Question:
The in-built app lock for individual apps doesn’t work, after locking the app in privacy settings, when I try to open the app for which I’ve set up a lock, only for the first time it asks for a lock code (pattern set). Subsequently, the app opens up without asking for a lock code (pattern set). Can you please help ?
Answer:
The privacy protection will prompt you to draw the unlock pattern for the first time you launch the protected app. Subsequently, the app can be opened without the need of drawing the pattern as long as your phone doesn’t go into sleep mode.
If you would like to lock your app immediately after use, the best way for now is to press the Power button to put your device into sleep mode.
While this isn’t documented anywhere, I’ve tested and confirmed that this is how Privacy Protection works in both the MIUI V5/6.
