1) Multi Window
Multi window ia feature which allow you to run 2 apps side by side on a single screen. This feature was first introduced by the samsung in Galaxy S3 and later was implemented by some other companies too. Although using multi window on a small screen is not useful but with larger 6-inch screen size is good. The multi windows are re-sizable too.
2) Direct Reply to Notifications
With this feature you can directly reply to a native notification with out opening the respective message app. This will reduce the time in replying to a message and don’t interfere with the current running app. All you need is to pull down the notification panel and click on reply to the notification. This feature will also ease on the RAM management because apps will not run in background memory for long time.
3) Quick Setting Shortcut
Easy access to Bluetooth, Wi-Fi, and the flashlight with a single swipe. Not only are all the important shortcuts now all in the notification shade, but it’s something you can edit to change the order of the icons.
This is something that the different OEMs have had to implement in the past, with mixed results – as default Android behaviour, it’ll help ensure that users of all devices get the same kind of experience.
4) Multi Locale Support
This feature will be useful for multilingual users. You can now select multiple locales in your settings, and this can be used by apps to tailor their content. for example, your search engine results could be tailored to show results in all the languages you selected.
5) More Battery Life
Doze a feature on android which saves the battery when the phone is in idle condition introduced last year. This feature has been updated and now can save the battery while the mobile in use too.
6) Direct Boot Mode
Direct boot mode is some what like safe mode but will allow user to boot in secured zone without device unlocked. Apps do not run during direct boot mode but can use some components like alarm or important notifications for the user. Other security updates include file based encryption, and seamless updates, which will lead to faster software updates in the background.
7) Virtual Reality
Nougat is also bringing virtual reality mode as stock but through Daydream. Current phones are not expected to be compatible with Daydream so this will matter only to people buying new device with Android 7.0 as stock OS. Although Daydream-ready phones, headsets and controllers, are all coming later this year.
8) Better Performance
Android 7.0 Nougat comes with a new feature called Vulkan, a cross-platform API for 3D graphics. This makes better use of multi-core processors for gaming and other similar applications, so expect a performance boost over time. There are also optimizations to the way apps run in the background, which will also improve system performance by preventing needless access to the RAM.
