It seems Sony's Xperia Z is in the midsts of its first official firmware update. Xperia Z owners in Europe are reporting receiving the update to version 10.1.A.1.434 through the Sony PC companion app, however it seems the update isn't rolling out for everyone just yet, and it's not yet available directly on the device as an over-the-air update either. For our part, we haven't received any update on the unlocked UK model we've been using.
There's also no firm information on exactly what's new in this update, though there's speculation it might address the recently discovered "sleep of death" issue causing Sony Xperia Zs to randomly die. According to XDA forum reports, the latest firmware doesn't fix the slow camera start-up times we pointed out in our Xperia Z review, which is unfortunate.
If you've got an Xperia Z in Europe, be sure to hit the comments and let us know if you're seeing this latest firmware update.
