How to Easily Clean up Junk Files on Android By Using Mobile Apps

There are some fantastic apps in Play Store that will root out and remove all your junk files, folders and other content. Most of them are free but may include in-app purchases for premium features. Usually, basic features like junk file cleaning are free. Here are some of the different types of junk files that can be weeded out by a typical mobile Android cleaner app:

* Temporary files

* App cache files

* Files that haven't been used for a long time

* Residual files left over after apps are uninstalled

* Browser cache files

* Language files

In many cases, large files and app cache file cleaning will be in a different category from junk files, but that just depends on how the app finds the junk. The basic approach that all apps use is to first scan your entire memory for all files. They will then identify anything that’s not required for the normal working of the system and the apps, and tag them as temp, cache and so on. The third step is to allow you to review the junk files and display the total memory space you can save by deleting them. Some app cleaners will also let you clean RAM by killing background processes, which is another thing that tends to slow down your Android device over time.

Although mobile apps are more convenient, they are generally unable to completely delete data in an unrecoverable manner. For that, you'll need a robust desktop Android device management software application. The way they work is explained in the following section.

How to Clean up Junk Files on Android Using Desktop Software

With most desktop cleaner apps, junk files are just one type of unnecessary files that you can remove to free up space on your device. Such software often contains additional modules for erasing, data backup and restoring, system recovery, transfer, switching and even rooting. Whatever software you choose, make sure it has a good reputation in the market and has been around for a few years. In this part, we will take FoneMoz Android Eraser for example.

Step 1 – Download And Installation

Step 2 – Plug Android Phone into Computer

Step 3 – Scan Samsung Smartphone

Step 4 – Clean up Junk Files

The more robust applications in this category will be able to completely delete all junk files, and you won't even be able to recover them with recovery software. That's why desktop applications are generally better for device memory management in Android. Normal deletion retains the data, but a thorough erasing process will overwrite it multiple times so nobody can retrieve it. Even your junk files are private, so this is the recommended option whenever you do your Android spring cleaning.

At times, factory reset is the final option left to format your device content and start over again. Again, doing a factory reset will take your device back to zero as all the settings will automatically get reset to by-default. That is, your Android device will be set to standard settings.

However, using a more recent Android device or an updated version on your device might keep the latest upgrades. For instance, if your device was running on Marshmallow or Lollipop and later got updated to Oreo, then your phone will continue with the same even after the reset.

This feature's primarily used for flashing ROMs on devices but equally handy for older devices. Plus it's a good idea to back everything up before doing this.

Here is what to do to restore your Android device to default stage by factory settings. Tap on 'Settings' and hit on the 'Backup and Reset' option. If you don't find this option under Settings then check it in the Additional Settings.

Well, it is that simple to clean the junk files and data from your Android system. However, if you are a beginner, then it is best to go with the second method to be on the safer side.
