I've had a Nexus 7 2012 and in the tiny manual there was an indication on where exactly I should touch my phone on it to get NFC communication - near the "e" in the back. That worked great, as I know the NFC area on my Nexus 4 is somewhat in it's middle, but... In a big device like a tablet that's not a guarantee.
However, I have trouble doing the same in the Nexus 7 II. I touch my phone's back to its back but the connection is bad, it comes and goes before I can actually beam stuff... I've tried touching the phone in several different places but didn't get better results.
Where's exactly the NFC touching point on the Nexus 7 II / Nexus 7 2013?
