I had a lot of problems in connecting the keyboard to my Android tablet 4.1 but this is not the keyboard that is in question but ... Android after activating bluetooth I did not see that there was in a corner a "search" button, and when I saw it and I clicked the name of the keyboard appeared and the pin code to pair. Then the qwerty keyboard was operating, again this is not obvious to the switch in qwerty, after several tries we must choose the physical keyboard and choose French and then the keyboard switches to QWERTY (no need to buy an app) Alt Gr allows good access to the lower right character keys such as the euro and the @ Android with the left click "supported" replaces the right-click context menus in particular to stop the tasks the battery of the keyboard is very fast, the documentation is in English and really minimalist. There are none in more detail on the site Rii, this site also has a contact address which is rejected.
