hi! I got my Galaxy S3 Aug 2012. While in the USA was using my S3 and got the Jellybean update. I started to notice early Dec that it would unmount my SD card and since i have most files on my 32 BG class 10 card; i had zip on my mobile phone memory save for the important stuff. there are days it would read the card but since Jan 2013 i would always have the SD card icon on top telling me it is blank or has unsupported files. is this a problem with the Jellybean update? I have previously had the S3 checked but it was because my class 4 sd card could not handle the HD/HQ pics and videos i took hence the class 10 upgrade. can i rollback before the jellybean? my boyfriend upgraded to jellybean last week and has since had the unmounted sd card problem. i'm a newbie and i hope this is the proper place to post this query. thank you! help is much appreciated! 1.)

Philippines hi! i'm not sure if this issue was raised and i have not checked the other listings/threads but i noticed since the upgrade to 4.1.1 firmware the galaxy S3 goes through a stage where it unmounts my sd card and would not read anything on it. i would get constant notifications of the unmounting, trying to format and unreadable status of the SD card. i had initially thought it was because i was using a class 4 micro SD card but i have since then replaced it with a class 10 32 BG micro sd. is this because of the latest firnware? is there something i can do about it? i have a friend who also upgraded to the latest firmware and gets the same problem. thank you. would like to hear from you all.
