Google is introducing a new feature in Android 16 that will alert users when their devices connect to potentially dangerous, unencrypted cell towers including fake towers known as “Stingrays.” This feature marks a crucial advancement in the fight against sophisticated surveillance tactics often used by government agencies and malicious actors.
Stingray devices, also known as IMSI catchers, mimic legitimate cell towers to trick nearby smartphones into connecting. Once a connection is established, these devices can intercept calls, read text messages, and even track user locations. Because they exploit a weakness in the cellular network protocol, most users remain unaware when they are being monitored. The new Android 16 feature aims to change that by offering real-time notifications about insecure or suspicious network activity.
The warning system works by detecting when a phone connects to a 2G tower or any unencrypted network lacking proper authentication. These older networks are highly susceptible to spoofing and interception, making them a prime target for Stingray attacks. With this update, Android will immediately alert users with a notification, giving them the opportunity to disconnect or switch to a more secure network.
To enable this feature on Android 16, users can navigate to Settings > Security & Privacy > Cellular Network Security and toggle the warning system on. Additionally, users will have the option to restrict their devices from connecting to 2G networks altogether — a feature that first appeared in Android 12 but gains more prominence now.
The growing awareness of digital privacy and state-sponsored surveillance has pushed tech companies to enhance user protections. Google’s move reflects an industry-wide shift toward transparency and security by design. While this feature won’t stop Stingray devices outright, it empowers users with crucial information and gives them greater control over their privacy.
As mobile threats evolve, features like this one in Android 16 will become essential tools for safeguarding personal data in an increasingly connected world.
