Display alert when calling during night/down time hours
I don't know about you but this small thing to avoid the "oops sorry I woke you i didn't realize what time it was" call is not something I am aware of other mobile operating systems doing, and it's a more empathetic design tidbit like to see Calls have. Displaying a small alert during sleeping hours/night time accounts for the fact that people sleep and reduces the potential disruptiveness of phones (that are not just your own) overall.
This could apply when when you're placing local calls within your timezone, e.g if you're awake at 4am, or if you're placing calls internationally where the remote time is during of "night time hours", e.g. a call from New York to Hong Kong.
In theory, it could just be a simple popup when you hit dial something like the following (phrasing subject to change):
This prompt makes you acknowledge that you're about to call someone who may be asleep.
Problems associated with this would be:
- determining the conditions for "night time hours" e.g. 1am to 5am
- determining what time it is in timezones that are not local from local data
This requires knowledge of your contacts timezones, and wouldn't apply if Calls had no information on your contacts' timezones and calls would be placed normally. This is an edge case, but it would still be nice to cover that in design.
