Blank USB Storage.
Okay forum, i need your help. I have a galaxy ace 2, and when i was on the internet, suddenly my phone crashed and rebooted and surprisingly, i found this little question mark sd icon on my notifications, so i went to check it. It says "Blank Usb Storage - USB storage blank or has unsupported file system. I tried rebooting, formatting, and even trying a factory data reset but to no avail. When i try to click format it just says formatting for at least about 1 second then it just finishes, but the icon is still there.
