How to Fix Insufficient Storage Available Error in Android

If you're seeing an "Insufficient storage available" message on your Android, chances are that you've used up most of your device's available memory. To rectify this, you'll need to make some space by deleting apps and/or media; you can also add external storage, such as a Micro SD card, to your phone. In some cases, however, this error shows up even when you have plenty of space. If this is the case, you can restart your phone, reset your apps' caches, or reset the Google Play Store to resolve this issue.

Method 1:
Check your phone's available storage. On older Android models, the "Insufficient storage available" error was often a result of a system malfunction--not necessarily an actual report of insufficient storage. Before continuing, verify the status of your phone's storage.

• You can check your Android's storage from within the "Storage" section of the Settings app.
• If your phone has more than 15 megabytes of storage, you may be encountering an error not related to your storage.

Restart your phone. To do this, hold down your phone's power button, then tap Power Off or the equivalent. Once your phone has powered down completely, press and hold the power button again until your phone's screen lights up.

• Restarting your phone will reset your system's RAM. Doing so will both speed up your phone and potentially solve the "insufficient storage available" error if the error is unrelated to your phone's memory.

Delete any unused apps. If your phone's memory is actually low, you can quickly free up some space by removing any apps you don't need.

• To delete an app, tap and hold it, then drag it into the "Remove" field (usually the top of your screen) and drop it there.

Delete unnecessary media. This can include pictures, videos, and so on. Since these files can take up a fair amount of space, clearing out just a few can improve your phone's memory substantially.

• If you don't want to delete certain photos or videos, you can back them up to Google Drive instead.

Clear apps cache

To fix "insufficient storage available" on your Android phone, you can easily clear some unused apps or app cache on your device, because the applications which are being run in your device currently take the valuable space by their cache data. In this method, we would clear the app cache for each app one at a time.

Step 1.Open your Android device and go to "System settings".

Step 2.Tap on the "Apps" option to select it.

Step 3.From the new window so obtained, scroll down the download section of the "Apps" tab.

Step 4.Tap on any particular app to delete its cache.

Step 5. With the screen of the respective app that you have selected, tap on the "Clear Cache" option to free up space.

WARNING: Don't tap on the "Clear Data" option as it would delete the important files of the application from your device along with the cache.

Step 6. Repeat the steps for each app, which will keep on increasing the free space and the error would not appear any longer.
