I’ve been pretty happy with the Samsung one tbh. It’s been good at catching spam.

You could try the FOSS option on Fdroid: Yet Another Call Blocker

My Pixel 7 has a call screening function. It asks the caller to identify themselves and why they are calling and shows the dialogue on the screen. Very cool.

Simple Dialer from Simple Mobile Tools. I use a lot of that line for basic stuff. Works perfectly fine really.

If you get a lot of spam calls, maybe think how they all got your number. My experience is that if you’re careful with distributing it, you rarely get them to start with. Regular blocking functionality and spam recognistion is more than enough.

I just block all callers except contacts. I mean in this era, communications for me is whitelist only except when I’m expecting a call from a number no in my contacts, then I turn off my call blockers and use the default spam blockers built into samsung (don’t really know how or if it works, but I rarely need to receive a call outside my contacts). So what I do is just pick up a call, say nothing, just listen. If what I hear doesn’t match my expected phone call, I just hang up. Any extra third party anti-spam apps might just falsely mark a phone call as spam, also, letting such apps monitor your phone calls has a privacy issue.

TLDR: Use whitelist only, unless expecting a call, then disable whitelist only mode. Don’t need 3rd party apps for rare occurences.

I use Silence, but I’ve also heard good things about Yet Another Call Blocker. Both Android apps that are not dialers, but call filters to stop spam.

I honestly just switched to denying all calls automatically from anyone not in my contacts a long time ago. If anyone who isn’t in my contacts needs to reach me, they’ll follow up with an email or text.
