Last night I was hanging out with some friends, we both have kids and they were goofing around so I took some video. My friend who has a Galaxy S3 wanted a few of the videos so we tried to do NFC and it failed each time. I'm rooted and running JBsourcery, he's stock ICS. What it would do is when we touched the phones together, it would confirm on my phone to send it, I would tap on the video, then it would bring up an error message on his GS3 and then launch the Play Store. I've used NFC once before with another friend who has the Gnex to transfer a persons contact and it worked fine. I was also Rooted at the time and she was running stock ICS. Any ideas why it would keep failing?
