Old mic issues with pixel. Solutions?

[tt_danielfurieri]

Guys,
I'm having the mic issues with Google pixel, try everything, even replace the phone with Google, but I'm in Brazil and have a cracked screen, so it's practically impossible to use the warranty.
So I'm looking for possibles solutions, or I will see my expensive cell phone be useless. Does anyone know or saw in foruns a possible solution for mic problems?
I work in a oil platform, and the phone is in air plane mode, just with WiFi turn on. The mic is working with no problem for 6 days uninterrupted. If I was home, this would last for just 2 hours at the most. Is there a solution? Deactivate Bluetooth or something like it?

I'm desperate. Can anyone help me?
Thanks a lot!

I doubt Google won't fix the mic issue because of your location or cracked screen.

Yeah, I call Google and stay like an hour with them.. They told that the cracked screen make me loses my warranty. Something that is occurring on several phones, because the screen they will not replace it.
There is some channel that I complain about it?
