Screen Guardian

Save power, extend mobile key life and safe private experience of using phone with Screen Guardian. Features: 1. On your first setting, you should create a password. It shouldn't be too short and simple. 2. Remember this password, or you will not unlock your screen. 3. After your setting mobile screen password and screen is auto locked, this app will run and your mobile can enter into a safe lock status. 4. Want to unlock your screen? You should press the Power Key and input in your password correctly. 5. In case you forget your passwords, the only solution is that you have to uninstall this app. It's a secret between us. OK? Do not let the peeper know this secret.
