Two Japanese carriers, NTT docomo and au by KDDI, have announced their OS schedule and with it, which Sony Xperia devices they plan to update to Android 5.0 Lollipop. Unlike the global rollout, the only Xperia Z users that will see Lollipop in Japan are those carrying an Xperia Z2 or Z3 series device. There is no timeline on when Lollipop will roll out for these models.
Therefore Xperia Z, Z1, Z1 f, Z Ultra and Tablet Z owners are out of luck. Let’s not forget the other models outside of the Z series in Japan like the Xperia A, A2 and UL. This is the issue with carrier devices, updates are at the whim of the operator. Makes us appreciate Sony updating the entire Xperia Z line to Lollipop even more.
