Samsung sends out updates every month as a matter of routine. These updates are security maintenance releases that fix bugs found in Android and Samsung's own software.
The April 2024 security update has already been released for many devices, but Samsung also rolled out another update across the European region earlier this week.
This is a critical update that was released for a wide variety of devices, including but not limited to the Galaxy S24, S23, S22, Galaxy Z Fold 5, Z Flip 5, and the Galaxy A54.
It's likely that this update would be rolling out to more devices soon. Under no circumstance should you skip this latest Samsung update when it arrives on your device.
Update is important for continued access to emergency numbers
Samsung is rolling out this important network update which makes some changes to cellular carrier support. Support for additional bands has been added in some markets to cater to network providers' requirements.
Samsung has also dropped support for select bands, as some carriers may stop using those bands altogether. For example, many carriers are looking to drop 2G networks, meaning that your device won't fall back to the legacy network.
The reason why this is a critical update is because you won't be able to call emergency numbers in those markets if you don't install the update. It will ensure your device has connectivity on all of the network bands that carriers in the region are using, so that in the event of an emergency, you're able to call the required emergency services.
Installing this update will also remove TDD 4G network support for devices bought in Germany, meaning those devices won't connect to these networks in Germany, Belgium, Denmark, France, the Netherlands, Luxembourg, Austria, Poland, Czech Republic, and Switzerland.
Given that the vast majority of carriers in Europe use FDD 4G networks, the removal of TDD 4G network support for users who bought their phones in Germany won't have much impact when they connect to the 4G networks elsewhere.
As it stands, this appears to be a Europe-specific update so it may not be released in other markets. Those who do get the update in Europe should waste no time in hitting that install button right away.
