Here are a few of my smartphone pix. I'm making a number of books on this subject. But smartphone pix are just a few of the hundreds of social doc projects I am doing. So smartphone pix are no big deal to me. If I see someone pointing I shoot it...someone yawning I shoot it...someone kissing I shoot it...someone with a phone I shoot it...lady in a hijab I shoot it...etc and etc. Have lots of projects and you will always have something to shoot on the street.
If any photo violates policy, just remove it...you wont find pix like this on The Atlantic.

I got a lot more of them. I also had one of a guy getting oral sex on the side of a road with cars driving by and a smartphone in the corner. But didn't want to push things. Social doc photography has no limits. If it has a human in it and is legal to shoot...you shoot it. (If it is of decent interest.)
