't think it is fully consistent. Basically, I put the phone on vibrate, and any time between a few minutes to around 12 hours later, it will be back on no sound through no choice of my own. Most of the time when I go to bed with it on vibrate, it is on no sound by the time I wake up, but not always. I can't recall going days with vibrate staying on ever.
All I can think of is that something running in the background has some very strange setting that is doing this but I can't imagine what. I don't really have any unusual apps or anything of that nature and the vibrate does work on the phone seemingly fine when it is still on.
I would greatly appreciate any advice or possible fixes to try. I am hoping (ignorantly) that the 4.2.2 update will somehow resolve this problem, but I have no clue and that is mostly just wishful thinking. Please let me know what you think!
edit: the only other potentially relevant info I can think to add is that I bought a locked at & t phone but have unlocked it and swapped the sim to a european sim. I can't see why that would be relevant but figured I'd put it out there.
