Yes, it's been happening to me too when unlocking the phone (and seemingly more recently over the last week).

Using a Sandisk Ultra card and on the standard 4.1.1 ROM.

Let me guess, you are all using sandisk ultra cards? These cards appear to be a real pain in the a s s . Mine, (bought new off Amazon in October) went tits up and I believe it was the card that somehow caused corrupted files and caused my "media" process to be a complete battery hog.

About a week before the card totally failed to be recognized by my computer or my phone, I got those random messages about my sd card being unmounted and then it would just automatically scan it as if I had just inserted it when in reality I never took it out. I was able to copy everything to my computer about an hour before it was complete toast

I suggest you copy any important files on the card to your computer or wherever before it completely fails. I don't know what to do about getting a new card. I already filed a warranty claim with Sandisk but I am hesitant to use their brand again. Sandisk seems to be THE brand out there. I would like to try another brand.
