Suddenly can't hear people on calls. Speakerphone works

[resarfekim]

Just noticed I can only talk to people on speakerphone. Off speakerphone, they can hear me, but I can't hear them.
If there some setting somewhere I might have tripped? Restart doesn't help.
Pixel 2 XL, stock, June update.

Thanks for any suggestions.

Wiping helps. My friend experienced a similar issue after an update. He then did a full wipe/factory reset and things were back to normal.

I had the same problem after I installed Android Auto, I think it was stealing the mic. Uninstalled and no more problems.

I wound up wiping, and that fixed it.
Didn't get to a chance to try uninstalling Auto.

Thanks!

That's okay, I had it bass ackwards, people were unable to hear me, you were the other way around.

Solved!

Phone, Settings, Accessibility, Hearing aids - was enabled!!

Ugh, 2 weeks later, and my speaker stopped working again! I don't think I've made any changess recently.
I installed one of those phone-testing apps, and the speaker doesn't work from there either.

Any idea what I can try? I don't want to wipe my phone again (and every 2 weeks).

*update*

Ok, google support was of course no help, except to say that I should factory reset again, and if the problem reoccurs, then we'll talk replacement.
So I did the reset, and like magic, my speaker works again. There has got to be a better way. Any advice would be much appreciated!

I'm on full stock, latest firmware.
