The Sony Xperia Z is receiving its first system update, and fairly quick at that. However, Sony may have every reason to be fast. Without a changelog, or issues fixed, this might be the update that delivers the sudden death fix Sony promised. Which is a very fast response on Sony’s part, if this is actually the fix. However, without official word, we can’t be sure.
To grab this update on your Xperia Z, you’ll need to fire up the Sony software on your computer. The OTA doesn’t seem to be available at the moment. The new software version is 10.1.A.1.434 and is coming to many devices. Tell us if you notice anything new!
