Swiping the notifications gives you two options – 1. Accessing the notification 2. A clock for snoozing it.

App Badges –  Android O adds supports for app badges known as Notification dots. These are a numbered bubble showing the unread notifications of the app.

Setting Menu –  This the place where maximum visual changes take place. Both for Pixels and Nexus there are new color schemes available. In this First Developer preview hamburger menu and slide -out navigation drawer have been removed.

The setting menu is much shorter when compared with Nougat and this is one of the major change, with no categories like personal & system, Wireless and networks,devices. Instead of that Android O has connected devices, Networks and internet, security and screen lock. Everything is in their places with a small changes.  The things that you know in Nougat exist in Android O, but you need to dig a lot to find it. Without Interminable In Android O Google has grouped things that makes more sense.

System UI Tuner –  According to your personal preferences you can tweak certain things by enabling System Ui Tuner as that of Nougat. In order to enable it you need to swipe down the notification shade or long press the status gear icon.System UI tuner lies under settings – system in Android O.  It includes four areas, status bar, lock screen, navigation bar and Do not disturb.

Status bar –   With the aid of toggles you can enable or disable icons in the status bar. So, if you wish you can remove hotspot icons or bluetooth as you wish. Displaying the battery percentage in battery icon will no longer be available in Android O. In Android O  enabling the “ always show percentage will keeps the percentage visible.

Navigation bar –  Navigation bar contains a bunch of options in Android O, a layout options helps in choosing compact , normat, right-learning or left-learning.

Lock Screen –  Lock Screen is same as that of Nougat, having options in system UI. There are huge number of options making us to think a perfect Android 8.0 feature. Ambient Display have also been updated.

Notification Channel –  Notification channel allows you to split your notifications in various themes. In Android O Notification channel allows you to get a direct reply channel, instead of receiving dozens of channels from twitter.

Audio –  For Android O,  Sony donated its LDAC Codec to Google. If you have LDCA bluetooth headphones you will get better quality in 8.0.

Limiting Background Process –  Many features has been added to limit the battery drain amount and the apps that were allowed in the background.

Adaptive icons – Adaptive icons are a favor method for saying that Google is making an endeavor to clean up the chaotic situation of conflicting application icons in Android. They fundamentally furnish application designers with numerous shape formats for every icon that adjust to the gadget they show up on. So if the default application icon shape for your telephone is a rounded square at that point that is the thing that you’ll see no matter how you look at it. Shake a Pixel with roundabout icons and you’ll never again observe irregular square icons blended in with all the round ones. On that note, the nav catches change from white to dark when opening the application drawer now as well.

Autofill API –   It helps in Managing the passwords and data in a more better way than any other versions. Google in its blog states  “ Similar to keyboard app you can also select autofill app”. This autofill stores user data like, usernames, passwords, address and other things.

More Color gamut for apps –  Android O gives more support to colors for apps, similar to that of HDR for app developers.


Completing some of the works that were started in Nougat release and Android O is following very much in Nougat footstep. Permission Management and User facing notifications are much better when compared before. Android O is catching up with a lot, from autofill APIs, adaptive icons, Picture-in0-picture mode, navigation bar and app badges.
