The Android One edition variant of the Motorola Moto X4 has started receiving a new update. Carrying a build number of OPW27.1, it's a major update that brings along Android 8.0 Oreo. In addition, the update also includes the latest Android security fixes. The roll out is inline with the 'end of the year' time frame that was promised by the company when the phone was launched. Given that it's an OTA roll out, it might take time for the update to hit your device, so be patient. Source | Via
