Hi,
I can hear the other person, but the other person cannot hear me. 
This is happening to everyone who upgraded to Android 10 ASOP. 
When I use the headset or speak through the speakerphone, the other person can hear me.
This problem occurs using the phone, whatsapp and gooogle Duo application.

Does anyone knows how we can fix this problem?

Just for information: I had for a while a similar problem on my 5Z , but only when using WhatsApp for calls (the normal Phone App has always worked fine) . The problem was eventually related to the bad quality of the roaming service: selecting a different local service provider who could ensure 4G connectivity , the problem disappeared and also the phone calls via WhatsApp returned to their standard good quality. So, in my case it was not a specific 5Z phone related issue.
