Sony has commenced the roll-out of the Android Lollipop software upgrade for three more Xperia line-ups, the Xperia Z2, Z2 Tablet and Z3 Tablet Compact, after the software update was earlier released to Xperia Z3 and Z3 Compact smartphones.

The Xperia Z2, Z2 Tablet and Z3 Tablet Compact will get the Lollipop goodies just like the Z3 smartphones. These include a new look based on Google's material design, new notifications and lock screen, multi user profile and guest mode. The upgrade also offers Xperia users better storage control and customisation with the option to move applications from internal storage to SD card.

Since the update has just started, it will not be available for all users at the moment. The timing and availability might vary depending on the market and carrier.
