Galaxy A71 - random crackling sound when recording video

[Galactic1]

I recently acquired a refurbished A71 running Android 13 and OneUI 5.1.  I have the latest software updates installed. The handset was bought from a very reputable refurbed phone seller in the UK.  Everything about it is running perfectly, except for one quite major issue.

Whenever I record video, the soundtrack of the resulting footage contains random popping/crackling sounds.  I've tried recording video with the phone in Safe Mode, but the problem persists.  I've also tried re-starting the handset. Can anybody help me to resolve this?  I'm worried that I might have a hardware issue here.

NOTE: this only happens on video recording.  Audio files made using the Voice Recorder app are fine.

UPDATE:  I found the solution to the problem.

I realised that the popping noises were only occurring when the camera was being moved: panning/tilting etc.  I checked in the camera settings and found that I had Video Stabilisation switched on.  I switched it off.

Result: no more unwelcome noises!  For some reason I can't explain, the activity of the stabilisation process was generating the pops and clicks.  Hopefully this fault will be corrected in a future software update, but for now I'm happy to live without Video Stabilisation for the sake of clean audio. 👍
