Everytime I start my phone up it says the SD card is or has unsupported filesystem. When you click on it.. it asks to format... you click "format" and then the phone just freezes. If I receive a picture in a txt and I click on it, the phone freezes. When I plug my phone into the computer through the USB cable, mount, and try to format it through the computer it says windows is unable to complete the format. I've reset the phone to factory reset also, no luck. Please help. It all started after I did the update, I can't even access the SD card through the computer to manually update it.
