galaxy note 2 microsd card

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.

//This is the continuation and last part of the prior post on four common microSD card errors with Samsung Galaxy Note 2.

C. microSD Card Unmounting Problems

There also some instance when you cannot unmount the microSD card, possibly because the microSD card is being used by any active application in the background. In this case, you have to let the application finishes its current action and have it closed to proceed with unmounting the card.


  1. Open the Task Manager. To do so, just press and hold the Home key for 1 to 2 seconds and touch the pie icon to continue.
  2. From the available tabs, select the Active applications tab.
  3. Touch End all.
  4. Read and review the prompt and touch OK to continue.

    1. Touch the Menu icon from the home screen.
    2. Touch to select Settings.
    3. Touch to select More options for storage.
    4. Touch Unmount SD card.

D. microSD Card Unable to Format

When you cannot format the microSD card, it is possible that you are using unsupported microSD card or it is write protected. In this case, we recommend you to follow the standard process to determine the cause and then get the problem solved.

  1. Remove the battery for 30 seconds with the device still on. Wait for a moment and replace the battery.
  2. Turn on the device.
  3. If you were able to use the card in other device, it is possible that the card may be write-protected. If it is write-protected, it cannot be formatted.
  4. Remove the write protection to enable the card. To do so, you have to install the card in the original device and remove the write protection. If you do not have the original device, then you have to use a different card in this device instead.


  1. Check for any signs of liquid damage on the device. See the LDI inside the battery well and on the battery itself and see if they are in solid white or white with visible pink/purple Xs. Otherwise, the device is experiencing liquid damage, especially if it has been exposed to moisture. In this case, the device needs repair or physical restoration before you can proceed with the formatting process.
  2. Also check the microSD card slot and microSD card for any possible signs of physical damages like the connectors are bent, broken, corroded, pushed in or scratched. If so, then have an authorized technician check and restore it.

If all else fail to resolve the problem and you still cannot format the microSD card, then you should consider replacing it with a new or functional microSD card instead.
