Adblocking for android phone

What would be your recommendation for blocking ads on an android phone? Do you use one and, if so, what’s your 2 cents on what you’re using? Where have you seen the biggest improvement (reduction) if it works well?

For me, the best bang for your buck as far as effort was to just set the DNS Provider to dns.adguard.com. Then use whatever adblocker or vpn solution you want on top of that. Has worked pretty well for me.
