DJI mini 3 Pro camera glitching


I am facing a problem where the camera feed on remote and recording(i checked later on the sd card) of my mini 3 pro is glitching periodically either every 1 sec or every 2 sec. Sometines it stops, and then starts again after some time. I am attaching a video link to this post.

I tried various things like updating firmware, changing batteries, resetting and calibration.

The video is taken when the drone was on ground but the issue remains the same even when in flight.

Please help me out on this issue.

Thanks and Regards
