Android 12 now comes with a 2G killswitch that you might want to make use of


Mobile phone technology has come a very long way from back in the day. Back then before 3G, there was 2G, but fast forward to today and most kids probably did not even know that 2G used to exist.

That being said, a recent tweet by XDA’s Mishaal Rahman has revealed that in the latest update to Android 12, Google has actually included a 2G killswitch feature that basically stops the phone from trying to connect to 2G networks. This is due to security purposes in which hackers can actually use 2G for nefarious activities like intercepting calls and text messages sent over the network.

This is because back in the day, security of mobile networks was not what it is today and 2G was full of vulnerabilities that could be exploited. For example, due to a lack of authentication from towers to phones, hackers could actually make it so that they could impersonate a 2G tower to intercept communications.

Even though in countries like the US where carriers have essentially shut down all their 2G networks, a lot of phone modems can still connect to 2G and will attempt to do so when a 4G signal is weak, so activating this killswitch can help protect your phone and your privacy.

It should be noted that not all phones will support this feature. This is because in order to deactivate 2G, phones will need an update to the Radio HAL version 1.6, which some devices are skipping out on, so depending on your device, you may or may not be able to take advantage of this new security feature.
