Use Free Up Space on Android
On Android 8 and later, there’s a built-in tool that will remove downloaded files, photos and videos you have backed up online, and apps you haven’t used in a while.
Back Up Photos in the Cloud
The Google Photos app backs up your photos and videos to your Google account so that you can delete them from your device. You can then view and download your pictures on the web using your PC or any other device. Google Photos should do this automatically, but to be sure:
Delete Android Apps
Like your photos and videos, your apps and app data are automatically synced with your Google account. That means when you delete apps from your Android, you can re-download them later along with all your associated data. In other words, if you delete a game, you won’t lose your progress, so long as it’s backed up to the cloud. When you’re running low on space, go ahead and uninstall any apps you rarely use. If you don’t want to remove an app, another way to free up a minimal amount of space is to delete your Android cache files. In newer versions of Android, there’s no way to delete all cache files all at once, but you can clear the cache for each app individually.
Offload Apps and Photos
Likewise, you can move Android photos, files, and apps onto a memory card or your computer via USB cable. If you have pictures and videos that you don’t want to be uploaded to your Google account, it’s a good idea to keep backup copies elsewhere. You can even set your default camera storage to the SD card by going to Camera Settings > Storage Location > SD Card.
Use a File Manager to Free Up Space
Third-party file managers save internal storage space on your Android by deleting duplicate and unnecessary files. They can also help organize your files by creating folders, making them easier to locate. In addition to built-in Android cleaners, many file manager apps come with other tools for optimizing your device’s performance, so browse the Google Play Store to find one you like.
