Starting ~4 months ago the 'phone' part of my Pixel 3 has been performing poorly. Sometimes my phone will ring and swiping up won't answer. Then I get a voice telling me to say "answer" but it still won't pick up. Sometimes when I call people I can hear it continue to ring even after the other person has answered. It's like the app is not 'synced' with the call. Rebooting the phone helps but for not very long. I can't believe I'm the only person with this issue so I hope someone fixes it soon.
