Tech Creator Reveals Simple Android Trick to Block Ads and Trackers
Tech creator Trevor Nace has gone viral with a simple Android tutorial showing how to block mobile ads and trackers using a built-in Private DNS setting.
A viral tutorial video by tech creator Trevor Nace has drawn hundreds of thousands of views by demonstrating a simple, built-in method to block pop-up ads, intrusive banners, and online trackers on Android smartphones without downloading third-party applications.
The core of the trick relies on modifying the Private DNS settings on the mobile device. Nace explained that a DNS server acts as the internet's phone book, translating readable web addresses into IP addresses. By default, devices use internet service provider or Google DNS servers, which do not filter advertisements.
Step-by-Step Guide to Ad Blocking
Setting up a secure private DNS allows the device to recognize ad-serving and tracking servers and block their loading before they ever reach the screen. Beyond eliminating advertisements, this modification accelerates page loading times, reduces battery consumption, saves mobile data, and enhances privacy across all device connections and apps.
Users can configure this feature with the following steps:
-
Open the smartphone Settings menu.
-
Navigate to the Network & internet category (labeled Connections on Samsung devices).
-
Scroll down, open More connection settings, and select Private DNS.
-
Choose the Private DNS provider hostname option.
-
Enter dns.adguard-dns.com for ad and tracker blocking, or one.one.one.one for Cloudflare's high-speed encryption server, and tap Save.
Important Considerations
Experts note that while the method is effective, altering DNS settings carries certain implications. Connecting to public Wi-Fi networks in locations like hotels or airports may be disrupted due to the blocking of portal login pages, requiring a temporary revert to automatic settings. Furthermore, system-wide ad blocking can leave blank spaces in content and occasionally disrupt apps that rely on advertising components. Finally, this routes traffic through third-party servers such as AdGuard rather than the standard internet service provider.
