Android 12 adds function to disable 2G network
The Android 12 operating system incorporated the possibility of activating or deactivating this mobile data network
Android 12, Google’s mobile operating system in its most recent version, incorporated a new optional function in its settings that allows users to disable connections through 2G data networks.
In the settings menu, users have a new section within the ‘Network and Internet’ and ‘SIM’ section, entitled ‘allow 2G’, with a button that allows you to enable or disable connectivity with these telephone networks launched in 1991.
Android informs that even if 2G connectivity is deactivated, this coverage will always be available for emergency calls.
Agencies say this feature is a “win” because it allows users to better protect themselves against a surveillance technique known as mobile site spoofing, often used by police to pinpoint the location of suspects.
When using 2G networks, an encryption system is used between the tower and the vulnerable device, since an attacker can intercept it in real time. In addition, the towers do not have to be authenticated, which allows their operation to be replicated.
