Lock screen widgets and UI tweaks come five months after other models
Coming up on five months after over versions of the model received an update, the Sony Xperia Z on T-Mobile is getting the bump to Android 4.2.2 starting today. The software version 10.3.1.E.0.191 (coming in at 185MB) is rolling out to users over the air now, and it brings all of the same features as we saw on the Xperia Z, ZL and ZR several months ago.
That means you'll now have lock screen widgets, camera access from the lock screen, an overall facelift of the launcher and a few different styling changes through the settings and multitasking menu. You'll also have a new way to customize quick setting toggles in the notification shade, and a few other tweaks and improvements.
If you have an Xperia Z on T-Mobile you can check for the OTA now, or hook up to your computer and download the update manually via Sony's PC Companion (or Sony Bridge For Mac) software.
