It is better late than never. Through its official Twitter account, Sony announced that the Android 5.1.1 Lollipop update for Xperia T2 Ultra and Xperia Z series devices started rolling out since Tuesday.
Although Google is preparing to launch Android 6.0 Marshmallow and many still continue to expect the Android 5.1 Lollipop update, Sony is still giving users who bought their 2013 devices, something really outstanding and we do not see very often.
The Sony Xperia T2 Ultra is the latest device of this phase of renovation, as was announced in January last year and not two years ago as the Sony Xperia Z (original). The update promises to bring some improvements in device performance and interface changes that more closely resemble what they have with Android Pure as the Nexus 6 and more similar to that provided with the new Sony Xperia Z5.
As usual, the release of the update for these Sony will take place in phases, so it may take a few days or weeks before you receive it. The arrival of Android 5.1.1 for the Sony Xperia Z1 is simple: Android 5.1.1 Lollipop update for Sony Xperia Z1, Sony Xperia Z1 Compact and Sony Xperia Z Ultra is not yet ready, and the development needs some extra time to finish correcting the update.
Therefore, the owners of a Xperia range smartphome that are experiencing problems in the version of Android 5.0.2 Lollipop have no choice but to be patient and wait for the arrival of this new update.
