Android Authority Writer Uses NextDNS to Block Deceptive Ads

Mobile ads on Android devices are becoming a significant issue, marked by a spate of surprisingly manipulative pop-ups masquerading as genuine notices or system update alerts. While tech-savvy users have learned to sniff out the rubbish, others have not developed this skill, according to Android Authority reporting by Andy Walker. Walker previously documented how his dad encountered a deceptive PDF ad on his phone, prompting him to tap a fake Update button and install numerous bogus PDF apps from the Play Store. That particular ad lurked inside a preinstalled office app, but the problem has since expanded into Google’s own ecosystem.

Deceptive PDF Update Ads Target Users Inside YouTube

The issue escalated when Walker’s dad forwarded a screenshot of a deceptive ad utilizing the old PDF app is out of date trick, this time appearing directly inside YouTube. To verify whether it was an isolated incident, Walker opened YouTube on his own Pixel phone and lost it when a near-identical ad appeared at the top of the screen, as noted in Android Authority’s coverage. This discovery prompted an online poll by the publication asking users if they or someone they know had ever fallen for a deceptive ad on Android. Out of 94 total votes, 18% answered yes for themselves, 38% said yes for someone they know, 13% came close, 5% never encountered them, and 26% blocked all ads.

Why NextDNS Was Chosen for Network-Wide Content Filtering

Because his parents use their mobile devices for communication, financial transactions, and storing memories, he needed a safe and secure platform free of predatory ads. However, because he does not live with them, any chosen solution required specific capabilities. He needed remote access and monitoring to update settings or disable the tool if necessary, ruling out standalone ad-blocking apps like Blokada. Furthermore, he needed network-wide filtering to screen an older Android streaming box used to watch TV content, a free trial period to evaluate efficacy, separate profiles for his mom and dad, and a simple set-and-forget setup requiring just a single switch on their phones.

Deploying NextDNS to Block Malicious Traffic Across Devices

To solve the problem, Walker settled on NextDNS, an old favorite content filtering solution he previously covered and used on his own devices. Described as a fine-mesh digital net that allows preferred traffic through while catching undesirable content listed by user-selected blocklists, NextDNS offers high customizability and scalability. The service works with any device equipped with a user-customizable DNS field and utilizes Android’s Private DNS slot to ensure that all traffic—across both Wi-Fi and mobile data—remains filtered.
