95% of my incoming calls are now spam. Most of them are some strange pre-recorded Chinese voice with music playing in the background but I occasionally get a free hotel stay as well.
So far Google has rolled out Call Screen. This means I can waste my time watching Google Assistant talk to the spammer. It's way faster not to bother, hang up all calls and delete the voicemails later.
It seems like instead of Call Screen there could be a better way to deal with this.
Firstly, send any call not from someone in my contacts directly to voice mail. This would actually solve a lot of the problem.
Next, for extra credit, run spam detection on the voice mail before sending it to me. If it's two seconds long and blank then just bin it. If it's Chinese with music bin it. Only if it passes the smell test should it appear in my actual voice mail. Google is very good at this for Gmail.
