When Google released its second iteration of the Android N Developer Preview over two weeks ago, one device was notably missing: the Nexus Player. It was originally available for the Nexus 5X, 6, 6P, 9 (Wi-Fi and LTE), Pixel C, and General Mobile 4G.
The build number is listed as NPC91O, while Developer Preview 2 for the rest of the devices is listed as NPC91K.
There are three ways that you can go about grabbing the new build. If you"re already on the first Preview, you can go ahead and check for OTA updates. If you haven"t installed it yet, you can either sign up for the Android Beta Program or you can flash the image onto your device.
Developer Preview 2 is the second of five monthly Previews that Google will be offering before releasing the final bits in the third quarter of this year. Like Preview 3, it is listed as "incremental update, beta".
