Japanese consumer electronics major Sony has reportedly began rolling out Android Jelly Bean v4.2 to three Xperia series smartphones across the globe.

The report comes just a few days after Sony confirmed to release the new firmware to four of its devices - Xperia Z, ZL, ZR, and Tablet Z. The updates will be released in phases, as these models are region specific.

Sony community website, Xperia Blog, has reported that the Xperia Z (C6602) owners in China have begun receiving the update (build number: v10.3.1.A.2.67). Xperia ZL(C6503 LTE) users in Germany, Middle-East, Singapore and US (C6506-LTE variant) regions have also started to receive the Android OS update having the same build version.

In India, Sony has released the new update only for Xperia ZR (C5502) model. Other models are expected to follow soon. So far, out of four Xperia devices, there no reports of new updates being rolled out to Tablet Z in any of the regions.

All the four devices - Xperia Z, ZR, ZL and Tablet Z were launched early this year. They shipped with Android v4.1 Jelly Bean OS out-of-the-box, and now with the new firmware update they are all set to get a boost in their performance, besides a bug-fix for battery, camera and display.

Recently, Sony also rolled out Android v4.1.2 software update to another 2013 model - Xperia SP (both LTE and HSPA+ variants). It brought new UI visuals as well as improved the camera, regarding its low-light image capture mode. It also made the navigation and status bar semi-transparent.
