Sony rolling out Android Lollipop 5.0.2 updates for Xperia Z and Z1 series devices
17

The Xperia Z1 changelog contains the following fixes and improvements:
- The lock screen / notification bar doesn’t indicate “no service” when the device has coverage
- The “close-all-button” in the activity menu has been brought back, so you can easily close all apps at once
- Devices with server policies (such as Exchange Active Sync for e-mail) have been unblocked to enable the new Lollipop lock-screen notifications
- The LED light is lit across all sound modes, no longer offset by “silent”
- Made the necessary fixes to enable the easy movement of content from internal memory to external microSD card
- Improved messaging functionality in Ultra stamina mode
Meanwhile, the update for the older Xperia Z series (a 1.2GB mammoth of a download) contains Lollipop's most notable additions, that is Material Design, lock screen notifications, user profiles, and moving apps to SD cards.
