This is straightforward with browser addons like uBlock Origin where you can add and choose blocklists, but I did searches for doing so system wide and using a VPN but didn’t find clear answers. I could use a DNS service that provides blocklists but isn’t it best practice to leave DNS to the VPN provider? I looked up blocklists and VPNs but didn’t find relevant results.
On Android, I didn’t find any apps that let you filter blocklists and using your own VPN other than Rethink, but the blocklists feature requires using Rethink’s DNS.
So what’s the best way to filter ads and trackers on both 3rd party apps and on OS’s like Android (specific Samsung phones) while still using a VPN?
Mullvad provides a DNS service that can be used with or without their VPN for free: https://mullvad.net/en/help/dns-over-https-and-dns-over-tls
personally, I stick with NextDNS despite using their VPN.

You could probably have something like a pihole between your web traffic and VPN.
Rethink does not require you to use their own DNS. You can choose from several or just use the system DNS.
In addition, it has on-device blocklist where you import rules from various public lists. Just like a desktop ad blocker.
And, of course, I have a VPN configured by downloading a wire guard config file from Mullvad and importing it into Rethink.
