Sony has reportedly released the Android 5.1.1 Lollipop update for the Xperia Z lineup of handsets, including the Xperia Z1, Xperia Z1 Compact and Xperia Z Ultra.

Only last week, Sony’s Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z got updated to the Android 5.1.1 Lollipop. But now, the same update is being rolled out to the Xperia Z1, Xperia Z1 Compact and Xperia Z Ultra smartphones as well, according to Xperia Blog. Although These devices are comparatively old, Sony is generous enough to support them in 2015.t

Once the users of the Xperia Z1, Xperia Z1 Compact and Xperia Z Ultra update to the Android 5.1.1 Lollipop OS, the devices should show the build number: 14.6.A.0.368. In any case, readers should note that the Lollipop firmware has been sent out in phases. As of now, the update has reportedly reached only a few locations. Therefore, Xperia Z device owners are requested to wait for the OTA update in the following weeks.

Technically, the new Android 5.1.1 Lollipop update fixes the “Stagefright vulnerability.” For those unfamiliar, the Stagefright is a critical vulnerability that impacts nearly 950 million Android devices world-wide.

According to GSM Arena, this package also comes with extra options in the notifications menu for Wi-Fi and Bluetooth. A slew of new themes and settings icons have also been added, along with the ability to integrate LinkedIn with the Calendar and Contacts. This update enhances the camera focus, improves speed and accuracy.

In addition, the volume, alerts and silent mode control have apparently been fine-tuned. Several improvements targeting the Business, Enterprise and Calendar have also been included, allowing users to share the calendar events/agenda instantly from email. To top it off, the Sony SmartWatch 3 can be used as a remote shutter button for the camera unit of the Xperia handset.
