How To Fix Samsung Galaxy S9+ microSD Card Is Unsupported Error
Problem: Last year my micro SD card went from storing all of my pictures to “unsupported”. It happened over night. I cannot read my SD card with any other device (not even recognize that there is a card in the card reader), though I’ve tried multiple. Whenever I try to open my SD card on my phone it prompts me to format it. I need the data so this is not an option for me. I took it into Best Buy and they said it would cost $500-$1000 to retrieve my data and that my SD may not survive. The guy working there said that since only my phone can actually recognize that the card exists, I need my phone to run a scanning program or something like that. Is this true? What else can I do to retrieve my data? I’ve also tried another card in my phone and it read it fine, so I do not think that it is an issue with my phone. Any help would be appreciated!!!
Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.
The first thing you will need to do in this case is to remove the microSD card from the phone then let your computer read it. You will need a card reader to do this. In case the computer can’t read the card then it is most likely corrupted already. It is going to be difficult to retrieve the data stored in the card once it gets corrupted. If you need the data stored in the card then you will need the services of a data retrieval company.
If your computer can read the card successfully then I suggest that you backup its contents by copying the data stored in the card to a folder in your computer. Once this is done format the card using the FAT32 partition then insert it back to the phone. In case the error message still occurs then perform the additional steps listed below.
Do a Soft Reset
The first thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.
- Press and hold the Power and Volume down key for up to 45 seconds.
- Wait as the device restarts.
Check if the issue still occur.
Check if the issue occurs in Safe Mode
Another factor that can cause this problem is an app you downloaded to the device. To check if this is the case you will need to start the phone in Safe Mode since 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.
In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.
Wipe the cache partition of the phone
The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occurring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold 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 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 problem still occurs.
Perform a factory reset
One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Take note that this will erase your phone data so make sure to create a backup copy before proceeding.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green 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 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.
Do not install any apps after the reset has completed. Try to check first if the phone can read the microSD card. In case it doesn’t then I would suggest that you just get a new microSD card.
