Not all Android smartphones have a spacious storage capacity, especially cheap models like Samsung Galaxy M10. Not installing too many applications might is a good step to keep your storage capacity from running out. In addition, you should also take another step like setting your messaging app to not automatically download the media and so on.
Regularly checking the remaining storage capacity is another good step to take. This way, you can control yourself from saving unnecessary files like memes you find on your social media feed. If necessary, you can also clean up your storage by removing the junk files.
In case you didn’t know how to check the remaining storage capacity on Android, following are three ways to do so.
Via the Settings menu
The first way to check the remaining storage capacity on an Android device is via the Settings menu. Not only you can check the remaining storage capacity, but also get rid of the junk files existing on your storage.
To check the remaining storage capacity via the Settings menu of Android, tap the Settings menu and select the Device maintenance option.

On the Device maintenance screen, tap the Storage option on the bottom. You can see the summary about the internal storage of your device on the top section of the screen.

From this screen, you can also figure out the size of individual apps and files. Simply tap one of the available data types to do so. You can also directly delete the files or apps that take too much space yet not crucial enough.
To check the remaining capacity of the external storage (if you have one), you can tap the SD card option on the bottom of the screen. You will also be presented a summary that tells you the total storage capacity, used space, and the available space.
Via file manager
Nearly all Android smartphones feature a file default manager. In Samsung, the default file manager called My Files. The major use of My Files (and other file managers) is nothing but to help you manage your Android files. But, you can also use it to check the storage capacity of both the internal storage and external storage (SD card).
Typically, you will see a piece of brief information about storage on your device on the file manager like the following.

Using Files
Files is a file manager app for Android developed by Google. In addition to managing files, you can also use Files to remove junk files on your Android device. Just like other file manager apps, Files also displays a piece of brief information about your storage, be it internal storage or external storage. You can see this information on the bottom of the main screen of Files.
