Data Saver is a handy feature you can use when running low on the monthly data allotment for your wireless plan. When enabled, Data Saver will prevent apps from using cellular data in the background. Meaning, Twitter and Facebook may not refresh in the background very often, if at all.
However, if there's an app or six you want to grant permission to keep using data when Data Saver is enabled, you can do just that.
Open the Settings app, tap on Data usage > Data Saver to enable the new feature and tailor which apps are allowed to ignore the setting.
When you receive a new message in apps like Messages or Facebook Messenger, you will see a new reply option at the bottom of the alert. Tap on it, type your message, and go on about your business without ever leaving the current screen.
Better yet, your replies are added to the notification so you can keep the conversation going.
The Settings app received a facelift. The top of the page will offer suggestions and toggles for items you may want to setup or disable. You can now slide out a Settings menu from the left side of the display to jump between different categories with minimal effort.
Android now supports viewing two apps at the same time; even on phones. A long-press on the multitasking button will shrink down the app you are currently using, and give you the option to pick from another app that's open in the background. Alternatively, press the home button to pick an app from the home screen or app drawer.
Adjust the size of each app by dragging the handle in the middle of the screen.
A second swipe down on the screen when notifications and quick settings are present will reveal a series of Quick Settings Tiles. These tiles act in a similar fashion to the smaller version from the previous slide, with a tap toggling the corresponding service or setting and a long-press providing more options.
Tap on the Pencil button near the top of the screen to rearrange, delete or add new tiles. Notice you can have multiple pages of tiles with swipe left or right.
Night Light mode on Android Nougat turns your display an amber color.
The jury is still out regarding whether or not the feature helps you fall asleep easier, but one thing is certain, it does cause less eye strain in dimly lit environments.
Open Settings > Display >Night Light to enable the feature.
Depending on customizations made by the manufacturer of your phone, you should have options ranging from manually enabling it to setting Night Light automatically turn on from sunset to sunrise using your location. Another name used by device makers is Night Mode.
Starting with Android 7.1, a long press on an app icon will reveal Android's App Shortcuts feature. These shortcuts range from features such as quickly composing an email in Gmail, to clearing up storage from the Photos app.
