Here in Japan, most concerts have a strict no-photos policy. In smaller venues, I've seen this enforced by guards shining bright focused flashlights at you if you try to take a photo/video. Seems to work well. Some artists stop to do a "ok let's all take a photo together now" bit near the end for those who want a memory.
What I really loved about phone use (or better: not use) in Japan is the rules on trains.
While eating some lovely fermented fish dish out of a bento box is completely acceptable using your phone to make calls is definitely not.
My understanding was (and please correct me if I'm wrong) that in the Shinkansen you can move out of the car to make a call, in local public transport it's an absolute no!no! (well, probably the bento box is also not that hot an idea in public transport).
With very, very few exceptions (mostly by foreigners) I've experienced this rule as respected.
I had a hard time adapting back in Europe with all the noise and chatter going on permanently.
