What app to block spam and spoofed calls?

rafnov · May 18, 2025, 8:17am

Carrion unfortunately discontinued by DivestOS team, maybe there is continuation under another name I can’t find?
SpamBlocker is a to bit complex for me to set up…

How Google phone does handle spam blocking so well?
I’m sick of that app but I need spam and spoofed calls blocker very much.

This is what is being used for database.

The database is of USA & Canada : Do Not Call (DNC) Reported Calls Data | Federal Trade Commission

Someone can use that script to host the daily conversion and then you can change the database URL in the app

It’s beyond my capabilities I’m afraid…
Btw. why Carrion is still on F-droid while it’s not functional anymore?

Licaon_Kter · May 21, 2025, 5:08am

I think it’s about it being not broken but not updated.

SkewedZeppelin · May 21, 2025, 10:21am

The primary feature of Carrion is STIR/SHAKEN enforcement which works without any database or updates.

SpamBlocker integrated the same feature a long while ago.

rafnov · May 21, 2025, 11:46am

Ok, I’m testing SpamBlocker again, this time made sure twice STIR is enabled.
But still, SB is too complex for me to configure.
What methods exactly Google uses for blocking spam and spoof calls?
Some say they have own method of identification and own database.

vdbhb59 · May 21, 2025, 12:20pm

They have their own database + few public ones. I do recall someone saying that those database are in open source, but not too sure.

SkewedZeppelin · May 21, 2025, 2:03pm

@vdbhb59 afaik the database is extremely secret, the google dialer app can’t even query it if your device doesn’t pass safetynet

+they use stir/shaken too and some other public databases such as the business directory thingy

vdbhb59 · May 21, 2025, 2:08pm

Similar to Truecaller.

rafnov · May 22, 2025, 12:24am

Truecaller and all those apps are full of trackers :[

Edit: unfortunately. Spam Blocker didn’t work again, it let through first spam call…

Carrion can’t be functional too.

zakk87 · May 22, 2025, 8:05pm

You definately should try to Yet Another Call Blocker. It works great.

rafnov · May 22, 2025, 8:19pm

Last version: 18.11.2021 … It really works?

zakk87 · May 22, 2025, 8:53pm

Yes, I’m using it for a few years on modern and old devices. Try it.

SkewedZeppelin · May 22, 2025, 10:58pm

@zakk87
the database of YACB hasn’t been updated since April 2021, it has no use today.

rafnov · May 23, 2025, 5:23am

Anyway I will check the app, it deserves it for the clean interface, options explanations and “golden middle” between simplicity and configurability.

zakk87 · May 23, 2025, 6:08am

I didn’t know that but its doing what to do. Blocking calls.

Wredna baba od fotowoltaiki i turbin.
I’m LOL.
For those who don’t know language, that means:
A mean woman from solar and turbine.

marcdw1289 · May 29, 2025, 12:56am

YACB is still what I use and it does the job just fine.
When I start receiving unsolicited calls that have a similar number pattern I blacklist using wildcards.
The app is still useful despite the age of its database. Will eventually look for non-proprietary alternatives though.

rafnov · June 1, 2025, 10:51am

The problem is when application does not recognise spam spoofed number too many times, I have no time to check everything and add to add to block list everything like that.

rafnov · June 3, 2025, 4:53am

Hey, new thing appeared in my Droid-ify from izzyondroid repo

Unfortunately used lists from Spain only and nothing about STIR/SHAKEN usage.
