I could not make this work. My iPhone refuses to see my Xoom, my Xoom can see my iPhone but the iPhone tells me "Xoom" is not a supported device. So I would think its on the iPhone side, but the above poster can get his N7 to work with his 5. So I don't know. I could never make it work. The Xoom is running pure Android from Google like the N7....and my iPhone is on 6.0.1....I use Bluetooth with both on other devices on the Xoom I use a keyboard, mouse, Nintendo wii controller and with the iPhone I connect to my car....(shrug)
Only thing I wanted to do is transfer photos and with an OTG cable I just plug my iPhone into the tablet and transfer all my photos over...
