I dunno. My pixel 6 has been awesome since scrubbing the google out of it with Graphene. Great signal antennas and pretty fast processor for being 4 years old. GrapheneOS is what makes an Android work, not the hardware. The hardware is roughly the same.

When I switched to lineage it pretty much fixed the connection issues but it still loved to overheat when it was above like 30°C outside. When I end up getting an android again it will be from Nothing Phone or something. Ideally, mobile Linux will evolve. Interested in the Librem 5
https://liberux.net/ seems to be the next iteration. My only issue has been the lack of hibernation for a linux phone OS kills the battery. Either way, I have not had the issues you are talking about with grapheneOS but maybe your specific software stack introduces that.
Right I heard about this a couple weeks ago but I forgot about. I hope it works out. I might fund it.
The thing is that iOS does what I need. I don’t need my daily driver to be able to install apks or do all the other power user stuff. I’ll only switch either when I get bored of iOS or when there is an alternative that actually makes me excited (like the liberux)
It's not the apk usecase, it is the proprietary ecosystem solidification and future dependence that you are fostering. The Apple ecosystem will make certain features so important to you that you won't want to control your own software or hardware. Then you will be another one in the flock. Open source often takes longer but doesn't force control.
