Cheetah Mobile and Samsung Collaborate to Enhance Mobile Security and Innovation

Mar 2, 2015

BARCELONA, Spain, March 2, 2015 /PRNewswire/ -- Cheetah Mobile Inc. (NYSE: CMCM, "Cheetah Mobile"), the world's top developer of mobile utility apps, today announced a partnership with Samsung to enable a best-in-class mobile experience for millions of Galaxy users around the world. As the first step in their cooperation, innovative features from Cheetah Mobile's top-rated security application Clean Master have been embedded in Samsung's new flagship Galaxy S6 and Galaxy S6 edge smartphones to provide custom "Powered by Clean Master" junk-file cleanup.

"We're thrilled to join forces with Samsung to help Galaxy S6 and S6 edge owners get the most out of their new phones with the 'Powered by Clean Master' feature," said Sheng Fu, CEO of Cheetah Mobile. "Clean Master's distinctive qualities have made it the No. 1 app in Google Play's Tools category across over 50 countries, the top choice for hundreds of millions of Android users, and now a valuable partner for Samsung's mobile phones. Samsung's passion for creating a simple, secure and seamless experience aligns closely with our own, and we look forward to a mutually beneficial long-term collaboration."

The "Powered by Clean Master" functionality in the Galaxy S6 and Galaxy S6 edge, both of which were unveiled at the 2015 Mobile World Congress, is the result of joint meetings across four different countries and extensive testing by both parties.

As Android users add a growing number of apps to their phones, all of those apps generate gigabytes' worth of junk cache files and contribute to insufficient storage errors. Clean Master consistently helps first-time users get back more than 2GB of space. On average, Clean Master frees up 30% more storage than similar tools.

Clean Master invented an advanced 'Cloud + Manual' cleaning system capable of completely analyzing the hundreds of thousands of apps that phone users install every day. Clean Master also includes proprietary multilayered technology that prevents important files from being mistakenly deleted, so users won't lose their precious photos, videos and files. Privacy Protection, another popular Clean Master function, allows users to browse and chat online without fear of their private information leaking out.

Cheetah Mobile's partnership with Samsung represents the culmination of the company's explosive growth over the last few years from a small startup in Beijing to the global leader in mobile utility applications. Cheetah Mobile was named 2014's 'Best Android Security Product Award' by the AV-Test security institute, and its flagship app, Clean Master, is currently the No. 1 app on Google Play for boosting smartphone performance. In January 2015, App Annie named Cheetah Mobile the No. 3 non-game publisher in the world for Android and iOS, behind only Facebook and Google.
