The 2G connection network and the danger of spying
Launched in 1990, the 2G network is one of the oldest forms of connection. However, this type of technology is outdated and has several security weaknesses in view of the great advances in this area in recent years.
Thus, one of these vulnerabilities is that it lacks authentication between the mobile device and the tower. The other deficiency concerns a very weak type of encryption for communication.
Due to these weaknesses, the 2G network can easily be targeted by so-called Stingrays. These are tools similar to telephone networks and which are a potential device for espionage.
The Stingray is capable of connecting to cell phones and accessing user data. In this way, the possibility of deactivating the 2G network on Android 12 cell phones is being celebrated, putting an end to this type of attack.
How to disable 2G connection network on Android 12?
To deactivate the 2G network on your Android 12 cell phone is very simple. Go to your device settings and then tap on “network and internet”.
Then look for the “SIMs” option and check the permission for 2G. However, depending on the model of your device, the route may be slightly different.
It is important to note that, in order to be able to perform this function, the smartphone must have version 1.6 of Radio HAL. And if you're wondering if disabling your cell phone's 2G could cause any problems, know that the answer is no! This is because the 2G network is only used when we are in places very far from urban centers, that is, in places that are not covered by 3G and 4G networks.
So, now that you know how to turn off the 2G network on Android 12 phones to avoid spying, take the opportunity to forward this article to your friend who would also like to know.
