This post really shows how old I am, because I immediately thought "does anyone actually compose on a mobile device?" The experience is so bad I limit my own mobile compositions to message responses like "k" and "lol".
I wrote this comment on my phone and it was an awful experience 🙃. But hey, at least my keyboard app suggested a silly emoji...
I'll continue to do my "real" writing on my desktop for now. Integration apps like KDEConnect have been enough for me to get by, but they aren't perfect either.
I've got a folding phone so I can unfold the screen into a small tablet and it's so much easier to type on it.
It would be nice if Samsung would put decent cameras in the fold, but I'm still going to get another one because I'm not going back to a teeny tiny screen.
I tried the F(x)tec Pro1x earlier this year in the hopes that it would unlock some writing productivity for me with its built-in keyboard. I managed to get one really cheap, but it (like many other "exotic" phones) had so many cellular network connectivity issues that I gave up. I now have a Samsung Galaxy A54 with GoogleFi. The typing experience sucks but at least I can make / receive calls...
Don't import phones it's a waste of time, particularly if you're importing into the US because for some reason the US has this weird standard that nowhere else uses, because reasons. But that's just an issue with imported phones in general.
