-   Secure file access is supported, which means that a file object can be converted into a URI and a URI can be parsed to open a file.
-   PIN authentication is supported for the distributed device management service.
-   Relational databases and distributed data management are supported.
-   The ARK JS compiler toolchain and runtime are supported, and the OpenHarmony JS UI framework application development and running are also supported.
-   Remote binding of a Service ability and cross-device FA migration are supported.
-   Application pub/sub and redirection of application notifications are supported.
-   The input method framework is supported, and basic English letters, special characters, and digits can be entered.
-   The camera module supports preview, photographing, and video recording.
-   The CS basic call and GSM SMS capabilities are supported.
-   The timer capability and the scheduled time zone management capability are supported.
-   In the distributed networking of standard-system devices, permission verification is provided for applications to access peer-end resources or capabilities.

The feature updates for the mini and small systems are as follows:

-   The lightweight distributed capability is enhanced so that the ability on a standard-system device can be started from a mini-system device.
-   The DSoftBus capability is enhanced to support transmission of authentication channels for device binding.
-   The lightweight globalization capability is enhanced to support 31 more languages.
-   The permission attribute field and its write interface are added for the mini system. Upper-layer applications can use this field to implement related services.
