I am using a Nexus 7 2013 edition tablet 6.0 with Mi WiFi 2 repeater. It seems to fly very well. I have also updated the latest firmware.
Rabbit, I am also using a Nexus 7 2013 but running android 6.0.1. It flys great, takes and saves photos, but does not save video. It appears as if it is taking a video with the timer running but no video is saved. Can you confirm that you are able to save video?
