Any update on this bug?
I tried turning off Google assistant and then updated to the latest available ROM but nothing changed, I can't use my Max 3 as a phone simply because the mic is not working when on call. It works when recording or testing it otherwise. So it is definitely a soaftware problme which I believe many other have
Already sent report to the Mi devs
If that is not addressed in a proper way this will definitely be my last Xiaomi device
