I have the keyboard with a NotePro 12.2 of Samsung in use and it works flawlessly. Probably it is the tablet operating system that I need no helper app to put the keyboard in the dt. Layout mode, which worked flawlessly with the keyboard setting in the Android settings menu. The keyboard itself has a pleasant stop, the buttons are big enough and do not require extensive familiarization possibly a "normal" desktop keyboard. However, the keystroke is quite sensitive and I type still occasionally more keys at one time than desired ... The pairing works quickly and smoothly so far. The cover of the keyboard is sufficiently stable in order to include the above-mentioned large tablet in landscape mode, without bending from the weight - I would not have expected. The special keys of the top row of keys all work with Android. Only the Windows button at the bottom left is not as expected as recognized by Android home button and is therefore unfortunately no function in my setup.
