Android 7.0 "Nougat" is a release of the Android operating system. First released as an alpha build on March 9, 2016, it was officially released on August 22, 2016, with Nexus devices being the first to receive the update.
Android Nougat is rolling out to Nexus devices via an OTA update. You'll get this update soon if you have any of the following devices: Nexus 6P, Nexus 5X, Nexus 6, General Mobile 4G, Nexus Player, Nexus 9, or Pixel C.
The simplest way to get the update is to wait for it to show up on your phone, or check for the OTA update manually:
How to download Android 7.0 Nougat via OTA updates
Over-the-air (OTA) updates is the easiest way to download Android 7.0 Nougat. Follow these steps to check if you've received the update.
Open Settings > About > System updates.
Tap Check for updates.
If the update shows up here, you can download and install Android Nougat on your Nexus device. If it hasn't showed up, you should ideally wait until it does.
How to download Android 7.0 Nougat via Android Beta Program
If the OTA update hasn't appeared yet, you can try installing Android 7.0 Nougat via the beta program. The release build is available for some devices such as the Nexus 6P, Nexus 5X, Nexus 9 (Wi-Fi), and Pixel C via this method.
We strongly recommend that you back up your Android device before attempting an update. For devices that don't have the release build, this method will install a preview version and you could lose data and apps could stop working properly.
Visit g.co/androidbeta on your desktop or mobile browser.
Sign into your Google account associated with your eligible Nexus device.
Scroll down and tap Enrol Device. Once you're enrolled, go to Settings > About > System updates.
Now you'll see details about the update including a build name in the second line. This appears in brackets after Android N.
The release build name is NRD90M for Nexus 6P, Nexus 5X, Pixel C, and Nexus 9 (Wi-Fi). If the build name on your device starts with NP, it's a preview build, and we suggest you don't install it.
To remove your device from the beta program, go to http://g.co/androidbeta,sign in and tap Unenrol Device. If you've updated to a release build of Android 7.0 Nougat, unenrolling your device will not remove the update.
