Interested consumers may identify the upgraded software for the Galaxy S9 and the Galaxy S9 Plus through the firmware version numbers G960U1UEU3CSA8 and G965U1UEU3CSA8, respectively. The software package has a file size of 1.76GB, and it also comes with January 2019 Android security patch, which fixes up to 27 different security issues including one classified as critical.
The latest software upgrade brings the One UI to the unlocked units of the Galaxy S9 and S9+ in the US. One UI is the latest version of Samsung's proprietary skin and includes several design changes that make it easier for people to navigate the user interface on larger displays.
Samsung has divided the UI into two parts, with the lower half reserved for elements that the person interacts with within applications. Meanwhile, the upper half of the display shows the primary content and other visual information provided by the application. The version of Samsung's software overlay also reduces the number of interactive elements and content, which may help users focus on the task they have at hand. One UI also features a system-wide dark mode and a revamped quick settings panel.
Aside from One UI, this update will also bring the features introduced by Android 9 Pie. Among the features that this software package could bring to the Galaxy S9 and S9+ are Adaptive Brightness and Adaptive Battery features, both of which use AI to help reduce the battery consumption of the smartphone.
The Adaptive Brightness feature takes advantage of AI to adjust the brightness of your device, depending on the ambient environment. Adaptive Battery functionality helps limit the power consumption of the handset by regulating resources provided to apps that the user does not commonly use.
Owners of the Galaxy S9 and S9+ who purchased their devices through carriers like Verizon and T-Mobile have already received Android 9 Pie recently, with some consumers already getting the update since late January. Before users install the software package, Samsung requests users to back up the data on their handsets, and the company also reminds users to update several pre-installed applications after upgrading the smartphones to Android 9 Pie.
Users may get the software upgrades through an over-the-air update, although it may take several days before all devices may receive the software package, maybe even a bit over a week. Consumers can also manually trigger the software package by going to the device settings and continuing to the system update section, though that won't help if an update is not already available for your particular unit. It is also advisable to check if the handset's batteries have enough charge for the smartphone to last the entire update process.
Once users receive a notification saying that the update is now ready for their smartphones, they should upgrade their handsets to the latest version of the operating system. Aside from getting the latest features, this update will also help improve the security of your device.
