Hmmm, if you do not want to use Pixel for hardware issues, Fairphone is probably not going to be your best replacement. The Fairphone 6 has suffered from an issue where they die during charging, even on brand-new devices. People also encountered issues like the volume buttons breaking after just a few weeks/months (for which they don't sell replacements). Replacement of a FP6 under warranty often takes 1-2 months. And you cannot repair it yourself if they don't sell the parts that most commonly break (logic board and volume buttons).
I wish Samsung made an S-variant (or A5x) that passed all the GrapheneOS requirements. It's really stellar hardware (if conservative). I know it will never happen, but one can dream I guess.
Sounds like I've been very lucky with my Pixel 4 and 7 that I haven't had any hardware issues while running GrapheneOS.
Now: just overpriced crappy Google hardware that lasts 12 hours because of AI and who knows what else they shoved on there.
And nobody else makes anything close to what Fitbit made...
