Sony announced on Wednesday that Android 5.0 Lollipop is rolling out this week for the Xperia Z Ultra Google Play Edition, while confirming that other devices in the Xperia Z lineup will receive the latest software version in early 2015. Sony pledged in October that it would bring Android Lollipop to its entire lineup of premium Z-series devices.
The full list of Sony Xperia Z devices that will receive Android Lollipop between now and heading into the new year are as follows: Xperia Z, Xperia ZL, Xperia ZR, Xperia Tablet Z, Xperia Z1, Xperia Z1S, Xperia Z Ultra, Xperia Z1 Compact, Xperia Z2, Xperia Z2 Tablet, Xperia Z3, Xperia Z3v, Xperia Z3 Compact and Xperia Z3 Tablet Compact.
Android Lollipop was unveiled at the Google I/O developers conference in June, with factory images and over-the-air software updates for the latest version slowly becoming available last month. In mid-November, several users began reporting that Android Lollipop was beginning to show up on the Nexus 4, 5, 7 and 10 as an over-the-air software update.
Sony has also made available Android Lollipop source code and binaries for the Xperia Z Ultra and Xperia Z2 tablet for building AOSP Lollipop on unlocked devices. Android Lollipop source code and binaries for the Xperia Z3, Xperia Z3 Compact, Xperia Z2, Xperia Z1 and Xperia Z1 Compact were posted last month.
Android Lollipop for the Xperia Z Ultra will appear as an over-the-air update.
