The Android 5.0.2 Lollipop firmware update has also started to roll out for the Xperia Z3 Compact. Firmware build 23.1.A.0.690 is currently rolling for the D5803 Xperia Z3 Compact variant in the Nordics and Baltic regions.
Sony has also confirmed in a blog post that the update for other series in the Xperia Z range will commence in “around two weeks time“. Sony doesn’t confirm which handsets are expected to roll first, but we would imagine that the Xperia Z2 would be getting Lollipop next.
