The Sony Xperia XZ Premium, Sony Xperia XZ1, and Sony Xperia XZ1 Compact will receive Android Pie starting October 26. Similarly, Owners of the Sony Xperia XZ2 Premium will be receiving it from November 7. The company has stuck to its promised schedule so far, so we’re confident that the updates will start hitting the devices at the specified times.
