Features of
Android OREO(8.0)
Google is pushing Android 8.0 Oreo to Nexus and Pixel devices as device makers scramble to get their phones updated.
Widgets via app shortcuts
Google has changed the location and appearance of the home screen widget picker several times, and Oreo brings yet another alteration. Tap the icon (wherever it may be), and a panel appears at the bottom of the screen with just the widget or widgets for that app. You can long-press and drag any of them onto your home screen.
Enforce background
limits on apps
Android 8.0 comes with a new raft of tweaks to background processes that prevents apps from bleeding your battery dry. To make this change, open your system settings and go to Apps & notifications > App info. Find the app you want to modify. On the info screen is a link to battery usage. Tap that, and you can turn off the toggle for Background activity.
Snooze
notifications
In Android 8.0 Oreo, you can snooze notifications until later.
When you get a notification you want to snooze, slide it left or right, but don't swipe it away. Tap the clock icon next to the notification, and it will be snoozed for one hour. At that time, the notification pops up again. You can also change the hour timer to 15 minutes, 30 minutes, or two hours by hitting the drop-down next to the hour snooze indicator.
Granular control over sideloading apps
Android 8.0 changes that to make sideloading a per-app setting. It's safer, sure, but it's also a bit of a pain to manage. You can find this menu in Apps & notifications > Special access apps > Install unknown apps.
Customize Notifications
Oreo includes several changes to notifications, including notification dots and notification channels.
Long-press and the notification appears in a popup in addition to the notification shade. Not everyone wants the extra clutter, though. Dots can be disabled by opening the settings to Apps & notifications > App info > [app name] > App notifications. Turn off the toggle for notification dots, and they'll never trouble you again.
The above notification menu is also where you'll find channel controls. It can be accessed via the menu, or you can wait for a notification to pop up and move it aside (just like accessing the snooze option above) and tap the settings icon.
