A bit of odd behaviour from my (non-rooted) S3 that I'm finding a little worrying:
Last night I picked up my phone to set the alarms before going to bed and I found something unusual had happened - it seemed to have, without being prompted (on my part, at least!), mostly reset everything - the home screen was blank, with a few widgets present but unconfigured, and no icons beyond the most default ones present. However, if I went into my app archive, they do still appear to exist. Dragging (say) Sleep As Android out seemed fully-functional, and had my preset alarms present (but switched off?), but the archives seemed to have been emptied. Podcast Addict had lost its subscriptions. Most worryingly of all, I can't enter Settings; it gives an "Unfortunately, Settings has stopped" whenever I try.
SD card contents appear to be intact, the gallery's still populated with content, but I'm not sure if that's consistent - I thought the podcasts from PA were also on the SD, but they seem missing.
The most notable thing I did the day before which was unusual is that I turned on developer mode, but all I did in the mode is turn off the
various animation features which slow things down somewhat. It appeared to work absolutely fine; I listened to a podcast on my walk home last night, then left the phone on charge while I did other things; it was only just before I went to bed and looked again to find it like this.
I've booted into Safe Mode and it appears much the same; can't get into Settings, icons still missing.
I'm expecting to have to do a Factory Reset - I believe I did a recent backup, so shouldn't be too harmful - but I'm still wondering somewhat about what may have brought this about and what I could do about it. Would there be any logs buried anywhere?
Edit: Cut The Rope did prompt me to "Restore progress from other version of Cut The Rope". That suggests the data's still knocking around
somewhere.
