Use Rethink DNS, I'm super picky about everything my phone does and I'm dumbfounded that a GitHub open source project provides the absolute most control over my phone 11 stars, say good bye to adds and all crap. Option to lock down and not allow anything to bypass your custom DNS over https setting, which kills chrome because chrome hardcodes using 8.8.8.8 and 8.8.4.4, provides actual URL firewall with wildcard urls, DNS black holes, ip block ranges. It's a good dream come true for URL and IP control. Download from GitHub and now in play store. I can't prop out this project enough and it's open source and free.
