I just got the feedback from several people that they hear me very muffled/bassy via Telegram/WhatsApp Video Call. I used the recorder and took a sample to verify the issue. I think compared to my OnePlus 6 the microphone quality is very bad. I already had issues on my OnePlus 6 that used the wrong (rear) Microphone in Teams for conferences and I'm kind of disappointed there is an issue with the mic again. Did you test your mic and what is your experience so far?
