After I paired the keyboard with my Android it worked immediately.
However - when I wrote the Z was written on the keyboard as Y.
and Y written as Z. and yet so many others Fehlbelegung.
This confused me at first.
Then I on the Logitech website found that it can herungerladen the "driver" in the Play Store, entitled "Logitech Keyboard Plus". A small tool which allows you to configure the keyboard.
And thus also customize the keyboard layout to the desired language.
One shortcoming (a star deduction):
The ON / OFF switch is on the bottom next to the battery compartment.
Blind I never ertaste the switch. I always have to turn over the keyboard.
The keys for couples are also mounted at the top - then why not the ON / OFF switch ???
All in all a great product!
