I don't get why other phones don't do this. Is it complicated? I think it just plays a recorded voice greeting. It's simpler than a answering machine. There is no fancy AI or anything like that.
Telcos already keep this information and Google having it as well doesn't really change much. Both are going to sell it plus give it up to law enforcement when asked.
It doesn't play any kind of greeter. Seems to be an online database of spam numbers, I receive calls marked as Spam with a big red exclamation mark. it's not as simple as blocking any calls that aren't already contacts. I could never use that professionally.
It simply rejected calls that lacked caller ID, which is what I assume the GP meant by unknown callers. It wasn't only Nokia either, every single phone that I have ever owned has been able to do this. Its right there alongside novel features such as "sending a text" or "making a phone call."
If you meant the Pixel feature then there are probably lots of videos and posts covering it.
I have one from Verizon since they are my carrier. For free it does an amazing job blocking spam calls. If I was willing to pay (I’m not) it would tell me what kind of spam call it is.
Not worth the price.
I still don’t answer calls unless they’re in my address book or I’m expecting one. But I get very very few calls anyway thanks to the app.
And they are allowed to leave voicemails, which they never do. Real callers do if I get an unexpected genuine call.
Add in the features iOS has had in the last few releases to be able to see transcriptions of voicemails, now live as they’re being left, and most of the hassle is gone.
The spammers trained everyone to stop answering. I shouldn’t have to do any of this. But it’s better than it was a few years ago.
