Just a day ago, we‘ve informed that Sony has released May 2018 security update for Xperia XZ, XZs and X Performance handsets. Now they were expanding the availability of this may patch to more Xperia range devices. The following lists of handsets are getting this update – Xperia XZ1, Xperia XZ1 Compact, Xperia XZ Premium, Xperia X and Xperia X Compact.
The build number for XZ Premium, and XZ1 series will be in 47.1.A.12.179. Other two handsets Xperia X and X Compact will receive this update as 34.4.A.2.70. Apart from the May 2018 patch update, it doesn’t bring any new features for these devices.
If you own any of the above mentioned handsets, you will receive this security update automatically via OTA. Because of batch-wise roll out the firmware will take some time to hit all handsets. If you can’t stay calm, then check for the software update manually from Settings menu.
