There are so many little things I want to buy just to put Linux on them lol. I've been eyeing the Fairphone 5 because the creators merged all the drivers for it into the Linux kernel and it(along with the Fairphone 4 and hopefully 6 in the future) is fully supported by Ubuntu Touch, being one of the few phones where it has a 100% support rating. Well, excluding GPS and VoLTE(although they're issues on all supported phones), but GPS just requires you to restart whatever app you're using and then it works and VoLTE has a patch incoming to fix it.
It'd be so fun to daily drive a Linux phone, since all I do on my phone is call and text and maybe browse this place and Bsky, the last two can be covered by Waydroid, which is built into UBTouch.
