How does Huawei 4c mobile phone encrypt SMS and qq?

Dear, I suggest you encrypt the application. Enter the desktop "Mobile Manager", click "More-Application Lock", set the password according to the prompt, and select the application you want to lock, such as SMS, QQ, etc. Similarly, if an application that has opened the application lock wants to release the application lock restriction, enter the "Mobile Manager", click "More-Application Lock", enter the password, and turn off the application switch that you want to unlock.
