While most people are busy talking a bout the new Samsung Galaxy Alpha, owners of the launch-edition Galaxy S5 may notice a new firmware being rolled out. Samsung quietly began updating international Galaxy S5 devices (not the U.S. versions) to firmware build G900FXXU1ANG9 earlier this week. The update is still in the early stages, with only a few select European markets receiving it via over-the-air (OTA) transmission. Now for the million dollar question: what exactly does this nw firmware update do? We still don’t know the full details, but early reports suggest it’s a minor update which brings performance improvements, greater stability, and bug fixes to the international version of Samsung’s flagship smartphone. Firmware G900FXXU1ANG9 does not introduce any new features or utilities that we know of. Regardless, it’s the official firmware for the international version of the Samsung Galaxy S5 model SM-G900F, so you should definitely use it on your device.
