Although as an antivirus, this part of the app isn’t bad per se, it isn’t the best either. The app also comes with an Anti-Virus, which is possibly the app’s only redeeming feature. The Junk Cleaner can easily be replaced by emptying your phone’s cache in the settings, ironically, saving you the resources Clean Master would otherwise be taking up. With the once core feature of the app now pushed to the back, are the new features worth downloading the app for? I personally would say otherwise. It appears this common criticism has led Cheetah Mobile, the company behind Clean Master, to revise their marketing of the app and list the “Boost Mobile” feature as second-last in the app’s page on the Play Store.
Of course, freeing up RAM on a Linux based operating system doesn’t accomplish anything, since the Linux Kernel makes a special use of RAM not being actively used by storing cached processes in it, for quicker access later.
The app promises to increase the performance of your phone, and in the past mainly explained it by “freeing up your ram”. Yes, I said before it was created, because to me it’s just a more commercially successful rendition of the same app that has existed since before even Android did. Overall Opinion: I’ve known about clean master since possibly before it was even created and never cared to try it out until I decided to review it.
