After announcing their new operating system, Android 7.1 Nougat, Google said that it will start rolling out to Nexus devices in the first days of December, but didn’t mention and exact release date. However, users should start getting the notification through the next days, as some carriers have already announced specific dates.
Vodafone Australia, for example, is planning to release Android 7.1.1 for the Nexus 6P on December 6, the update having a total size of 650 MB. Also, besides the new features brought by Nougat, it will include the December security patch. All eligible devices in this region will get the update until December 20.
As for the rest of the devices, like Nexus 5X, 6, 9, Nexus Player or Pixel C, they will also start getting the update at the same time, all over the world. Pixel and Pixel XL, which already have Android 7.1, will receive just security updates in early December.
As soon as you get the notification to update your phone to the latest version, make sure your phone is fully charged or plugged in, in order to avoid an accidental shutdown during the process. Also, make sure any important data, like photos, contact and messages, are backed up, as you might lose them.
Recently, the Android 7.1 Developer Preview for the Nexus 6P and 5X was released, for those who want to test the new features before the over-the-air update is available. If you want to check out the new features, it can be downloaded from here.
