Why doesn't Huawei watch2 have a recording and calendar?

The watch can support recording/weather/calendar function after being connected with Huawei EMUI5.0 and above mobile phones. The recording method is as follows:

Click the recorder icon on the watch to open the recorder, click the red button in the lower left corner to start recording, click the pause button in the lower left corner to pause recording, and click the white square button in the lower right corner to end recording.

The recording will be automatically synchronized to the mobile phone via Bluetooth. You can't listen to the recording directly on your watch. You can open the mobile phone recorder APP, click the recording file, and find the completed recording on the watch.
