Android 8.0 Oreo vs Android 7.0 Nougat Walkthrough: What to Know

And Much More

These are just a few of the biggest changes visually, or that will impact users the most that we can actually show you. 

However, there are dozens of extremely important features that aren't visible to the end user, so we can't compare the two. Here's a list detailing a few of the biggest changes. 

System optimizations so apps load faster and phones reboot twice as fast. Background limits control what apps use and can access the battery, especially when the app isn't open. This will really improve battery life as apps you're not actively using will still be ready to open, but won't drain the battery. 

Google added wide-color gamut support for apps, improved keyboard navigation, and even new low-latency audio system. Not to mention Bluetooth aptX and other audio improvements. A big talking point for Google is Vitals. This project improves battery life, startup time, graphics rendering time, and device stability. 

Oreo has downloadable fonts and XML files. Then there's something called Project Treble to help with Android software updates. After Oreo, manufacturers will be able to update to the latest version of Android faster than ever before, as Treble makes updates modular and splits the important parts up. Meaning Samsung won't have to completely redo its entire Samsung UX for the Galaxy S9 to upgrade to Android P later this year. Well, that's the hope, at least. 

There's also something known as the Visual Core. This is Google's brand new system for improved photography and HDR+ photo modes. It's only available on the Pixel 2 and Pixel 2 XL, unlocking a new Pixel Visual core processor inside the phone. However, we're expecting visual core to expand to other devices in the future.

You'll find fingerprint gestures built into stock Android now, and much more. And finally, Android GO is an initiative to deliver a lighter experience for budget devices. There are a few excellent Android GO devices available as we speak. This image teases just a few of the dozens of changes in Google's new software.
