Sony is busy pushing a new set of security updates for its Xperia XZ and Xperia X performance smartphones.
The update contains patches as part of the monthly Android Security patch level update which brings it to 1st January 2017. There doesn’t seem to be any new feature addition apart from the usual stability improvements and bug fixes.
The new update is available on both the single-SIM and dual-SIM variants of both the handsets mentioned above i.e. Xperia XZ and Xperia X Performance.
After the successful install, it will push build number from 39.2.A.0.374 to 39.2.A.0.386, as shown in the screenshots above.
