The keyboard is very quickly recognized by the Galaxy sII and Android V4.0.4, ditto on my Nexus 7 Jelly Bean 4.2.1 You are asked to enter a code, you must type it on the keyboard itself and then input. The keyboard is paired. Then the connection is not made, you can not use the keyboard .... we must highlight the Bluetooth: to Off. Then again: Bluetooth is on, the keyboard is set, go to bluetooth when you click the keyboard BN1000 it connects. Then I was in my SMS and I could type an entire message with the keyboard, no worries. Well it is still very small, and does not really bring something versus the virtual keyboard Save to reuse our habit of typing keys that sink ... of a star or less.
