Microphone Issue when using Samsung Camera

[Members_Ku4qy5L]

Hi there, I was wondering if anyone could help.

I've just purchased a refurbished Samsung S20 Ultra, and I have ran into an issue with the Microphone on the Camera App.

When recording a video, the microphone detects my voice and other sounds around it, but it also picks up a static noise, with sort of beeping noises? When I speak, it fades, but then starts again when I'm quiet. It's also very noticeable when re-watching videos. I put my JBL earphones in and tried to speak and record a video, but still then I encountered the same issue. I noticed I could hear it predominantly in my LEFT earphone, rather than my right. I feel like it's software rather than hardware, but I am not 'clued up' on phones.

I have tested the microphone on Samsung's Voice Recorder app, and it's crystal clear, with no issues.

I have attached a video of me banging on a glass, you can hear the noise in this video. Wearing headphones, you can hear it through the Left speaker, but not the right!?

Please could someone help me, as I bought this phone to record videos and use the camera, and it's driving me insane!

We will need to wait until your attachment is checked by the Samsung Community Team before it's allowed @Members_Ku4qy5L 

I note you say the phone is " refurbished  " which leads me to maybe consider the phone is faulty in some way 🤔 

In the meantime please also send your feedback via your Samsung Members App too.
