CM Locker is a free personalization tool developed by Cheetah Mobile which allows you to secure & boost your device. One of the most powerful features of this application is the security function.
CM Locker is that you can secure your device with multiple passwords and if someone tries to use your smartphone it will automatically make a snapshot.
We at Techforpc think that this is an amazing application and we highly recommend it. You run CM Locker on your PC by simply installing BlueStacks.
