Android 16 includes a Mobile Network Security suite that can detect Stingrays—fake cell towers that intercept calls and texts. The feature alerts users when connecting to unencrypted networks or when their device identifiers are recorded. However, full functionality requires specific modem hardware, currently limited to the Pixel 10 series.

Google has slowly added these protections since Android 12, which first allowed disabling 2G connectivity. The hardware dependency explains why most Android phones, even new models like the Galaxy S25, only offer the basic 2G toggle. This gap highlights the challenge of rolling out security features across fragmented Android hardware.

For Pixel 10 owners, enabling the settings under Security & privacy > Mobile network security provides real-time alerts. As more devices adopt compatible modems, this could become a standard defense against surveillance. The move reflects growing pressure to secure mobile networks against both law enforcement and malicious actors.
