Fix, microSD card is not detecting or SD Card not working on Galaxy A50

Remove and Reinsert MicroSD card

  • Turn off your Galaxy.
  • With your phone’s screen facing you, remove the card tray. You can use the insertion/removal tool (or a paperclip) to unlock the tray by inserting it into the provided slot. This small hole should be visible on the top part of your device.
  • Remove the SD card from the tray. You can lift the card up from the bottom. To assist, use the opening on the opposite side of the tray to dislodge (using a fingernail).
  • Remember to also re-insert the SD card while the phone is still off.

Check Whether SD card is working or not

The next good thing that you can do if your Galaxy is still not detecting the SD card is to ensure that the card itself is working. If you have another phone, insert the SD card in there and see it gets recognized. Then, try to save a file or files to it to check if it does receive file transfers normally.

Simple Reboot or Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always an ultimate solution for any issue.
