I faced a problem with my
32 GB SD Card on
Samsung Galaxy Grand Prime. Device says
Damaged SD card. I changed it to a brand new (also 32 GB) SD card... And problem didn't gone. Each card read perfect via card reader, but not on my phone.. What can I do?
The grand prime is known to cause electrical damage to sd cards and without warning. I have two of these phones and they each destroy an sd card every 3 months. The cards may have self sensed damage and dropped into read only mode, in which case you can read them with a usb reader on a desktop but the phone will refuse to mount at all, and the will not be writable in any case.
