How To Fix Samsung Galaxy A6 Not Recognizing MicroSD Card

Problem: My phone, a Samsung Galaxy A6, suddenly doesn’t recognize my sd card. There’s no error; it’s like I don’t have a card in the phone. I’ve had something like this happen before. I’ve taken the card out and put it back in. It’s not working this time. I’ve put the card in a card reader, and it still isn’t working. Is the card borked?

Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version first. If an update is available then I suggest that you download and install it first.


The first thing you have to do in this case is to isolate the microSD card to check if it is what’s causing the problem. You can do this by inserting a different card in to the phone. If the phone can detect this card then it’s very likely that the original card is damaged and needs to be replaced,

You should also verify if your card can be read by another device. In case it can be read then the problem is most likely caused by the phone in which case you should proceed with the troubleshooting steps listed below.

Clean the microSD card slot

There’s a possibility that the problem could be caused by dirt or debris stuck in the card slot. If this is the case then try cleaning the card slot using a can of compressed air then check if the issue still occurs.

Perform a soft reset

When you do a soft reset the phone software will be refreshed and will usually fix this kind of problem if is is caused by a software glitch. To do a soft reset press both the volume down and power keys at the same time and hold them down together for 10 seconds. You may feel your phone vibrating at some point but only release both keys if the screen turns on.

After the soft reset check if the phone can recognize the microSD card.

Check if the problem occurs in Safe Mode

There are instances when an app you downloaded can cause this problem. To check if this is what’s causing the problem you will need to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the phone off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

If the micro SD card can be detected in this mode then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

Cached data of apps is usually stored by the phone in a dedicated partition of its internal storage. This data helps apps open faster making for a better mobile experience. There are however instances when this cached data can become corrupted and can cause issues with the device. To check if this is what’s causing the problem you should wipe the cache partition of the phone.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key.
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe cache partition’.
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

Check if the issue still occurs.

Perform a factory reset

The last troubleshooting step you will have to do if the above steps fails to fix the problem is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before doing this step.

  • Make sure that the phone is off.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.
  • Once the phone has fully started do not install any apps in your phone yet. Try to check first if the battery drains quickly.

In case the issue still persists after the reset then this is most likely caused by a faulty hardware component already. The best thing you can do right now is to bring the phone to a service center and have it checked.
