There is 2fa and other such services that I have to have access to. Worst case, I cant get into accounts and such.

That's my main concern too.

Here in Denmark, the MitID authentification app is completely integral to functioning online, and last I checked it doesn't work on GrapheneOS, so /e/os is probably not likely either 🫤

I have a FP5 and a similar problem to you. My FP3 before it died on me so it's not much help.

I'm low key planning to find a second hand FP3 and use it to experiment with Linux until I find there are no big problems with using it as a daily driver. In practice I don't really have enough time to put into it so I'll probably keep on using /e/ for the forseeable future.

That's fair. Which models did you have? I had a couple problems with the earlier Google Pixels, but I've found the later ones have really ironed out their hardware problems.

I think your main problem is going to be finding phones for cheap that also work well as Linux phones. I think the lowest-effort options like Pine phones are gonna cost you more. But I wish you luck.

get the new Jolla Linux phone.
