Samsung’s little-known AI Network Guard lets users block internet access for selected apps, cutting off many adverts while adding controls for privacy, distractions and screen time.
Samsung’s One UI 9 includes a little-advertised control that can make free apps far less irritating. Known as AI Network Guard, the feature stops selected apps from reaching the internet, which in turn prevents many of them from loading adverts in real time. For users who rely on free software but dislike full-screen promotions and constant interruptions, it offers a practical workaround that does not require third-party ad-blocking tools.
The function sits inside Samsung’s Connectivity Labs area, a hidden section of the Wi-Fi settings. Android Authority reported that once enabled, it can be used to cut off internet access for apps that still work offline, such as casual games and certain utility tools. That distinction matters: if an app needs a live connection to function, blocking it may break core features rather than simply removing advertising. Android Central, SamMobile and GSMArena all describe the same basic use case, with the feature presented as a way to restrict connectivity on a per-app basis.
Setting it up requires several steps. Users must open Settings, go to Connections and then Wi-Fi, open Intelligent Wi-Fi from the three-dot menu, and tap the option seven times to enable Connectivity Labs. From there, AI Network Guard can be activated after creating a Guardian PIN. Once configured, the user can choose which apps to restrict. Samsung’s own support material says the same process is intended to give owners more control over app connectivity, while also providing a safeguard through the PIN system.
The feature is not only about adverts. Samsung positions it as a way to limit distractions, particularly for children, but it can also help adults who want to curb habitual social media use or stop apps from sending data in the background. Android Authority noted that there are also advanced controls, including scheduled downtime and broader restrictions for all browsers or games. That makes AI Network Guard more than a narrow ad blocker: it is a modest but useful privacy and attention-management tool, especially for apps that request internet access without clearly needing it.
