Videoformat at ROCK PI 4C on Android10 with Raspberry Pi camera V2.1

The Camera (raspberry pi V2.1) uses just a part of the sensor at video recording. Thus just a small field of view is recorded and the video has a very bad quality. I´ve used android standard camera app, and tested also other apps.

Taking pictures is fine. It seems that the whole sensor is used for taking pictures but not for recording videos.

How can the camera video function be adapted, that the whole sensor is used and the quality is fine?

Thanks in advance!
