Open source spam blocker that actually works, and it's FOSS! (f-droid.org)

I've been getting over a dozen rando calls a day. Basically have had to put my phone on permanent DnD and then allow my contacts to bypass. No more!

This app is successfully blocking those annoying virtual numbers via STIR attestation.

Unfortunately it doesn't fully block SMS. It blocks the notifications, but they still appear in your SMS app needing to be manually deleted.

That hasn't worked for me. The numbers aren't private or unknown. They're just randomized, basically. And if you call them back you'll get an out of service message. I've tried every setting in my (Google) phone app with no luck.

Best case, I was getting silent notifications telling me i had 6-12 missed calls daily. that's with DnD enabled:

With spamblock working, no notifications, no missed calls, no ringing, no going to voicemail. It rejects them completely (notice top 4 calls are simply blocked.)

I've heard some carriers offer better apps than mine and they support blocking these fake numbers... For the rest of us... Try spamblock! So happy.

Interface is a little strange but not too bad.

    It shouldn't matter if they're private or spam or anything else. The only thing that should matter is if they're on your contacts. If your phone is not blocking them I'd recommend trying a different app.

    I'm looking for employment. Real numbers pass STIR attestation. :)

    I don't know what any of that means. Your potential employers don't have email? Or text? If you don't want to block all unknown numbers then why are you doing it?

    This is very simple. I'll explain one more time. Lol.

    STIR attestation is when my carrier can confirm yours.

    If it fails, the call is considered "unverified" and therefore blocked.

    If my carrier can verify your carrier, my phone will ring. This blocks spoofed calls primarily.

    Real people and companies who are not in my contacts but can pass attestation will ring my phone. That means my insurance can still call me even when they use random numbers. That means genuine businesses can call me. That means I can put up a flyer and say my dog is lost please call me if found. And if a real person finds my dog they can call me and my phone will ring and they can tell me they found my dog. Etc.

    That's the dream!

    Its not simple at all. The vast majority of spam calls I get are from legitimate institutions that I'm sure would pass whatever a STIR is.

    Its great that your insurance providers can call you, what's to stop an insurance provider who is not yours from calling you?

    A legitimate caller for one person can often be a spam caller for 100 other people. That's why there exists no way to possibly differentiate one spam caller from another.

    If my insurance provider calls me from an unknown number, they leave a voicemail and I call them back later, or send them an email.

    Well mine aren't!

    Cool. To each their own.

    Legitimate business will generally respect the do Not call list. I don't have any problem with that. I don't get any fucking calls from actual fucking businesses trying to call me with an actual number I can call back and I don't get out of service errors.

    How much more of my time would you like to waste with your stupidity? Blocked.
