I'm not sure I'm ready to go all "lineageOS full degoogle" on my phone because some rather necessary day-to-day apps for me will freak out if I have root, let alone a modified OS. Buuuut GBoard has gotten right in my tit, and now they're offering nightmarish AI generated emoji and I'm like "NO". So.
I don't really care about predictive text or swipe-typing or any of that stuff, I mostly just type normally.
The only nice-to-haves that might entice me would be support for one-handed mode and a configurable keyboard layout.
Gboard runs OK without any permissions, so if you don't find anything good enough, that still could be your solution.
I tried many other options but haven't found a bilingual swipe keyboard as good as Gboard unfortunately. I just gave it network permission to download dictionaries, switched off all permissions, and it's running smooth since months now.
