Android 12 Now Can Turn Off 2G Network, For Device Security
Android 12 was officially launched in October 2021 and several OEMs have pushed the availability of this new mobile operating system to a number of their eligible smartphone and tablet devices.
While features like Material You and widget enhancements have caught the attention of many, other recent additions seem to have gone unnoticed by the public. This feature is Android 12’s ability to turn off 2G networks on smartphones and was only revealed a few days ago.
A tweet from Mishaal Rahman’s Twitter account said that a change was found in Android 12 in the form of an option to turn off 2G networks on smartphones. Google apparently quietly rolled out the feature late last year, which allows users to increase the security of their devices at the touch of a button. This feature also received a warm welcome.
In some countries, many telecommunications providers have turned off the availability of 2G networks (following the next 3G), but most smartphones still have 2G modems and continue to try to connect to the nearest 2G signal, and this is the source of the problem.
Launched back in 1991, this outdated service has many vulnerabilities, and its security is outdated. For example, the encryption capability between the 2G tower and the device is very weak, and this results in a network that can be easily breached, to intercept text messages and calls. Another problem is the lack of authentication from tower to device, which allows for fake 2G towers, simulating cellular sites, which can also be a source of eavesdropping.
Even though the average smartphone currently uses a 4G network that is safer, under certain conditions, the smartphone network can change to 2G, especially when the 4G network is very weak, so smartphones also have the vulnerabilities brought by the 2G network.
So, if you want to protect your smartphone and data, the best way is to turn off the 2G network, which is available in the latest version of Android 12, as suggested by Google.
However, not all devices with the latest Android 12 version can use this feature. At a minimum, the device requires an update on Radio HAL to version 1.6 or later, which many Android devices (especially those released still with Android 11 or earlier) don’t provide it, due to requirements issues with Google Requirement Freeze (GRF). If your device is one of them, then you cannot turn off the 2G network with this new feature.
However, the latest smartphone devices that ship with Android 12, including the latest Pixel and Samsung smartphones, will be able to take advantage of this feature. To turn off the 2G network, go to the Settings → Network and Internet → SIMs → Allow 2G page and slide the available switch.
What is Android System Intelligence?
For those of you Android phone users, you may often know Android System Intelligence on your Android system.
Android System Intelligence is a core component of an Android-based operating system that is responsible for many of the core features of a smartphone, such as providing automatic response options and keeping the screen on as long as the camera detects that you are looking at it.
And since it’s a component of the Android system that performs many useful functions, there’s no need to worry if you notice it running on your phone. You can disable Android System Intelligence if you want, but doing so will cause many features to stop working normally.
What features are enabled by this Android System Intelligence?
Here are some of the most important features enabled by System Intelligence:
- Sensor Attention: this is a sensor that can keep your phone’s screen active as long as you look at the screen. This prevents the screen from turning off while you are watching videos but leaves the screen off if you are not watching anymore.
- If you have ever experienced an incident where when you leave your Android phone when you watch a video and the screen turns off, that’s where the Android System Intelligence function works.
- Autorotation: This feature automatically rotates the screen orientation based on the position of the Android phone.
- Automatic captions: This feature is capable of generating automatic captions for media that have no captions available.
- Smart text selection: Activates targeted actions when you select the text, such as long-pressing an address to see directions.

- Notification management: Inserts useful action buttons into notifications, enabling notifications to open the relevant application or provide the required information when tapped.

How to Enable Google Play Protect
Google Play Protect is a security feature offered by Google for Android devices. It helps protect your phone from malware, spyware, and other harmful applications by scanning all installed apps regularly. The feature is automatically enabled on your phone, but you may want to enable it manually if you have disabled it or if you have a new phone. In this article, we will guide you step by step on how to enable Google Play Protect on your Android device.
Step 1: Open Google Play Store
The first step is to open the Google Play Store app on your Android phone. You can find the app on your home screen or app drawer.
Step 2: Go to the Play Protect section
Once you have opened the Google Play Store, tap on the three horizontal lines located on the top left corner of the screen. This will open a menu, and you need to scroll down to find “Play Protect.” Tap on it to access the Play Protect settings.
Step 3: Enable Play Protect
Once you have opened the Play Protect section, you will see a toggle switch at the top of the screen. If it is turned off, you need to turn it on. If the toggle switch is already turned on, then the feature is already enabled, and you don’t need to do anything further.
Step 4: Check for updates
If you have just enabled Google Play Protect, it is a good idea to check for any updates. To do this, go back to the Google Play Store, and tap on the three horizontal lines again. Scroll down to “My apps & games,” and tap on it. You will see a list of all the apps installed on your phone, and if any updates are available, they will be listed here. Make sure to update all the apps to ensure that they are protected by Google Play Protect.
Step 5: Scan your device
After you have enabled Google Play Protect, it is important to scan your device to check if there are any harmful apps installed. To do this, go back to the Google Play Protect section and tap on “Scan device.” Google will then scan your phone for any harmful apps, and if any are found, you will be notified. You can then choose to remove the app or keep it installed.
Step 6: Keep your device updated
It is important to keep your Android device updated with the latest security patches and updates. To do this, go to the Settings app on your phone and tap on “Software update.” Check if any updates are available, and if they are, install them. This will help keep your device protected from any new threats that may emerge.
Step 7: Be careful when downloading apps
Google Play Protect is a great feature, but it is not foolproof. It is still important to be careful when downloading apps from the Google Play Store. Make sure to only download apps from reputable sources and check the reviews and ratings before downloading.
