Fix, MicroSD card is not detecting or SD Card not working on Galaxy S20, S20+ or S20 Ultra

Remove and Reinsert MicroSD card

Turn off your Galaxy.

Warning

Removing an SD card while the device is on may result in corrupted data.
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 the 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 the ultimate solution for any issue. Not only Pixel but this applies to each and every electronic device. I used to tell my mom to restart her device if she faces any issue with her smartphone.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

Press and hold the Volume Down button.
While holding it down, press and hold the Power key.
Keep the button held for 10 seconds, it will be restarted automatically.

If this doesn’t work then head to the next method.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

Open the Settings app.
Tap Device Care.
Tap the 3-dot at the top.
Select Auto restart.

Format SD card

From home, tap Apps.
Tap Settings.
Tap Device maintenance.
Tap Storage.
Tap More options.
Tap Storage settings.
Tap SD card.
Tap Format.
Confirm by tapping on Format.

Reset App Preferences

Open the Settings app.
Tap Apps.
Tap on More settings at the upper right (three-dot icon).
Select Reset app preferences.
Restart your Galaxy and check for the problem.

Clear Cache from Recovery Mode

In case you don’t know what is recovery, the first thing the bootloader rings up is the recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. And you can fix some problems with your phone.

This clears all the temporary data from the device. And then it works like new.

Your device must be connected to the internet.
Your device must have enough space to download the update.
Your device should have enough charge, more than 50% to install the update.

Troubleshoot apps in Safe Mode
