That already exists for Android but it only fixes those not doing CID spoofing. I get a lot of calls marked as spam but it won't and hasn't fixed the problem of spoofed caller ID numbers though which are those calls that match the first 6 digits of your phone number. Those they just constantly rotate and change to match the number they're calling at the moment. I've had a few people call me and even my work desk number after some cid spoofer has used those numbers.
