Android Pie updates continue to roll out, and next up is Sony, which is starting to bring the latest version of Google’s mobile operating system to its older devices, the Xperia XZ2 and XZ2 Compact, via Xperia Blog.

Technically, the Xperia XZ3 that Sony announced at IFA is the company’s first Android Pie device, but the Xperia XZ2 and XZ2 Compact (which, incidentally, are very similar devices to the XZ3) are the first phones that Sony is actually updating to Pie, instead of merely shipping with the software already installed.
