Do you feel there is a lot of rude or inappropriate cell phone use today among younger generations particularly?

So I’ve noticed in general but in particular people around my age (20) and under seem to use their cell phone at inappropriate times and in rude ways.

For example:

I seen various times when I’ve been watching movies with people that they go on their phone and watch videos with the sound on while everyone else is trying to watch the movie

I see a lot of people publicly play music or video audio from their phone. I get it can happen on accident but I think it’s rude when people intentionally do it out loud. I think it’s different if they had ear phones in.

I’m sure there’s a lot of other examples I could give. What are your guys thoughts and opinions on cell phone use? What direction do you see the future going?
