Google recently released factory images of Android Oreo of it’s entire line of devices but the Nexus Player (2014) wasn’t shown much love. Considering that, it’s a miracle its still receiving software updates. The Nexus Player was slated to receive Android O Developer Preview, earlier this year. But, the update was delayed because a bug that started uploading data automatically was found in the build.
The bug was found in later stages of development and so this led to the delay of the Android 8.0 build, Android Police was told. Now, that the fix is complete, the Android 8.0 Oreo build for the device is now available finally.
Anyways, the build is there in OTA as well as Factory images and the build number is OPR6.170623.021. Recent OTAs and factory images for other devices were also uploaded, which you can find linked in this article here. If you don’t know how to flash these, you might as well stay put until Google pushes an OTA.
