Can someone please explain what the advantages of this feature is compared to putting the phone on airplane mode or silencing it. I guess the advantage over airplane mode is that you still get notifications missed calls and messages, but you can get those immediately after disabling airplane mode. What about advantages over silent mode? you just dim the screen light? Just picture a scenario where the phone in on the desk and you have no access to it or can see it for a night. What are the advantages?
