Android (not familiar with iPhone at all) has solved the problem of blocking unwanted calls, but has it intertwined with "do not disturb", which also affects notifications. I think we'd all enjoy having the feature separated out so that phone calls can be filtered as desired without assuming a silent/lesser mode needs enabling. On an unrelated note, I've many times wished the phone protocol was upgraded to send metadata of your choosing along with the caller ID. Not even asking for a standard, because it'd probably suck. Just provide the means to send some optional data along with the call (which could ultimately put the nail in the coffin of land lines). The primary use case I had in mind would be to authenticate identity (since caller ID can be spoofed), but I'm sure a bunch of new uses would be utilized.
