Android 5.0 L is expected to become available among several Sony Xperia devices including Xperia Z Series, mid-range smartphones and even low-cost models. Here are the details based on the release dates, end of life cycle and Android KitKat upgrade plans.

Sony Xperia Z Series

Sony Xperia Z2, Xperia Z2 Tablet, Xperia Z1, Xperia Z1S, Xperia Z Ultra and Xperia Z1 Compact are all eligible for Android L according to the official release date which covers the 18-month software support window period. Moreover, successor models from Sony Mobile are also accounted to receive Android L that allegedly known as Xperia Z3, Xperia Z3 Tablet and Xperia Z3 Compact.

For older Xperia Z models released back in 2013, Sony Mobile will provide the discretion about eligibility due to some factors noted on the support Web pages:

- Older Xperia Z and Xperia ZL were released in early 2013 and almost near the end of the 18 months software support. Xperia ZR was released in June 2013 while Xperia Z Tablet in May 2013.

- Within the 18 months support provided by Sony, these devices have already received three major software upgrades from Android 4.1 Jelly Bean. Android 4.2 and 4.3 were rolled out in 2013 while Android 4.4.2 in 2014. Android 4.4.4 KitKat update has already leaked from Sony Mobile forums and PTCRB.

- Sony Mobile holds the right to extend software updates based on system requirements and user demography.

Mid-Range and Low-Cost Devices

Some mid-range and low-cost devices released in 2014 have already received Android 4.4.2 KitKat update including Xperia T2 Ultra, Xperia M2 and Xperia E1 along with any available dual-SIM variants. Similar factors such as software support duration, system requirements and user demography applied on Xperia Z series are likely to be considered on upgrading mid-ranges and low-cost models to Android L.

Android 4.4 KitKat Upgrade Plans

Flow of the Android L update depends on when Google will officially launch the firmware and Sony Mobile needs time to integrate exclusive apps and services before any rollout to users could take place.
