LG G3 SD Card Keeps Unmounting: Solutions

If your LG G3 SD card keeps unmounting, you’ll have to troubleshoot to figure out the problem. The easiest way to do this is to try one of the fixes outlined below to see if any of them rectify the situation. If the following methods don’t work, you might need to take your G3 in for a repair. 

LG G3 SD Card Keeps Unmounting: Solutions

1. Reinsert SD Card & Restart Your Phone

If your Android SD card keeps unmounting on your LG G3, the first thing you should try is reinserting the card. Simply eject it, then put it back in. Often, that’s all you need to do to fix the issue.

However, if reinserting the card doesn’t work, you can try restarting your phone. There are two methods for this. You can either reinsert the card while the phone is off, insert it when you turn it back on or leave the card in during the restart.

2. Unmount and Mount SD card

The next option for fixing your SD card is unmounting and remounting it manually. You might ask, “OK, but how do I unmount my SD card?” Luckily, it’s an easy process that only takes a few minutes. 

First, turn your LG G3 off. Then, insert the SD card into the SD slot and turn your G3 back on.

Once your G3 starts up, head into settings and tap “Storage.” Find the “SD card” option and click “Format.” This will reformat your SD card. 

Once your SD card’s formatting completes, you can tap “Mount SD card.” Then, you should be all set.  

3. Format the SD card with the Computer

Another option for fixing your LG G3 SD card woes is to format the SD card with the computer. It’s not as straightforward as reformatting directly on your device, but it might fix your problem. Note: your computer will need an internal or external memory card reader to complete this task. Also, don’t forget to create a backup if you have data on your SD card.

Start by inserting your SD card into the card reader. Then, launch Windows Explorer using Windows+E or the Start menu. Then, find your SD card in the list of storage drives and click “Format.”

When the Format menu pops up, ensure each option is configured to your liking. Then, click Start to begin reformatting. A warning message will appear, reminding you that reformatting your card requires erasing all its data. Double-check your backup is secure before continuing.

After your card formats, you can eject it and place it back in your G3.

4. Clear Caches Under Recovery Mode

If your Android SD card keeps unmounting after formatting attempts, your next option is to clear your cache. Although your SD card doesn’t have a cache, your device’s internal memory does. Fortunately, Android devices make it easy to remove cache data to start with a clean slate.

On your G3, go into your Settings. Find General, then select Storage. You’ll see that your storage is split into multiple categories:

  • System memory
  • Used space
  • Cached data
  • Miscellaneous files

Tap “Cached Data.” A window will pop up asking if you want to clear your cached data. Select “OK.” For best results, restart your device.

Removed SD Card Without Ejecting

If you’ve ever used removable storage on a computer, you know how important it is to eject a device properly. The same goes for SD cards in phones, tablets, and other devices. Unfortunately, it’s pretty easy to accidentally eject a card, which might cause you to worry about your data. You have a few options if you remove your SD card without ejecting it.

  • Finally, if neither of the above work, you can find and run a recovery program to retrieve your data. Upload your data to your computer, then remount your card as usual. 

Why Is My LG Not Reading My SD card?

One of the most frustrating things about using an SD card is when your device won’t read it. It’s a common problem, and there are a few reasons why your LG might not read or be able to read your SD card.

The first possibility is a dirty card. Sometimes, dust or other debris can get into your SD slot and make it hard for your card to mount properly. So, eject your SD card and dust it off. If you have a bit of contact cleaner, you can use a bit of that.

If you’ve cleaned your card and your phone still isn’t reading it, try restarting your phone. Sometimes, it’s just a matter of a phone glitch. In most cases, all it takes is a simple restart to get up and running again.

If your card isn’t dirty and your phone isn’t showing any glitches, you might have a corrupted SD card. You can find out if that’s the case by inserting a different SD card. If your phone can read the new card, the issue is your card.

How Do I Fix a Corrupted SD Card?

If you’re unsure how to know if your SD card is corrupted, your best option is to put it into a different card reader. If that reader can’t read it, the card is probably corrupted. However, there are a few things you can try to fix the issue.

1. Update your phone. Many companies run fixes for firmware, software, or apps regularly. If you haven’t updated recently, try doing so.

2. Check your SD card’s switch. Some cards have a small switch that needs to be turned on to grant write access. Make sure yours is flipped to the “On” position.

3. Look for damage. If your card is broken, scratched, or damaged, it could become corrupted. 

4. Clean your SD card and card slot to remove any debris.

5. Finally, if all else fails, you can format your SD card. Remember, this will erase all your data, so make a backup if you can.


SD card issues can cause LG G3 owners a lot of trouble if you’re unsure how to address them. Fortunately, if your G3 keeps unmounting, there are plenty of ways you can troubleshoot to solve your problems.
