Clean Master reclaims Android device resources by cleaning caches, closing apps and processes, and deleting junk files, leftovers, and other unnecessary items. Kingsoft's app enhances your security and privacy by scanning for malware, cleaning logs and other records, and enabling real-time protection and safe browsing. Its App Manager can back up and uninstall applications. It does all that and then some for free.
Clean Master scanned our system when we opened it and displayed our free storage and RAM space on its home screen above four tools: Junk Files, Memory Boost, Security & Privacy, and App Manager. We opened the Settings, which include toggles for Notifications, Junk Reminders, Task Reminder, and more. Clean Master packs a lot of extras, including Fun Extras such as animations and seasonal events. We could also access more important features such as the Ignored List. We also suggest perusing the FAQ files, which serve as a manual to Clean Master's functions. Junk scans come in two types: Standard and Advanced. The Standard scan cleaned 94.8MB on the first pass. The Advanced scan identified nearly 2GB of potential space; but most of that was media files we wanted to keep. The Memory Boost tool analyzes running apps and processes and identified those we could close. Tapping any item let us stop an app directly or add it to the Ignored List; pressing and holding adds apps to the Ignored List, directly. One advantage of the App Manager is the ability to sort items by size, date, name, or frequency.
We're impressed by Clean Master's ability to keep unnecessary apps and processes from slowing your device and compromising its security -- and yours.

This SPAM provider constantly interferes with the use of my phone. Whenever I want to use the phone this garbage switches to its ad-screen and causes calls to be missed.
When I switch to email, this garbage constantly switches to its AD SCREEN and prevents you from using your phone the way YOU want - by not having to click on their ads in order to read the email.
I cannot count the times I have cursed this trash for interfering with my phone usage.
It is worthless if it interferes and hijacks your phone.
Avoid this spamware at all costs.
You will wake up in the morning to find Cleanmaster has transferred many gigabytes of data overnight. Especially bad if you have a limited data plan. I can't imagine any legitimate reason for the app to be eating data like this.
Is it a bug or is it a virus? Doesn't matter. Don't download it.
Deletes files without you knowing what's being deleted. It was offered as a companion to File Manager for Android, which is a pretty good product so far. After it scanned, it offered to clean up files, and SUPPOSEDLY was allowing me to choose what types of files. I was impressed with what I thought were the results - 66% free storage - until I found out it DELETED ALL OF MY AUDIO FILES WITHOUT MY PERMISSION. Thank God I have Wondershare on my PC and had those files backed up!
Last week this app began using massive amounts of data during the night when no one was using the phone and the app was closed. At 1.5GB at a time, over just a few days it used up and exceeded our data plan for no apparent reason.
If you have it, remove it immediately. If you don't have it yet, don't install it. There are other apps that do the same thing safely, including those that come with your phone.
