Sony Mobile has started to roll a new firmware update for the Xperia XZ, Xperia XZs and Xperia X Performance, which moves the build number from 41.3.A.0.401 to version 41.3.A.2.24. The latest update adds the 1 December 2017 Android security patch. We have heard of a number of complaints about the Oreo update on the Xperia XZ, particularly around performance and battery life. If this update has improved on these points, do let us know in the comments below.
Thanks Anoop, Arz, Eric, Ilkka, Izzat, Jozef, Mandar, Marco and Yeison!
