Sony users of the Xperia Z5, Xperia Z3+ and Xperia Z4 Tablet were having troubles with updating their devices until the middle of the summer, but now the Japanese manufacturer moved on and issued a new software update, bringing some security patches.
The size of the update is 400 MB and at first glance doesn't bring any dramatic feature or UI changes. Some suggest the battery and heating issues have been cleared out, but we are yet to get a confirmation.
