What is clean master and what does it do?

Clean Master is an application that claims to optimize an Android device and speed it up by stopping applications running in the background, removing junk files from the device to save space, protect applications with a lock feature, protect your device with their proprietary Anti-Virus engine, and more. Theoretically, this should all boost the speed of your device and increase the overall performance of the device that has this application installed.

It is free on the Play Store if you would like to try it out.

Let me know if you have anymore questions.

You really should not use any cleaners, memory optimizers, battery savers, etc. Seriously. And never, ever install Clean Master or anything else by Cheetah Mobile!

It is recommended, not just for any cleaner, to read the access requirements of an application before installing it. Installing it would be at the discretion of the user. And you are right, most cleaners do not work as intended, so you have a point there.

The problems with apps such as Clean Master, DU Battery Saver and many others by Cheetah Mobile, DU Apps, GO Development and others go far beyond permissions or access requirements.

These are 'apps' that are not just ineffective, they are counterproductive, actually reducing the performance of devices. Often they hijack devices, throwing up scary notices, nag ads and forcing users to websites. Worst of all is what is happening with user's data.

There's a word for so-called 'apps' that do such things: MALWARE.
