To set up systemwide custom ad-filtering DNS (such as Mullvad’s secure DNS over TLS, including ad blocking and enhanced privacy) on Android, follow these straightforward steps. This ensures safer browsing and blocks unwanted ads across all apps and browsers 🚀.

Android Devices: Systemwide Secure DNS 🌐

Android 9 and newer versions support DNS over TLS (DoT) for systemwide encrypted DNS. Here’s how you set it up with Mullvad’s ad-filtering DNS, for example, extended.dns.mullvad.net.

Step-by-Step Instructions 📱

1. Open Settings ⚙️

   • Launch the Android Settings app from your app drawer or home screen.

2. Access Network & Internet 🌍

   • Scroll down and tap Network & internet.

3. Configure Private DNS 🛡️

   • Tap on Private DNS.
   • Select Private DNS provider hostname when prompted.

4. Enter Custom DNS Hostname ✍️

   • Type in your chosen Mullvad DNS service. For enhanced filtering, enter:
     • extended.dns.mullvad.net
     • Other options include:
     • adblock.dns.mullvad.net for ad filtering
     • family.dns.mullvad.net for family-friendly filtering

5. Save Your Settings 💾

   • Tap Save or OK.

6. Test and Enjoy 🚦

   • Once set, your device will use the Mullvad DNS (ad-filtering and secure) systemwide. All apps, browsers, and services will benefit!
   • To test: Visit Mullvad’s DNS check page (search for “Mullvad DNS check”) to verify your settings.

Useful Tips 📝

• If Android can't connect, the DNS server might be too far, causing high latency. Try a different server if needed.
• Using custom DNS servers may impact privacy, as DNS requests are visible to the provider you set. Mullvad’s servers, however, do not log requests and prioritize privacy.
• You can always revert by selecting “Automatic” in Private DNS settings if you notice connectivity issues.

✨ With these steps, your Android device is now protected by a systemwide, secure DNS—blocking ads and keeping your browsing private! Protect your phone, enjoy ad-free apps, and browse with peace of mind! 🌈🛡️
