While there are still many handsets shipping with Android Marshmallow these days and most Android devices capable of running it are still waiting for their Android 7.0 Nougat update, Google Pixel and Pixel XL are set to become the first smartphones to ship with Android 7.1 later this month. However, the most recent Nexus phones and the Pixel C slate are scheduled to get updated as soon as possible.
Google Nexus 5X and Nexus 6P, as well as the Pixel C tablet and other devices that would get Android 7.1 Nougat are expected to get the following main improvements: seamless updates, moves (swipe using the fingerprint reader), night light, and “Daydream VR” mode. The minor improvements include better touchscreen performance, support for circular app icons, a new storage manager, and more.
The first Android 7.1 developer preview should become available by the end of the year, while the public release will probably arrive in the first part of 2017. Unfortunately, it is not clear yet if earlier devices like Nexus 9 will also get Android 7.1.
