Last week, Google rolled out the third iteration of the Android P operating system dubbed the Android P Developer Preview 3 aka Android P Beta 2 (b/c the Android P DP2 was considered to be the first beta release). We still don’t know what the letter P stands for but have a fair idea about the changes that it brings to the table. As always, the Pixels were first to get the update, with others OEMs to follow suit soon. Today, Sony announced that the Android P Beta 2 is ready for the Xperia XZ2. According to their post:

A few weeks ago we announced the release of Android P Beta for Xperia XZ2 devices. Today we release the Android P Beta 2 software. If you already have previous Beta version flashed on your Xperia XZ2 device you’ll get an over-the-air update. If not, visit our Android P Beta site to see how to get started.
