Android 7.0 was officially released on August 22, 2016, with the Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, Nexus Player, Pixel C and General Mobile 4G as the first devices to receive the update
On September 6, 2016, LG announced the V20, the first smartphone to ship with Nougat pre-installed. Google unveiled the first-party Pixel and Pixel XL smartphones during a hardware-focused event on October 4, 2016.
Updates to existing devices vary by manufacturer and carrier, and driver support for the version by the manufacturer of a device's respective system-on-chip. Major manufacturers, including HTC, Sony, and Motorola announced intents to update a range of their recent devices to Nougat.Qualcomm stated that it would not support Nougat on devices using its Snapdragon 800 and 801 system-on-chips for undisclosed reasons. Although developer preview builds of Nougat were released for the device, Sony stated that it would not upgrade the Xperia Z3 (which uses the Snapdragon 801) to the final version due to "unforeseen platform limitations". It was reported that the Google Compatibility Test Suite (whose tests must be passed in order to receive official certification) specified that all devices running Nougat must support either Vulkan or OpenGL ES 3.1 graphics APIs — neither of which are supported by the device's Adreno 330 graphics core.
Android 7.0 - 7.1.2 "Nougat" (codenamed Android N during development) is the seventh major version of the Android operating system. First released as a beta build on March 9, 2016, it was officially released on August 22, 2016, with Nexus devices being the first to receive the update, though the LG V20 was the first new smartphone released with Nougat.
Android Nougat introduces a split-screen display mode for phones, in which two apps can be snapped to occupy halves of the screen. An experimental multi-window mode is also available as a hidden feature, where multiple apps can appear simultaneously on the screen in overlapping windows.
The notification shade was redesigned, featuring a smaller row of icons for settings, replacing notification cards with a new "sheet" design, and allowing inline replies to notifications (this feature is implemented via existing APIs that are used for similar functionality on Android Wear). Multiple notifications from a single app can also be "bundled", and there is greater per-app control over notifications.
The "Doze" power saving mechanism introduced in Android Marshmallow was expanded to include a state activated when the device is running on battery and the screen has been off for a period of time but is not stationary. In this state, network activity is restricted, and apps are granted "maintenance windows" in which they can access the network and perform background tasks. As in Marshmallow, the full Doze state is activated if the device is stationary with its screen off for a period of time. A new "Data Saver" mode restricts background mobile data usage, and can trigger internal functions in apps that are designed to reduce bandwidth usage, such as capping the quality of streaming media.
Platform:
In December 2015, Google announced that Android Nougat would switch its JRE (Java Runtime Environment) from the defunct Apache Harmony to OpenJDK—the official open source implementation of the Java platform maintained by Oracle Corporation and the Java community. The Android Runtime (ART) now incorporates a profile-guided compilation system, utilizing a JIT compiler and profiling alongside its current ahead-of-time compiler to further optimize apps for a device's hardware and other conditions in the background.
On devices shipping with Android Nougat, the "Verified Boot" policy (introduced partially on KitKat, and displaying notifications on startup on Marshmallow) must be strictly enforced. If system files are corrupted or otherwise modified, the operating system will only allow operation in a limited-use mode or refuse to boot at all.
