Top 4 Samsung Galaxy Note 2 microSD Card Problems You Might Face

Storage device used on Samsung Galaxy Note 2, otherwise known as microSD card, is among the components that often catch problems. In fact, there are more owners complaining not being able to find contents saved in their microSD cards than not being able to connect to the internet. Based on emails we receive from our readers, there are four microSD card problems you may encounter when you’re a Galaxy Note 2 owner.

Problem 1: Content Not Found

Many owners reported they can’t find files they saved into their microSD cards using the Galaxy Note 2 while others complained the phone just refuses to detect the storage device.

Possible Causes 

  • Temporary phone problem.
  • Using an unsupported microSD card.
  • The content is not supported, used by another app, corrupted, DRM-restricted or was inadvertently deleted.
  • The microSD card or its slot has been damaged.


#1. Reboot the phone to see if the problem is resolved after that. Temporary device issues can be fixed by simple reboot and it should be the first thing you need to do.

#2. Check if the microSD card you’re using is compatible with your phone. If it is, then it could be just a mounting issue, otherwise, you need to buy a new one.

#3. Make sure the file you’re trying to access is supported by the phone or not used by a different app. Digital Rights Management (DRM) restricted files may not be accessed like other files. Also, you need to check if the file is still in your microSD card.

#4. Check if your microSD card is still working properly. You can let your laptop read it or other devices to check if it’s okay.

Problem 2: Cannot Unmount microSD Card

If you cannot unmount your microSD card, it could be that it  is being used by an active application, open or running in the background, and the card cannot be unmounted until the application is closed or finishes its current action. You can do the following to fix it:

  1. Open the Task Manager by pressing and holding the Home key for 1–2 seconds, and touching Task Manager.
  2. Select the Active applications tab.
  3. Touch End all, review the message, and touch OK.
  4. Attempt to unmount the card again. From the Home screen, touch Menu Key > Settings > More Tab > Storage > Unmount SD card.

Problem 3: Cannot Detect microSD Card

If your phone has a difficulty of detecting the microSD card, it couldn’t be mounted properly. The possible causes are:

  • Defective microSD card.
  • The card was not properly formatted.
  • The card is corrupted.

If the microSD card is defective, there is no other option but to buy a new one. However, before you do that, try to reformat the card to see if you can remedy it. Doing this would also fix corrupted microSD cards.

Problem 4: Unable To Format microSD Card

One effective way to fix microSD card issues is to reformat it. But what would you do if you can’t?

#1. Reboot device to eliminate the possibility that it is just a temporary device issue.

#2. If the card was used in a previous device, it is possible that the card may be write protected. A write-protected card cannot be formatted. To remove the write protection, you will need to install the card in the original device and remove the write protection. If the original device is not available, you will need to use a different card in this device.

#3. Inspect the microSD card slot and microSD card to ensure the connectors are not corroded, bent, broken, scratched or pushed in.
