Today while I was at work, I found that my Lumia 822 had systematically deleted track 1 from all of my albums on the SD card (a Sandisk 32GB). Over the course of troubleshooting, formatting, trying different cards, etc, it got to the point that not only did the phone no longer see any of my music, it no longer saw any of the photos on the card. When I plugged any of my cards directly into my PC, the data came up fine. When I connected my phone to the PC (which is apparently a good way to invite data corruption), I could copy my files back to it (except for Saved Pictures, which insisted that "the device is disconnected or no longer responding"), but they're still not visible as mp3s or jpgs - the storage app simply lumps them all together as "Other".
Furthermore, the volume keeps resetting itself to 13 when the screen goes into lock, no matter where I'd left it before.
I've not installed any apps lately (I'm not a big apps guy, primarily using my phone for work). I've uninstalled a few that I wasn't using. I'm running the dev preview of GDR3.
A hard reset is the last thing I want to do, but at this point, I'm out of other ideas. Anyone else seen their phone go Librarian-poo like this?
