Just over a month ago, Sony Mobile commenced the Android 9 Pie rollout for the Xperia XA2, XA2 Plus and XA2 Ultra with build number 50.2.A.0.342. It was only out in one region (Russia), but was found to brick devices. Well now the Android Pie update has resumed with new build number 50.2.A.0.352. The update comes with the March 2019 Android security patch. If you have downloaded the new update please let us know your experiences in the comments below.
Thanks Aungtinwin and Diogo!
