i'm at a standstill on deciding which phone to purchase next. i currently have the pixel 6 and i'm actually disappointed with it. the phone is too buggy and im tired of google's bs.
i've had issues where my screen goes dark during calls and i can't wake it up, when calls come thru, i don't see the caller id until like 3rd or 4th ring, people can't hear me when on speaker, it chooses what volume different apps chime in at ( this has gotten me in serious trouble with alarms)
Good luck! I'm on Calyx but I know plenty use graphene as well.
That sounds like a bit of a buggy mess you have had. If you don't feel like swapping OS, you may be able to fix the issue just by downloading a different phone app.
