I’ve looked at a few on fdroid and they all seem like they aren’t being maintained anymore.
Edit: I’ve spent the past day trying most all of the suggested keyboards here and I think I’ve landed on either Unexpected Keyboard or AnySoftKeyboard. Thanks for all the suggestions. Thumbkey is quite the thing to get used to.
Is this available on F-Droid?
It came stock in crDroid 10.
For previous AOSP keyboards, someone has extracted the .apk and posts it on apkmirror
They may also be referring to this but I’m not certain.
