"my foot itches, what's the best shotgun I can get to blast it off". this is like problemXY.
a 2-year old ex-flagship is a beast of a device. how do I know? because I run a 7-year old not-flagship and it's a beast. you tear google's shit out and keep using it. you can even keep using GCam with a "yeah-playservices-is-present" faker and then disable GCam's network access.
Google is an adversary. start treating it as such.
