Yup, Swedish police issued a search warrant and raided Mullvads offices last year. They left empty handed as Mullvad does not retain ANY customer data.

I checked; the engines still there. How do I turn the light off?

I mean... Scamming people is illegal too...

With increasing frequency; spam calls spoof their caller ID to be a number/business/organization local to you which isn't linked to them. Either to masquerade as a familiar name as part of the scam or just so blocking or calling back is pointless.

Filtering that is next to impossible unless you just use a whitelist of acceptable callers.

It's a broken system.

OP asked for some new (to them) options, of which there are plenty. Instead some people are re-listing the things op's already said they've tried.

Not even remotely helpful. If you don't have anything new to suggest, just don't suggest anything. Instead have a read through some of the actually helpful comments others have posted.

I know I can install firefox and get the uBlock on it but firefox android is a little bit slow so I prefer to use Opera browser

Very clearly asking for something else, but people repeatedly recommend OP uses firefox... SMH

All the people suggesting firefox...

Pihole for network wide ad blocking (no ads on all apps on all devices within the LAN) then self-host a vpn to keep your phone within that lan.

Tis what I do at least.

Blocks pretty much everything except Youtube, and Twitchs video ads as they serve their own ads from their own domain's as well as things like sponsored posts on reddit/twitter/facebook.

Don't watch much Twitch, Youtube (re)Vanced is a thing, and Twitter/FB/Reddit can all die in a fire. So none of those are issues for me either.
