this has happened before, but other times it has happened a simple reboot of the phone and it's fixed. I've tried rebooting at least 3 times now, and I get the same result. everytime I try to open up my picture Gallery, it flashes for a second as if it's about to open, and then closed automatically. no message of a force close or anything like that. just goes back to the home screen each time. anyone with any advice on how to fix this issue?
