You can block most ads on android with private DNS

This setup filters ad-serving domains at the network level, stopping "generic" apps from loading banners and pop-up overlays. Quick Setup Settings > Network & Internet (or Connections). Tap Private DNS. Select Private DNS provider hostname. Enter one of the hostnames below and Save. Recommended Hostnames dns.adguard.com dns.nextdns.io adblock.dns.mullvad.net p2.freedns.controld.com Important Notes What it hits: Banners and pop-ups in free utility apps and mobile games. What it misses: Ads in YouTube, Instagram, or Facebook (these serve ads through their own domains). If a hotel or airport Wi-Fi won't connect, switch Private DNS back to Automatic or Off until you are past the login page submitted by /u/lil_Reception8859 [link] [comments]
