Google announced a lot of exciting things at their Google I/O Conference, one of them being the third developer preview of Android N; which is of course the next version of Android slated for an official release this fall. In this video, we're going to overview all the major new features found in the third developer preview.

So one of the first thing you will notice when you power on your Nexus device running the developer preview 3 (I'm running it on my Nexus 6P, it's the new wallpapers. So you'll see several new wallpapers; all of which consist of key vivid shots of nature. They're very crisp and a couple of them really do take advantage of AMOLED displays.

The notification panel and all that it consists of has received some new improvements. First, you'll see that if we look at our quick settings, there are a couple of new quick settings icons for the Calculator and Night Mode. So we covered the Calculator quick settings in the last dev preview but the Night Mode is most certainly new. It allows you to easily activate Night Mode to save some sleep and view content on your mobile device at night without damaging you REM. Long press on a notification and you'll see options to silence the notifications, block all notifications, or do not silence or block notifications. You can click on More Settings to further specify how you want each app to deal with notifications.

If you have a message in your notification tray, you can reply to said message directly from the notification tray itself. And what's cool is that you actually see a really neat Material Design animation to reveal the text box. It's super clean. I love this feature but I really love the design animation more.

In the System UI Tuner (which is still present in this dev preview), there's a section to power the notification controls. With the power notification controls, you can set an important level from 0 to 5 for an app's notifications. You'll see that each level has details as to how important each notification is under each level. We'll see if this feature is implemented into the final build but for those who really want a lot of control over the notifications, I think you'll really love this feature. And while in its settings you can go to Display > Display Size. You can use the slider to make items on your screen smaller or larger. You have small, default, large, larger and largest sizes.

There's been a host of new improvements made to the Google keyboard. Of course, we have to talk about the new emojis. There's a clown, cowboy, green sick emoji, and there are also new skin colors which you can choose from by long pressing on an emoji. There's also a one-handed mode built into the keyboard which can be selected from long pressing the Enter button. And if you go into Settings > Languages & Input > Virtual Keyboard > Google Keyboard, you'll see a section for themes. You can choose from a variety of themes to obviously change the look and feel of your keyboard. There's some basic color options and you can even upload your own images as well. So it's just one more area where Google is letting you customize to your liking. You've got to love that about Android.

Now we talked about this in the last dev preview but Google did mention it at Google I/O so I did want to bring it up again. If you open up one app and then you open up another, you can double press the multi-tasking button to switch between apps super quickly. It's extremely fluid, extremely fast as you can see here. If you're on a call with somebody for example, you can easily switch back and forth to content you need to relay to someone such as directions and Google Maps or a phone call in Messenger or Hangouts; it's a very welcome feature.

But those are some of the main new features found on the third dev preview of Android N. Some other features worth mentioning that we can't easily show you in a video is no more Android updating screen when you upgrade Android and with that comes seamless upgrades, a feature that allows your device to download and install Android updates in the background. There are instant apps so if you Google the web version of a site within an accompanying app, you'll be taken to the app version of the site even if you don't have the app installed on your phone. We'll definitely check out this feature in detail soon.

Last but not least, is of course, Android VR. We'll cover all these features and more in detail when the final build of Android N is released in the fall.
