Sony has started rolling out a new update to its Xperia XA Ultra smartphone. It's a minor update that arrives as build number 36.0.A.2.146 for the single-SIM variants and 36.0.B.2.146 for the dual-SIM variants.
Sadly, the official change-log isn't currently accessible, so it's difficult to say exactly what changes the update brings along.
As is usually the case with OTA roll outs, it may take some time for the update notification to pop up on your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu.
