Yippee!!!
I have got it now! But I really don’t what was wrong with my last configuration.
I went out from the settings and back again, and the setting was wrong. So I put it in again und now it works!
What I have learned about hardware keyboards and Android:
- The keyboard has to be connected to the device, otherwise you can’t set up the hardware keyboard setting, because there is no physical keyboard at the phone setting without!
- The Android keyboard app (ASOP) at settings\apps\ has to be activ. If you deactivate this app, you can’t set a language for the physical keyboard at ‘Languages & input’.
And thanks a lot for your help @AnotherElk! I would not have got it without your assistance and endurance!!!
