Samsung Galaxy S9 (SM-G960F), codenamed starlte, is a mobile phone released in 2017. It has 4GB of RAM, 64GB of UFS storage, Exynos9810 SoC and 1440x2960 Super AMOLED display. This initial device tree enables the framebuffer pre-initialised by bootloader and physical buttons of the device, with more support to come in the future.
