Support Samsung Galaxy SII USB Storage problem

view story

http://androidforums.com – ... I think. I recently upgraded to ICS, a week ago, and things have been shiny. But earlier today my phone went crazy and a whole swathe of apps stopped working. These are all apps that are on the usb storage of the phone. It isn't a space issue as I have 2.79gb on the usb(out of 11.5) and 1.53 on my sd card(out of 7.4). I've tried restarting the phone. I even dropped the battery out to see if a hard reset would help but it didn't. My phone's still in warranty so I could return it but I really need its gps features for a project I'm doing at uni next week, talk about perfect bloody tim (General)
