Hi all my name is Justin. I just got a Zero Devices z4c and a Rii mini i24 Air Mouse. I upgraded to the latest firmware but still have issues like I cant turn on the stick without unplugging and plugging in the device. But the remote can turn it off. Also the resolution on the stick acts up when you lower the bottom screen bar from showing the android buttons so ill lose the top part of the screen. Just little things doesnt seem perfect.
