And when you suffer from this issue, you may need to think over these points:

  • Did you remove the SD card without turning off your cell phone last time?
  • Did you use this phone SD card on a strange or unsafe computer?
  • Did you use this phone SD card on other operating system (say from BlackBerry and back to Samsung)?

Instead of finding the location to unmount SD card and then carry out formatting in Android phone, the easiest way to do formatting is by using a computer.

The only thing you need is still an SD card reader. You can format SD card to FAT32 file system under Windows Explorer , Windows Disk Management and Partition Wizard Free .

The most significant difference among using these three utilities is that the former two prevent users to format SD card larger than 32 GB to FAT32 while the third one is able to.

After the formatting, insert the SD card and power on the phone. The device should then pick it up.

①: Use Windows Explorer

Step 1: Connect blank SD card with PC via card reader and make sure it is detected by the machine.

Step 2: Open My Computer/This PC, under Devices and Drives you can find the SD card.

Step 3: Format it into FAT32.

Solution 6: Replace SD card with another one

Sometimes when you format the card it shows "SD card unsupported try new one". In this case replace the SD card deserves a trying.

You may try this procedure with one of your small storage cards and see if the phone can detect or read it.

See the following example:

"I have a new 32 GB SD card. My Hisense tablet recognizes it when I put it there, but when I put it in my Alcatel One Touch Mega it says blank card. When I format it says erasing card and then does nothing but say blank or unsupported files. My 4GB SD card works fine in the phone, mounts and stores, but the new 32 GB will not work in the phone, but computer and tablet read it fine. I have formatted it multiple times and even downloaded SD formatter and used that as well. Nothing. Has anyone figured out this problem? Any help is appreciated." --from Tomsguide

If NOT, try the other cards and if it keeps bearing the same result, then it's the phone that has an issue, probably the firmware.


Since the phone can detect that there's a card mounted on it but couldn't read it, it's not a hardware issue but firmware. Check if there's an available update, if YES , go for it.

Solution 7: Contact the manufacture

If formatting or changing SD card is not helping at all, call the manufacture of your phone to get help.

Maybe Android phones need to fix this issue by making an update for their OS to support all kinds of micro SD types, or maybe all they want is to force users to buy their own branded micro SD card. It's hard to tell.
