On Android device, junk files (cache and residual files) can build up over time, filling up space and even slowing down your device. Cleaning those junk files can free up a great amount of space on your smartphone and speed up your Android device performance.
To clear the cache, you can go to the Android application manager, click on the app from the list, and then tap on ‘Clear cache’. However, if you have many apps installed, then this will take a lot time to clear it manually.
Fortunately, there are cache cleaner apps available for free on Google Play to help you clear away those junk files quickly. One of the best among them is Clean Master. This app has been downloaded by over 50 million users worldwide. Clean master is an all-in-one cleaner app on android that lets you clear app cache, deletes junk files, search history and uninstalling apps. Clean Master also works as Task killer which boosts RAM to improve your device performance and save battery power.

In the junk files section, you can delete app cache, residual files, ads folders, and obsolete APKs, which you can delete selectively or with an automated “Clean” option to get rid of all of caches.
The Memory boost section of the app allow you to close unnecessary apps that are running in the background, thus free up more RAM to speed up your Android device. Lastly, the app Manager feature lets you easily uninstall or backup your apps.
