If everything fall to plans, Sony's previously released Xperia Z Ultra should be one of the first handsets from the company to receive the Android Lollipop update. However, there's a slight problem. We don't know when that will happen, although some of its handsets are already receiving it.
But that hasn't stopped the community from pushing out the new update unofficially. With Sony already releasing the AOSP source code and binaries for some of its Xperia smartphones, the community has pushed out an unofficial version of Android 5.0 Lollipop.
The new ROM is the work of XDA Recognized Contributor Saatvik Shukla. It can be used as a daily driver if you can cope with some of the few issues involved with the new rollout. As of now, Sony is concentrating on pushing out the update for Xperia Z1, Z2 and Z3.
"The latter should be the first Sony Xperia smartphone to receive the Android 5.0 Lollipop upgrade, but it looks like Google is a little behind with the update's rollout for GPE devices," it also states.
While it's a good thing that an unofficial ROM for the same is already available, but if you indeed look to flash your phone with the same, you should de it at your own risk. There are things here that are not working or have issues working correctly as of now.
