As is the norm before a commercial release, Google has published the Developer Preview version of Android 7.1 Nougat. For now, this preview build is only compatible with the Nexus 5X, Nexus 6P and the Pixel C. Since this is meant to be a developer only build, there are bound to be some errors and minor bugs with this build, so it’s not recommended if you use either of these devices as your daily driver.
Android 7.1 is already running on the recently launched Google Pixel and the Pixel XL, but is yet to be made available for the rest of the Nexus family. Although manufacturers are already working on the Android Nougat update, they’re yet to begin development on Android 7.1. This means that upcoming Nougat updates will be Android 7.0 and not 7.1.
This could further dampen the spirits at Google, who have been haunted by the ghosts of fragmentation since the inception of Android. We’re yet to get a detailed understanding of how Google intends to fight this, but things don’t seem to have changed much over the past couple of years.
To be eligible to receive the Android 7.1 dev preview for your compatible devices, you can sign up for Google’s Android Beta Program. The Developer Preview will be sent out to the older Nexus devices soon, but the company has failed to give a provide a date or month.
