Increasingly unhappy I have been a long time fan but not now. This app while telling you to uninstall to create room is pushing other apps...theirs and others! This is constant. I would need to delete less junk if I did not have this app.

Michael Boyd

Best booster of all For both junk cleaning and power consumption savings, this is the best app I have ever used. Doesn't bug you all the time... Warns as needed... Seems to just be all the time keeping the phone humming at peak performance. Highly recommended

Love this app but something on new update Before we were able to hide the ad on charge master for 7 days. The button to hide doesn't appear anymore. Some ads are really inappropriate. Would be nice if we could hide the ads even if it is for a day or 2

Cleaners all have draw backs CCleaner was very good but can't run properly on my phone unless you do a manual process. This fast clean is simple and it really works! Just close the ads and ignore them and it's fine.

Andrew Wells

Annoyed Once again CM's anti virus checker is trying to force me into downloading the Whatscall app by telling me that my phone is at risk if I don't install it. I don't need What'scall as I already a good call screening app which doesn't include having to buy credits to make phone calls across the Internet. Please kindly stop this kind of "strong arm" advertising.

Kathy C

Uninstalled Now I remember...I had this once before and in a weak moment I reinstalled it. While the concept is good I got tired of my phone always opening up to yet another "Install Me" or "Fix It" ad. So irritating so off it goes against. Let me know if you ever fix that. I'm not against ads but not always in my face.

Hi. Sorry for the inconvenience. It is good question for us. Boost your phone by closing applications. But some applications are auto start on background. Either choose Battery Status or Phone Temperature; both stop the auto starting applications. Any question please feel free let us know via FEEDBACK. Many thanks!

Applock gets stuck Sometimes applock gets stuck or hanged... Team should find a solution for it and add the previous option to make a backup of apps which are in the phone to cover all kind of things you want to give to users...

Anonymous Nieto January 10, 2017

Took my chances and disappointed Well rated this app a five star app earlier this morning I truly dislike this app. It started to make my phone over heat and run slow once I downloaded it. I will stick to the 6.4 star app I am already using before this one.

Shivaji Mukherjee January 10, 2017

Useful but now it's became slow and try to push other apps It's useful for clearing garbage in your Mobile like temp file and cache. It also identify apps which are restarting continuously. I find it useful but now it become heavy and slow and it try you to install other apps and try to show advertisement at every opportunity.

Paul_Melvin _ January 9, 2017

Clean Master One of The Best! I've been using Clean Master for a few years and has NEVER failed me in all these years!... As I run Clean Master, I'm VERY careful NOT to click on the items that displays "Contains Ads." That sort of defeats the purpose to get rid of junk! Lol... Just be sure that you have included the files backed up to either Verizon Cloud or Google Cloud... BEFORE running Clean Master!!!!... Then I reboot my Cell (Note 3)... yes it is very old, but still works VERY fast aster using CM! THANKS CM!!!

Margaret Benzie January 9, 2017

MagsB Keeps my phone junk and virus free and lots more great aspects like freeing up space and cooling down battery when it gets overheated from time to time. One thing now being bombarded with ads from other APS saying my phone has no space and trying to fool me into downloading them - making out they're Cheetah with a logo almost the same. HOW TO STOP THESE !!!!! Why don't you respond !!!!!

Cheetah Mobile January 9, 2017

Dear User, Clean Master is committed to fighting against the pop-up of misleading ads. please send us screenshot and URL of the misleading download to [email protected]. We will deal with the problem immediately.

Animesh Guha January 9, 2017

Very useful I liked it very much. Very Useful... Cleans up all your waste / temp data.. Gets me loads of space, all features are available in 1 app.. I Love it

Astral Lite January 9, 2017

The One & Only Clones of this app have made it as far as to become masked spyware with limited features of their class. It's truly an honor to have this 'original' app around. Please, keep up the good work.

Cheetah Mobile October 18, 2016

Dear Leif, thanks for your feedback. We've taken them down seriously and we'll talk about your suggestion soon. Thanks.

Nikki Csl January 10, 2017

Wish I can rate twice, this app deserves to say 5 stars Every phone I get this is the first thing i download. I tried other apps out but they only pretend to work. You can feel it working when you fix your battery temperature cause it cools down after. Can't beat that

Brenda Mccoy January 10, 2017

Hate the pop ups every few minutes. It should be daily or twice daily, but love the job it does.

Angie C.W. January 10, 2017

Fantastic app aside from When my phone is charging this app brings up a second lock screen, where I'm unable to change anything in my notification bar. Aside from that I absolutely love it, but that feature is very inconvenient.

Peter Pistolas January 9, 2017

Not sure that it's working. How do I know that this App really doing its job? It keeps freezing and not responding. It hasn't sped up my phone. Constantly gives me this big overheating warning then cools it down a whole 5°. App is supposed to fix phone issues. But then it recommends me to download all these different App's for different problems. I would have downloaded about 4 other Apps by now if I followed recommend Apps. Seems like a scam. Any body else having this/or other problems?

Cheetah Mobile January 9, 2017

Dear user, Sorry for the bad experience during using our app. Have you set the notification in setting? And please go to Me-Setting-Notification setting-Turn off the CPU Overuse Reminder. Any question please contact us via Feedback. Thanks!

diana clarke January 10, 2017

Infomercial This app is like an infomercial. It has plenty of suggestions of apps I "need." As far as "cleaning" notifications, it actually gave more notifications than I was getting before installing it. The cure is worse than the disease, it seems. The graphics are cute. If I weren't such a skeptic, I'd think it really was cleaning and boosting and cooling. I'm not convinced. I'm tired of its endless prompts so it's going away. Maybe I'll try it again in the future and like it better.

Melinda Johnson January 10, 2017

Awesome app!! I had a question about the app needing certain permissions and they answered my question in a timely manner and in a way that could be understood. Great customer service and an awesome app! It's very easy to use and does a wonderful job! Thank you for such a useful app!Keep up the great work !!

Fernando Jacob January 10, 2017

Junk Notification Bug After every restart junk notification cleaner turns on automaticly wich i dont want to happen. It blocks all notifications and i dont see important stuff anymore.

January 9, 2017

I get several notifications everyday to clean device. Push a couple buttons and it's done! I use to get messages that I had no storage space. After installing the cleaner I no longer get those messages. Love it!

Linda King January 9, 2017

This tool does it All! No need to have 2 or 3 other apps, everything from virus protection to cooling your device down. Performance is excellent.

Marshall Hale January 10, 2017

For the whole family As soon as anyone in our family gets a tablet or a phone clean master is the first app to be put them . It's easy, fast, and helpful. Even my 2 yr old cousin uses it on her tablet .

Jeffrey Kohn January 9, 2017

Good for battery life Tested a ton of these kind of apps and this is the one I keep coming back to. Gives me the most options. Excellent app and get Battery Doctor too. They work very well together!

January 9, 2017

Iris.Ramadan Very good so far. I don't like to say the apps are good sometimes because it back fires and things start not to work as well.

Ruff Riders January 10, 2017

Issues Battery saver/1tap-Hibernate constantly gets stuck on Force Stop screen. A lot of updates but this is still not fixed yet!

MAX ON GAMING January 9, 2017

Very Useful It clean all junks and my phone work faster and faster i like this app I m very happy from this app 5 stars to cheetah mobile

Amanda Bruce January 10, 2017

Great app! This app has protected my phone from multiple viruses, as well as cleaning all the crap that usually uses up your storage. I always get it when I get a new phone. ⭐⭐⭐⭐⭐

Mert Musa Temel January 10, 2017

Cok İyi Cok kullanisli ve ise yarar bir program. Her telefonda bulunmasi gerekir. İsinize yaramayan dosyalari ve artiklari bir tikla silebilir ve hafizanizi artttirabilirsiniz. Ayrica hizlandirma ozelligi de bulunuyor. Bence 5 yildizi sonuna kadar hakediyor.

Navjot Singh January 9, 2017

Its just okay It used to be good but now a days instead of making my phone fast it is slowing down my ph. So please do something . I dont want to uninstall it cus it is one of my best app so please do something. Thanks...! LOoking forward to see the new update .

Cheetah Mobile January 10, 2017

Dear User, Thank you for the feedback. We are aware of this issue and we're continiously improving Clean Master's performance by making it consume less and less resources and run more and more faster. You may also try CM Lite version which is much smaller and faster, should be useful in many occasions.

January 10, 2017

I like the cool down feature My phone often overheats and slows down, so the feature where you can lower the temperature really helps.

Andrew Gallese January 9, 2017

Always find room. Whenever I'm in a jam and need to find space on my cell, I run junk file scan. Works great!

Matt Ernst January 9, 2017

This app is good Helped clear up so much useless data on my phone. Also really helps with cooling down the CPU. Very helpful.

Debra Gonzales January 10, 2017

Got a new phone and still Very Clean This is the perfect app for an Android no matter what Android you have, I even told a person that has a Jelly Bean System about it, don't know how that went.

Johnny Miller January 9, 2017

It keep telling to get more apps then it do not want to work half of the time

Cheetah Mobile January 9, 2017

Dear User, We were hoping users could enjoy a wonderful mobile life with different type of tools and content like news, games, etc when using Clean Master, apologize if you feel it's bothering sometimes, we will keep improving the content so you can feel comfortable with these recommendations.
