Switched my SD card from Samsung 7S to Samsung A51. Now it's not being recognized by my A51.

Hi @AnnieO55,


Thanks for reaching out. Allow us to assist.


There are some troubleshooting options we'd like for you to try. The first is reinstalling your SD card. Unmount the SD card by going to Settings > Device maintenance > Storage > More option > Storage settings > SD card > then select the option to Unmount.


Turn off your device and remove the card. Make sure there are no visible signs of damage etc. Insert the card back in and turn your device back on, and see if this helps.
