My phone displays a message "SD card blank or has an unsupported file system."
I can only get my computer to read the card again by removing the card from the phone and reinserting it. I shouldn't have to do that. The SD card should not get screwed up just by using a file managing app. Again, I like this phone and I want it to work! What to do?
Try to reformat your SD card. Back up the files you want from it, mount your phone to how it is working and you can view files on your computer that are on the SD card, right click on the SD card and select format. Be sure to set it to FAT32. Restore the files you backed up, and unmount and see how it works. Good Luck!
