if I understand correctly there is no way to make FOSS AA (protocol itself is not open unless reverse engineered). There needs to be separate implementation like AA / CarPlay and headunit needs to support it. Current best case scenario is miracast supporting headunits (but this is one directional)

Check flokinet.is In general islanding provider should have features you are looking for, I like flokinet.

I like my librem5 (hardware, feel etc). Software is obviously yet to catch up (from my perspective).

I just wish as a company they upgrade (forthcoming) their communication

let me check this, thanks

Have u tried soulseek in that case? U can find all music lossless.(podcasts etc I still can't find there). nicotine+ is pretty good client for soulseek.

Oh I just use swipe actions. Tap on comment and swipe left/right, there are 2 actions on each side depending on how much you swipe.

Also voyager was the only client allowing me to increase the font size (when I started using lemmy on phone)

+1 for floris, it's the only keyboard with glide typing and themes are super good.

Have you looked at proton mail and drive?

Yes, also generally I donate different project every 6 months (instead of recurring payment to one project).

Are u trying to install on x86 or ARM? ARM has images u can use. As for x86 I didn't find distro with out of the box bigscreen configured, however there are AUR recipes - makes it easy to use it on Manjaro.

I've nano g1 and lilygo echo, both are prebuilt. However I agree bit too big, I'm looking for something without screen and small (there are devices but as you mentioned those are not prebuilt)

Can u check https://meshtastic.org I am looking for something similar and came across this, however I'm not entirely sure yet if this works as I think it does.
