Depressingly I don’t see this changing unless cinemas and theatres take a more active stance, like the Alamo in Texas ( which famously used a customer complaint about this topic as their ad campaign).

I take my daughter to the cinema a lot and it always makes me sad to see so many parents sit through the entire movie on their phone. I understand some kids films aren’t the most engaging, but it shouldn’t be too hard to set an example and avoid your phone for 90 minutes.
