HTC is today pushing out a rather large unexpected over-the-air update to all its unlocked One Mini handsets currently located in Hungary. According to the changelog, the upgrade brings Android 4.3 Jelly Bean and the latest version of Sense 5.5 to the device, together with a multitude of additional bug fixes, speed optimizations and stability improvements, as well as a bunch of new soundtracks for the built-in Video Highlights feature.
