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.

My views on this issue

I have started facing this issue since the past 3-4 days and here are my views that can also serve as valuable information for everyone else:

- This error message started to appear only after I upgraded to android 4.1.2 by flashing the stock rom via odin.
- Im also using the SanDisk Ultra Class 10 32GB card
- I have not rooted my phone after upgrade and my phone is in fully stock condition, although it was rooted before.
- I dropped my phone once. But it was a very minor drop and everything was fine after the drop as it was on 4.1.1 at that time and i was on the same for further 10-15 days and never witnessed the error during these days..

These things should also be considered-
- The method of copying data from PC to phone. I use data cable and copy to the folders while the card is in the phone.
- Whether you remove the card without unmounting it.

I have tried formatting the card from windows using fat32 setting. It didnt help.
Formatted it with the phone and still saw the error once in the past 24hours..

In future, if I encounter the same problem, I might get the card replaced by visiting the sandisk service center here in India. Or, I can try flashing 4.1.1 again and revert back the result. As of now, everything seems to be fine as I have not seen the error for about a day or so.. (Fingers crossed)

    I have the same problem in 4.1.1. Stock, NOT rooted, ever.
    Brand new SanDisk Ultra 32GB class UhS-1, bought from the official Amazon store.
    Been seeing this problem about the same time since I got official 4.1.1 update from Kies. Formatted it in computer, and in phone, then the problem seems to go away for a few hours, but comes back within a day. What a battery hog, not to mention it can't be healthy for the card!

    Trying exFAT format now. Will report back.
