Nokia Lumia 822 - My memory card is not working properly in Lumia phone

1. Switch off the phone and then remove the memory card. For information on how to remove the memory card, see your Nokia phone's user guide.

2. Connect the memory card to a PC with a USB or SD card adapter; your memory card should appear as a separate drive on the computer:

  1. If the memory card problem message box appears, follow the on-screen instruction to fix the problem.
  2. If the memory card is not recognised by the PC, it may be broken or password protected by the previous device where it was used. Neither Windows nor Windows Phone support password protection. Remove the password from the memory card with the previously used device.

3. Format the memory card on a PC. Before formatting the memory card, make sure you have a backup of the data as it is lost during formatting:

  1. Use Windows Explorer to navigate to the removable storage on the computer, right-click the memory card and select Format.
  2. For 4-32GB cards, select the file system FAT32 and allocation unit size 32 kilobytes and press Start. For 64GB cards, select the file system exFAT and allocation unit size 128kB.
  3. Confirm the data loss warning message. When the formatting process is complete, press OK.
  4. Restore only the data that is compatible with your phone (JPEG or MP4 in the photos folder or MP3 in the music folder).
  5. Right-click the memory card, select Eject, and wait until it is safe to remove the card.
  6. Insert the memory card into the slot in the phone until it locks into place.

The previous actions usually solve your problem. If they do not help, test with another compatible memory card to see if the issue is with the card. Some memory cards are currently incompatible with your phone. For optimal performance, we recommend a fast 4-32GB card by a well-known manufacturer, for example, SanDisk Extreme Pro, Toshiba Exceria, or Samsung Pro.
