4.2 Application Security Features

4.2.1 App Lock

The App lock not only protects the security of application data but also prevents the private information in the application from being seen by others.

MIUI users can enter the "App lock" module through "Security" and choose from a wide range of options (Patterns, PIN and Password) for the application. Through this module, users can set the app to either lock after exiting the application or to lock one minute after exiting the application, and then verify the App lock when opening the application again after locking the screen. To increase the convenience and security of unlocking, MIUI adds fingerprint biometrics and facial recognition unlocking mechanisms.

4.2.2 Blocklist Setting

MIUI's blocklist settings can provide users with comprehensive blocklist setting functions, which can effectively intercept unwanted phone calls and text message spam such as advertisements, sales promotions and real estate agencies and the like. Users can quickly add phone numbers from their recent call history and contacts to the black/white list. Users can also add regions to the black/white list to intercept phone calls and allow known numbers. The updated real-time yellow pages database provides users with accurate yellow pages information for numbers and prevents users from being disturbed by calls from unknown numbers.

MIUI provides a variety of interception rules that users can manually configure as needed. These configurations can be backed up to the cloud to perform functions such as cross-terminal synchronization, among others:

• Black/white list: Allows whitelisted numbers while blocking blacklisted numbers.

• Unknown number: Intercepts calls from unknown numbers.

• Call forwarding: Intercept forwarded calls.

• Smart interception*: Filter unwanted calls and text messages spam via the yellow pages database and intercept engine.

*Note: The smart interception feature is available in India only.
