Help! My S3 doesn't detect my SD card

[rjtim]

When I go to Settings > Storage, under the SD card option it just says 'Mount SD Card, Insert SD Card.' The card is fully clicked/inserted the right way.

My SD card is only Class 2, I think. Is this compatible with the S3? This card is from my old phone that I want to reuse with my S3.

It should be compatible with the older MicroSD cards. Have you tried a different card? That's the only way to know for sure if it's the card or not.

I've got the same problem here and it started after an update a week ago. After I updated the software, I couldn't see my pictures from sd card any more. I thought the update deleted them, but just yesterday I noticed that the phone doesn't recognize my SD card any more.
