Block Most Ads on Android — No Root

A short, safe, reversible method using Android's Private DNS (DNS-over-TLS). Minimal battery impact, system-wide filtering for most apps and browsers.

Quick Steps

1. Open Settings → Network & Internet (or Connections).
2. Tap Private DNS (often under Advanced).
3. Select Private DNS provider hostname.
4. Enter exactly: dns.adguard.com
5. Tap Save. Wait for status to show active/connected.

Why it works

Private DNS prevents your device from resolving known ad/tracker domains. If the DNS never resolves an ad domain, the ad request fails before content loads — lightweight and system-wide for most apps.

Troubleshooting

• One typo in the hostname breaks DNS — double-check.
• Toggle Wi-Fi or Airplane mode to refresh the network stack.
• If a site behaves oddly, temporarily set Private DNS to Off or Automatic and test.

Alternatives

If your device lacks Private DNS (Android <9) try a local VPN-based blocker (e.g., Blokada or AdGuard non-root). They catch more cases but may use slightly more battery.

Rollback

Settings → Network & Internet → Private DNS → choose Off or Automatic to revert.
