There are a lot of Android devices out there and it’s hard to keep track of all the junk files that are created by them. This is especially true if you’re not a computer expert and don’t know how to clean them manually. There are a few ways to clean junk files on Android devices, but the best way is probably through the system settings. You can find these settings in the Settings app on your device. Once you’ve found the setting for “Junk Files,” you’ll need to select “Remove All” from the list of options. This will remove all the junk files from your device. If you want to keep some of the files, you can choose to store them in a specific folder or file location, but it’s best not to do this if you don’t have space for them.
