Troubleshooting Galaxy S10 that can’t detect microSD card

First off, I would assume that you’re having problems with a new microSD card because if it’s old, there’s a chance that it’s already damaged or corrupt. With that said, here’s what you need to do to try and fix this problem on your Galaxy S10:

First solution: Make sure the microSD card is mounted properly

Mounting the microSD card is a no-brainer but sometimes things can go wrong. Thus, the first thing you should do is make sure your microSD card is mounted properly. Follow these steps:

  1. Turn off your phone first.
  2. Insert the SIM ejector tool into the card tray pinhole.
  3. Gently pull the card tray out of the slot.
  4. Now, re-seat the microSD card properly (with gold contacts at the bottom) and make sure it snaps perfectly on the tray.
  5. Gently insert the card tray back into the slot and make sure it snaps right back in.
  6. Turn your phone on.

Once the phone has successfully booted up, try to see if it can now detect the microSD card because if it still can’t, then move on to the next procedure.

Second solution: Format microSD card with your phone, if possible

You may have to do this procedure if mounted a used microSD card on your phone which you used with other devices. So, head to Settings and go to Device care. From there, touch Storage and then you could immediately see if the microSD card needs to be formatted. However, if you can’t see any mounted external storage device, then you may have to format the card using your computer.

You may have to use an adapter so that your computer can read the card. Also, take a little time backing up whatever files you don’t want to lose before formatting the microSD card. By doing this, you would also know if the problem is with the card or your phone because if your computer can also not read the card, it means it’s damaged already.

However, if your device cannot detect or recognize any external device mounted on it, then it means it has an issue. Before you device to visit a technician or bring your phone back to the store, it’s best to reset it first.
