Sony promised to update its Xperia 10 II and Xperia 10 III phones to Android 12 and after finishing the with the latter it’s now serving the first batch of updates to the Mark II.
The OTA update seems to be limited to just South East Asia, at least for now. The update package itself is 900MB big and has a build number 59.2.A.0.422. The security patch is from March 2022 instead of February 2022, which the Xperia 10 III got.
This is clearly just a soak test, but we are pretty sure that the global distribution of Android 12 is just around the corner.
