After sometime, Android smartphones become sluggish – the apps won’t open as fast, sometimes the apps show errors and die out in the middle, the browser takes longer to open up and so on. The common problem that is making your Android device slow is that many apps are running in the background consuming your device’s limited RAM and the storage of your device is loaded with junk files like browser cache and unnecessary APK files. The free app Clean Master can clean these junk files and close the unneeded background apps to make your Android device faster and cleaner.
The Clean Master app is available on the Google Play store website. When launched the app shows you four cleaning options – clean residual files, clean history, clean tasks and clean temporary APKs.
If you choose to clean the History, it will scan your device and show you a list of items related to your device’s cache as well as personal history items belonging to many programs like your web browser, Google Play store searches, Gmail, clipboard, etc. You can tap on the Clean button to get rid of the selected items.
On a typical Android device, the residual files can build up and occupy many gigabytes of storage space. In the Residual files section, it will show you all the residual files on your Android device’s internal storage as well as SD card. On my Asus tablet, it could not find any residual files.
The main reason for your Android smartphone becoming a little slower is the number of apps that keep running in the background. You can close all such apps under the Tasks section. It will show you all the tasks and the RAM that they are consuming. You can tap on Clean to automatically close them and free up the memory.
The more apps you install on your device, the more APK files are downloaded on your device’s storage. Although Android takes care of most of these automatically, but some of these may be left behind. In the Temp APKs section, you can view such APK files and delete them as you wish.
Conclusion: The Clean Master app can make your Android smartphone or tablet cleaner by removing the junk files & cache, faster by closing the unnecessary tasks running in the background and secure by cleaning app history.
