I have no idea what's happened to my tablet. It worked fine last night and then this morning when I turned it on it looks like it has reformatted itself and I get a warning "Low on Space - Phone storage space is getting low." When I click on it it takes me to the Manage Applications and it's showing all the factory apps with nothing that I've downloaded. From here I got to ES File Explorer and it's showing "SD Card unmounted or not preset". I've tried a factory reset, I've tried reformatting the SD card on both the tablet and my computer without any problems. But it's still showing there is no SC card. I'm at a loss what else can I do? Thanks in advance.
