Samsung's upcoming Galaxy Tab S3 reportedly won't be out until Feburary 26, but the Wi-Fi only version's device firmware has already hit the net, putting things like the system sounds, wallpapers, and device code out there for the community to inspect and use. While there may be some slight differences in the LTE version to account for the added connectivity and features that can tie into it, things are likely to be mostly the same between devices. The firmware file boasts a device code of BTU, and firmware version T820XXU1AQB9. The firmware seems to be based on Android 7.1 (Nougat), and has a build date of February 13, 2017. The Android Security Patch level is the latest February patch, which is starting to make its way to non-Pixel, non-Nexus devices.
The thirteen wallpapers that are included with the firmware files, which can be found below, are all decidedly fractal affairs, made to look aesthetically pleasing and sharp at the same time. The wallpapers boast a resolution of 2,048 by 2,048, making them scrollable on the Galaxy Tab S3's 9.7-inch 2,048 by 1,536 screen. The wallpapers are rather large and sizeable, and the file names give away their functions. One is meant to be the default wallpaper for the device, others are meant to be backgrounds associated Samsung's KNOX device security suite and service, and a few others are regular wallpapers, to be employed as users wish. The high resolutions and sharp lines would go beautifully with almost any device design and home screen, despite being specifically designed for the Galaxy Tab S3 and its Nougat-based TouchWiz interface.
The released firmware files, available through SamMobile, can be flashed with Samsung's proprietary ODIN tool, or the open-source, Linux-friendly Heimdall alternative. This means that adventurous early adopters can experiment with their new Galaxy Tab S3 units, so long as they're the Wi-Fi only model, without fear of not having a fallback in case they break something on the software end.It also means that work on porting the device's firmware to other devices can begin, if any developers are interested. It should go without saying that the driver files contained therein are specifically made for the hardware in the Galaxy Tab S3, and forcing them to flash onto other devices may have some unintended side effects, up to and including inoperability, also known as bricking.
