Everyone else will be in peace if they do what they ostensibly came for, which is to look at the screen. Many movie attenders feel they need to be critics of their neighbor’s mode of dressing, etc. And fuming about a neighbor doing anything with something electronic is a particular vent for their sense of self superiority.
If you are distracting people by “doing something electronic” obviously you aren’t there to watch the movie. Those people need to have some manners/etiquette taught to them think of others besides themselves.
Any one who thinks it is proper and good to cause a disruption to others has the inferior morals and ethics. Everyone else is superior to them in this fact based on actions and nothing else.
If you need to talk with others on your phone either by voice or text just take it outside the theater. People will appreciate you thinking about them.
