The entertainment apps stalled on out phone are various. Watching videos, playing games and livestreaming, we can find a lot of things to entertain ourselves on our phones. The apps are updated frequently, many of them are usualy unexpected. We rather lie on the couches and stay with our phone.than spend a lot of time e hanging out with friends. Some people have been concered about this phenomenon, they have a great pharse to describe it: spiritual opium. But nothing changed.
