S9+ Unsupported SD Card Error

Problem: Hi,  I have a Samsung Galaxy S9+.  It recently started saying Unsupported SD card.  I took it out and put it in the adapter and tried to read it on my computer and it also won’t read it.  I don’t really know what is stored on the card so I don’t want to format it. The phone is giving me the option of formatting it.  Is there a way to see what might be stored on the card if my computer won’t recognize it?

Solution: If your computer can’t read the card then chances are it is already corrupted. You can try using a recovery program such as Recuva to recover the data stored in the card however this does not work all the time. The best thing that you can do right now is to replace the card with a new one.

S9+ microSD Card Not Inserted Error

Problem: I have had no issues with my SD card until a couple of weeks ago, now when i open My Files under SD Card it will show how many Gbs used and available then flashes Not Inserted then back to GBs and Not Inserted again. When i try to delete anything on the SD card it fails to delete, also if i try to play any files they fail when they display they are available. Have tried everything suggested on here and still no joy. Haven’t dropped phone so not sure if its software or hardware issue, please can you help.

Solution: Try removing the microSD card from the phone then clean the SIM/ microSD card slot with a can of compressed air. Once this is done insert the microSD card back then check if the issue still occurs. If it does then you should try using a different microSD card to eliminate the possibility of this issue being caused by faulty card. In case the issue still persists then backup your phone data then do a factory reset. This way you can check if the issue is caused by a software glitch.

If the above steps fails to fix the problem then this might already be caused by a faulty hardware component. You will need to bring the phone to a service center and have it checked if this is the case.

S9+ Can’t Move App From Internal Storage To microSD Card

Problem: My phone is showing that the factory installed 64 GB of hard drive space is almost completely full.  I have gone into storage/apps and moved as many as possible over to the additionally installed 64 GB SD Card.  However, when I move an app over from the internal drive to the SD card, it does not show as freed up space.  Example: One of the largest sets of files is from the app “Line”, which is commonly used in Asia, where I live.  It shows as using almost 3 GB of space. When I move it over to the SD card, and then re check the space available on the internal drive…. the space available on the internal drive does not change.  Further, a few days later (definitely not immediately) Line will show up as still on the internal drive and I will move it over again. Still, no space has been freed up on the internal drive, but Line will show as moved to the SD card….. for a few days.    I have gone through every app of any size (over 50 mb) on the phone and moved every app that can be moved, to the SD card. Still I keep getting the message that I am running out of memory. The apps using the most space on the internal drive are Line, Facebook, Messenger and Google Play Services.   None of these (with the above strange exception of Line) can be moved from the internal drive to the SD card. And I am very leery of clearing data from Line, Facebook and Messenger because I am afraid that I will lose important conversations. This is very perplexing and frustrating. Any help would be greatly appreciated.

Solution: There are only a few selected apps that you can totally move from the internal storage of the phone to the microSD card. Usually, apps that store your sensitive personal data can’t be moved to the microSd card due to security concerns. There are also some apps that require the faster access speed of the internal storage which is the reason the app developer has not allowed the app to be moved to the microSd card ( which usually works at a slower access speed).

The best thing that you can do right now to free up some space on your phone is to move your data files ( photos, music, videos) to the microSD card. If you have stored a lot of video files on the phone then moving these files to the microSD card will free up a lot of space on the internal storage.

You should also consider uninstalling certain apps that you don’t regularly use to free up some internal storage space.
