The secret to using a Tab 2 is the cable. A poor or inferior cable will cause a flashing effect & not work. However that can be overcome by turning on the aircraft & rc first, then turn on the tab. If you can get a good USB 3 cable that works even better but I wasn't able to get one that worked for my spark. But when I got the Air I used the DJI cable. Went from the USB A port to the micro on the TAB, And voilà, no problems whatsoever. But since I've heard so much about the iPad I'm going to try that soon. I'm still fumbling around with it first. Never having used Apple before. Wish they used a back button like Android!
