Sony is now seeding the latest Android 5.1.1 Lollipop update for some of its older Xperia Z devices. In July, the Japanese tech giant had already released the Android 5.1.1 update for its newer devices, such as the Xperia Z2 models and the Xperia Z3 models.

The update will install the build number 10.7.A.0.222 on all the aforementioned devices. The Xperia Z2, the Z3 , the Z models have been blessed with Android 5.1.1 Lollipop; however, the update is still unavailable for users of the Xperia Z1 and the Xperia Z1 Compact, Android Headlines reported.

These smartphones are likely to receive the Android 6.0 Marshmallow first. However, there is no confirmation on whether Sony will be releasing Android 6.0 for Xperia Z models from 2013.
