The unlocked European Samsung Galaxy S5 (SM-G900F) is today receiving an over-the-air update with "improved performance." It's the second major update for the European version of Samsung's 2014 flagship, the first having arrvied a month after the device first went on sale. The upgrade comes in two parts — first, a 194MB update, then immediately after, another 1MB update, both updates touting the aforementioned performance tweaks. After all that, you're bumped up to firmware version XXU1ANG2, which is still based on Android 4.4.2 KitKat.
The hefty size of the update suggests there's more to it than mere performance tweaks, though we've not been able to track down any other differences thus far. Nevertheless, our handset seems just a little quicker following today's updates, which is a welcome improvement.
We've received the XXU1ANG2 update on our UK model GS5 today; as usual, other countries and carrier variants may take an extra few days or weeks to see the OTA.
