Top 5 new features of Android Oreo

Oreo isn’t just meant for developers looking to improve their apps anymore. After months in beta, you’ll soon be able to download the full version to an array of Google’s own devices, including the Pixel, Pixel XL, Pixel C, Nexus 5X, Nexus 6P, and Nexus Player. 
1. More Notification Controls
Thanks to a new feature called notification channels, you’ll be able to customize certain kinds of categories of notifications from apps – that way, you can block some less-useful notifications and ensure that only the essential ones pull you out of your daily routine. This could be handy with filtering notifications from certain conversations in messaging apps, for example.

2. Picture In Picture Mode
Oreo will provide a native picture-in-picture framework for video apps, allowing users to continue watching footage in a small window while navigating elsewhere.
This will be handy for continuing to watch, say, a YouTube clip or Netflix TV episode while reading email, summoning an Uber car, or navigating around the OS. Granted, the window will be absolutely tiny on your average smartphone, but it’s still better than having to stop and start every time you need to do something else on the screen.

3. New Emojis to select from
Emoji on Android will now look much similar to what they appear on Apple’s iOS. Earlier, Google used “Blob faced emojis.” With Android 8.0, Google has announced full compatibility with Emoji 5.0, which comes with a slew of new emoji such as orange heart, dinosaurs, and vomit face. This is a love it or hates it change, I much prefer the new skin pack of emoji.

4. Fingerprint gestures
A lot of OEMs allow users to do a lot more things like taking selfies and navigating the UI with the fingerprint scanner besides unlocking/locking the smartphone. Android O now allows developers to include native fingerprint-based gesture controls.

5. Background apps notification
While having a quick and easy way to see which apps are running in the background (and potentially draining your battery) sounds like a good thing, the implementation introduced in developer preview 3 is less than ideal.
An Android system notification lives in your tray near-permanently, constantly reminding you how many apps are running in the background.
