Android 12 brings a new feature to users, namely the option to disable 2G connections on their device. This is a new security update for users to prevent their devices from being easily tracked by them.
Because usually many people use 2G connections to track and find out someone’s whereabouts. This is likely because there are times when your device connects to a 2G network in a location where a 4G network is not available, and the Electronic Frontier Foundation notes that this poses a security risk.
Fortunately, Google has now added the ability to patch this vulnerability that is often misused by others by disabling 2G modems on Android phones via the Android 12 update. The 2G modem switch, according to EFF, is a useful feature that should protect devices from “technological surveillance.” invasive police” is known as mobile site simulator.
For the uninitiated, this simulator is used to mimic an actual 2G tower to intercept communications, due to the lack of authentication from tower to device. There’s also a lack of strong encryption between the 2G tower and the device, which could allow attackers to crack that connection in real-time to intercept calls and text messages.
Disable 2G Connections on Android
While Google has given Android users the option of not allowing 2G cellular connections on their devices, the setting is still enabled by default.
If you want to turn it off, you can go to Settings =>Network & Internet => SIM. Now you have to select Allow 2G. After that, select the Off Setting. This method also depends on your device and the version of Android you are using, the steps may vary slightly.
According to reports, 2G is the second generation of cellular communication created in 1991. Many vulnerabilities were found in it, and it uses weak encryption between towers and devices which can be easily broken in real-time by attackers to attack calls and text messages.
