How to Block Ads On Your Android Phone Using Private DNS

How to Block Ads On Your Android Phone Using Private DNS

We’re going to step away from Windows tips and tutorials today to show you how to block ads on your Android smartphone. Since many of you have Android Smartphones, we hope you find this tip helpful.

“I am just a poor boy though my story’s seldom told… “ I have an Android Phone and I’ve been using Android smartphones for several years now, so I’m very familiar with them. And yes, I’m quite sure that iPhones have a similar setting, but since I don’t have (can’t afford) an iPhone or any Apple stuff, I can only provide this tip for Android users.

I’ve tested this ad-blocking method using Ablock’s free standard filter (dns.adguard.com). I was surprised how well it works. I was getting so frustrated with full-screen ads that wouldn’t close or ads that used a countdown timer before you could close them. I finally had enough, and my frustration led me to this solution.

So now, I’m going to show you how to use Android’s built-in Private DNS feature to block ads and trackers across most apps and web browsers on your phone. This method uses a free, reputable DNS service (like AdGuard DNS) that handles the filtering for you.

Best of all, this is an operating system setting and does not require installing any special app.

What is Private DNS?

Private DNS is a feature in modern Android versions (Android 9 Pie and newer) that routes all your network requests through a specific, secure server (a DNS server). By using a server that is pre-configured to block ad and tracking addresses, your phone prevents those ads from ever loading.

Here’s how to set up Ad-blocking via Android’s Private DNS feature

Step 1: Open Settings

Tap on the Settings app icon on your home screen or in your app drawer (it often looks like a gear).

Step 2: Navigate to Network/Connection Settings

Look for one of the following menu options, as the name varies slightly between phone manufacturers (Samsung, Google Pixel, etc.):

Connections (Samsung)

Network & internet (Google Pixel/Stock Android)

Wi-Fi & Network

Tap on the appropriate setting to proceed.

Step 3: Find the Private DNS Option

In the Network/Connection menu, look for a section called More connection settings, Advanced, or simply Private DNS.

Tap on Private DNS.

Step 4: Enter the Ad-Blocking Hostname

The Private DNS menu usually has three options: Off, Automatic, and Private DNS provider hostname.

Select the option: Private DNS provider hostname.

In the text box that appears, you will enter the address for the ad-blocking DNS server. For most users, we recommend using AdGuard’s standard filter.

Type the following address exactly:

dns.adguard.com

Tap Save (or the checkmark/OK button).

Troubleshooting & Verification

Wait a few moments: It may take a few seconds for the new setting to apply across your phone’s network connections.

Test it out: Open your web browser (like Chrome or Firefox) and visit a popular news website. You should notice that spaces where ads previously loaded are now empty.

What if it doesn’t work? If you have trouble connecting or if ads still appear, try using a slightly more restrictive ad-blocking address (which may block more content, but is sometimes more robust):

dns-family.adguard.com (This blocks ads and adult content).

Warning: If you have any other VPN or firewall apps running, they may conflict with this setting. You may need to disable the other app’s VPN function for Private DNS to work correctly.

To Turn Ad Blocking Off

If you ever want to disable this feature:

Go back to Settings > (Network/Connections) > Private DNS.

Change the setting from “Private DNS provider hostname” back to “Automatic” or “Off”.

Tap Save.
