Android N Developer Preview... Overview

The newest version of Android has arrived even earlier than you would expect: welcome, Android N.

N, as in, 'No, even Google has not decided on the name of it just yet'. 

But first, you should know that this is not the final version of Android N: in fact, this is a Developer Preview, a version intended solely for developers and testers to check out on their devices and prepare future apps for the new features that Android N provides. At Google I/O 16, the company unveiled Developer Preview 3, the first beta-grade version of the platform ahead of the final release later this summer.

You can install this beta only on recent Nexus phones (Nexus 6, Nexus 9, Nexus 5X, Nexus 6P, Nexus Player and Pixel C, specifically). So how do you get it? We manually flashed it on our Nexus 6, but the easier way to do it is to enroll in Google's Android Beta Program. Once you enroll, you will get the new Android N Developer Preview via an over-the-air (OTA) update. You can also easily revert to a public Android release without having to go through the hassle of manually flashing anything.

With all this in mind, let's start with the TL;DR: here's all the important new stuff in Android N:

1. Perfromance improvements with a new just-in-time (JIT) compiler that gets rid of super long 'Optimizing apps' screen at startup
2. New multitasking options: split-screen and picture-in-picture
3. New notificattion system with Quick Reply option
4. Quick Switch is like Alt+Tab: double tap the recents button to switch between the current and most recent apps
5. Quick Setting toggles
6. Subheadings for Settings that help you make more sense of them
7. Data Saver
8. Doze now works right after you lock your screen
9. Support for Unicode 9 emoji standard
10. Security-enhancements: file-level encryption and seamless updates

Let's dive in and explore each one in more depth.

1. Multitasking: Quick Switch (Alt+Tab for Android), Split Screen, Picture-in-Picture

While there are quite a few changes in Android N, multitasking is likely to be the one that's noticed most by users. There are three new multitasking feats and we think the first one will make quite the splash: it's called Quick Switch and allows you to double tap the recents button to switche to the app you used before. Yes, that's basically like having Alt+Tab on your smartphone. We've tested the new feature on our trusty Nexus 6 and it is ultra fast and reliable.

Then, there is split-screen multitasking. It has been around on smartphones for quite a while, with Samsung being in the lead there. With Android N, Google introduces native split-screen multitasking. You enable it by long-holding the multitasking button while you are in an app. You will see the button change its icon, splitting in two, and your screen will also divide in two. By default, the screen is split 50/50 between the two apps, but you can re-arrange that so that one app takes up to 2/3 of the screen. You cannot change it any further, but that actually makes sense as chances are that further increases in the split ratio will make one of the apps practically useless. Samsung, in contrast, allows totally free adjustments for the size, and we feel it's a bit over the top, especially if you give a certain app just 20% or less of the screen space.

Good news is that split-screen multitasking on Android N works impressively smoothly. You can simultaneously use both apps (unless one of them is YouTube, which pauses whenever you do something on the other split-screen app) and everything works smoothly without any slowdown or lag.

You can also easily copy and paste text from one window to the other when working in split-screen view and that is a really nice thing to have to boost your productivity.

Nonetheless, we have serious doubts that many people would use the split-screen multitasking on a phone regularly. Yes, it's a cool show-off feature, but it makes much more sense to have it on a tablet. In fact, especially on an Android tablet, where apps are often not optimized for the larger screen and having two split-screen apps at all times can actually look better than having one app with vast amounts of wasted white space.

2. New notification system, quick reply and quick settings toggles

The new notification system is also quite a noticeable change: Google says that some 50% of our notifications come from messengers, and that's why it now smartly bundles those texts into one thread and allows you to send quick replies without having to actually open the app.

Google officially calls these threads 'Bundled Notifications'. You can easily expand the full list of notifications by tapping the expand button or using a two-finger gesture.

The notification card from each app are also neatly arranged one on top the other with very little spacing, so the information density is high and you can easily deal with those tons of notifications that occasionally flood your phone. While thinking about this new way to handle notifications we're amazed how much better the Android operating system is dealing with notifications than iOS, where discarding notifications one by one is a long and tedious exercise in frustration. Great job, Google!

Then, there is the new Quick Reply option for notifications. Basically, it is very similar to the way Apple handles this: you get a notification, tap the reply button and get to type down a reply without having to open the app itself: quick and easy. Not all apps handle it perfectly yet, though, but that's expected since this is such an early build of the platform. You cannot use Quick Reply for emails, unfortunately, you have the Reply option right there, but once you tap on it, you are transported into the Gmail app to compose your reply email. Apps like Hangouts and Skype do support the new functionality.

Another clever new features appearing in the notifications dropdown is the list of quick settings toggles: there's a total of five of them and you can choose which one to be there by simply arranging them first in the list of settings toggles. While some of their functionality is already familiar from earlier Android versions (you can long hold the Wi-Fi icon to get right in the Wi-Fi network selection menu), others are new: the option to tap on the battery icon to see a neat graphical overview of your battery life drain is particularly awesome.

It's worth pointing out that all those new innovations happen with impressively smooth animations. Everything is arranged, re-arranged and moving quickly and stutter-free: the expansion of individual notification and the quick toggles to full settings dropdown. Kudos to Google for doing a great job polishing the experience here, despite this being an early beta. 

3. Under the hood changes: security enhancements

The new notification drop-down and split-screen multitasking round up most of the noticeable visual changes in Android N. There is a whole lot that Google has done to improve the performance as well, though.

First, we ought to mention the focus on security: Google includes file-level encryption rather than block level, which should make it harder to break into Android phones, plus it now better protects from malicious media downloads and there is a more stringent app security check on Google Play.

Also, Android N brings improved battery longevity capacity by implementing aggressive Doze app sleeping that was first introduced in Marshmallow right after you lock your screen. Developers can now embed the feature in their apps. This will prevent apps from constantly waking up in the background and draining battery, and is a clever way to make better use of the battery resource on your phone.

Background work in Android N is also optimized and some other changes come as part of Project Svelte to minimize the RAM requirements for Android phones in order for them to run smoothly.

Android N also introduces a new compiler that will no longer require long 'app optimization' times when you reboot or update your phone. App code will also take less space and app installs will happen much quicker.


Android N brings important and practical functionality: the new Quick Switch and split-screen multitasking, as well as improved notification and quick reply system and a renewed focus on security and optimizing the compiler.

The fact that you can easily download the new Android N Developer Preview over the air is a great option for enthusiasts, and it is also great that most of the features work very smoothly even in this early form.

The only thing that mars our enthusiasm for this new version of Android is the fact that the most popular phones in the family (cough, Samsung Galaxy) will not be in a rush to get this new version. Samsung is taking its time with TouchWiz, and chances are that it might be up to a year until this new version starts arriving on those devices. And that's a pity, but for all else, Nexus users rejoice and let us know which of the new features in Android N you like the most in the comments right below.

You do not have to manually flash the preview... thats the whole point of signing up for the Beta program... it comes as an OTA.

Manually flashing the preview even breaks OTA.

The Android N Easter egg is still the flappy bird (Android) game only at night.

I big thing you did not say about that unlike Samsung and Apple, most apps can be used in multitask mode

YouTube pausing in split-screen is unfortunate, I hope they get that sorted out. Samsung's had that working for what, 4 years now?

It's an alpha build, so there's still tons of work needed

Just out of curiosity, what part screams iOS 9 to you?

8. Hitokage

My guess is the multiwindow, in which case, no, it's more of a Samsung thing. Samsung had multiwindow working back in the days of the S3, if memory serves correctly. If it's the way notifications are handled, then yeah, it's a bit iOSy, though iOS 8 was basically iAndroid. If it's something else, I'm at a loss At this point in the market, this "copying" doesn't matter- innovations and improvements on innovations- and of course cloning- are going to be commonplace, especially now that the market has matured and new features aren't going to stand out as much as fresh.

Hopefully with Google adding so many features to stock Android, OEMs will take less time and effort in getting the latest software version to their devices, as they replace their own solutions with the stock ones. N looks very good so far.

I agree it looks promising, and I can't wait for CM14 to arrive. My KK 4.4.2 stock rom finally went down in flames from too much fun, so yesterday unsatisfied with factory reset I tried CM13 for the first time... What a difference - made my G3 blazing fast! I would say it's almost better than a new phone. Even better I still have root!

Since we are already getting Android N preview, do you think we might get an early new Nexus phone?

12. o0Exia0o

Posts: 903; Member since: Feb 01, 2013

I doubt it. I think that the early preview is more of Google trying to get better stability out of Android builds than pushing out hardware faster....If Google did release new Nexus hardware faster this year that would screw Huawei and LG out of their Nexus run and might deter other OEMs from trying to make Nexus hardware...

14. justrt

Makes sense, but at the same time now that you said that. Maybe Google thought of that and that's why they made that 3-year deal with HTC..

15. o0Exia0o

Posts: 903; Member since: Feb 01, 2013

That could be but that's a mighty big assumption that the rumors of the 3yr HTC Nexus phone deal are true... All I know is that nothing is certain until Google says it is....

I know.. I just wish there was a Nexus phone with a SD820 chip :)

22. sgodsell

If you want a Nexus with a faster processor than the SD 820, then buy a pixel C or the Nexus 9. Both have dropped their prices recently. The Nexus 9 is 533 megaflops, and the Pixel C is running at 1 teraflops.

Nexus 9(Tegra K1) is not faster than SN820.

I reckon it we will get early Nexus devices this year But by early I mean in August Instead of the usual October-November release No way Google will release while Android N is still an alpha/beta build Maybe they will give us a quick demo during IO, although IO is early this year in May

20. o0Exia0o

Posts: 903; Member since: Feb 01, 2013

Well didn't Google announce the 5X and the 6P in late August last year and release them mid to late October?

30. vincelongman

Posts: 5728; Member since: Feb 10, 2013

I was thinking they would be released in August Which is about when Android N should be released I reckon there's a good chance they will be announced at IO in May

Sorry I meant September not August...

are there any bugs at the moment? thinking of putting this on my nexus 5x daily driver

11. Hitokage

Posts: 103; Member since: Mar 01, 2015

Don't use it on a daily driver. It's a beta build, and the first version of it at that. Some people say it's stable enough to use, but I wouldn't do it unless you think it's worth the risks. You could always flash the N beta, but keep a backup of your current Marshmallow build

There are lands of bugs,

My friend has N on his 6P, and he says its mostly bug free. I still wouldn't recommend using it on your daily driver though.

In order to help updates get in to the hands of users fast, Android N had been completely rewritten separating framework from applications including Google apps. This will enable all phones from different manufacturers to be updated very fast. Android headlines had s nice article on this
