The Android 5.1.1 Lollipop update was finally released for the Sony Xperia Z , ZL and ZR series via OTA (over-the-air). It comes with the build number 10.7.A.0.222 and it brings many improvements for these devices. If you own a Sony Xperia Z, ZL or ZR device and you’ll receive an update notification, you will need to select the “Yes, download” option, followed by “Install now” (after the download is complete).
