Hey!
whe I call with my earphones/mic plugged and lay the phone on the table, it switch to loudspeaker. How can I avoid that? Can’t find any setting. I’m on 3.1.4-a15 on a Pixel a7.
I could be that the earphone/mic jack has an issue. When you remove the jack the phone will switch back to either the ear speaker of the loudspeaker depending what is selected in the phone.
If the jack has an issue, laying it flat may cause it to connect or disconnect. Either the jack is dirty (oxidized) or there is a cold solder joint in the earphone jack or even dust or lint in the jack.
you’re right. It is not the highest quality usb-c-jack but it seemed to work. The thing that made me think it was a feature is that it is perfectly stable when listening to music. It only disconnects with mic/voice.

That is my mistake the Pixel 7a doesn’t have a 3.5mm jack, that is what I was referring to. But in the case of audio over USB C, USB C does support analog audio so it could be the connector or cable. Try another USB C audio device to narrow it down.
