Edit: SOLVED. It turns out, I had uninstalled the system package com.android.inputdevices , which is used to locate available keyboard layouts.


This is on a Samsung Galaxy S23 using Heliboard and Simeji as software keyboards. Samsung’s keyboard is uninstalled. On my Galaxy Tab A9+ with the exact same configuration, I am able to set the default keyboard layout…
Any ideas?


Doors the tab have the Samsung keyboard installed? It might be required.
Oh, same config as the S23: no Samsung keyboard. I did try to reinstall it just in case, but that wasn’t it.
Same android/oneui version?
