Hi, I was using CM security application from last one year. I am going to share my real experience about this application.
CM security application is developed by cheetah mobile. I installed this app on 5 th may 2016 from google play store. I observed that various features such as phone lock, anti theft, anti virus, privacy lock, trash cleaner are available in this application. There is no need to download any other applications for these features after downloading CM security application.
One day my brother had tried to open whatsapp on my mobile phone. CM security captured his photos by front camera and sent me on my mail address. This application always keeps your data safe and private.
For keeping your phone safe this app is very usefull.
