Same issue here.
Has anyone tested if it is worse on Wifi or mobile internet? Or on VoLTE vs old-style calls. For me the issue strongly varies from day to day and location to location
Bro I have tried everything.... Testing and designing is what I do for a living....... And the only factor causing the s#itty sound quality is Oxygenos on the OnePlus 7T . Btw today checked it on my friends' iPhone10 and LG G6. They all sound amazing on calls.
Also chk my previous comment, they also sound much better when calling with a $70 phone!
