Good keyboard for different uses

This review concerns the Rii RT-MWK02 + version AZERTY (FR).
Benefits:
- This keyboard works perfectly (all keys are recognized and pad serves mouse) on Linux and Windows. (Tested under Arch Linux and Ubuntu and Windows 7 64-bit). Windows check that the "Supported Bluetooth Service" is Started if you are unable to Show Bluetooth Devices.
- On Android, it captures faster than the virtual keyboard, and provides arrows that some models / manufacturers do not provide virtual, allowing more easily correct his typos. It also provides a mouse cursor, which can afford not to tap the screen to return to certain actions.

Disadvantages:
- The backlight can only be activated when the keyboard is paired.
- Everything that relates to the Fn (blue buttons) is not visible when the backlight is activated because it concerns only the white, not blue.
- Too bad it is not a true qwerty keyboard (eg the keys "*", "=" are not placed in the usual place "!").
- The space has only one touch key, which makes it a little hard to activate if not supported well in the center.
- The charging plug is not the new USB micro-B standard but USB mini-B (so you will probably need two chargers if you go on the road for long: one for the phone and one for the keyboard)
- On Samsung Galaxy Note (Android), I have not managed to run all buttons
... The lower / upper keys AltGr and Caps have no effect
... Fn-M gives ... Fn-ù gives> instead of μ
... With ConnectBot application, the Ctrl key has no effect
... But attention because the "Fn" + "CTRL + ALT + DEL" works fine on Android!
- I tried unsuccessfully to make it work with Android 2.2 but the problem may be of Android (the pairing is done but then nothing)

Do you have the same problems with Android? I am running Android 2.3.6.
