One of the most effective ways to block mobile ads without touching Chrome settings is using a DNS-based ad blocker like AdGuard DNS or NextDNS. These work across all apps by blocking ad servers at the network level. Just go into your Wi-Fi settings and change your private DNS to a provider like dns.adguard.com.
It works system-wide, so even Chrome gets ad blocking, and you don’t need to worry about browser compatibility or Chrome-specific quirks. If you’re also testing how pages behave under various content-blocking rules, AI-native cloud testing platforms like LambdaTest can help simulate clean and ad-heavy environments for testing on different devices and OS versions.
