More power over Notifications

Notifications are more widely classified by this version. You can now separate the notification on the basis of their channels i.e. from which app it is coming.
You can now block or customize a notification. Yu can set a sound, lights, importance. The notification of a channel will behave same way as done. A developer has to create on or more channel so that the setting could work.

Battery life

Google always tries to improve the battery life of the devices where the OS runs. Earlier, Chrome was optimized for better battery performance.
Now there will be limitation for every app who tries to use resources in the background. Now developers need to optimize their apps fpr resource allocation in the background. This will improve battery performance of your device.

Icons Appearance

The appearance of icons can also be changed by the OS. Many times, it happens that the icons look a little odd in the interface. There will be a adaptive icon feature where it will adapt a new look according to the interface.
This is done by a mask which is set by the developer. Using the mask, an icon can change its appearance in terms of colour or shape.


Many times you need to enter the information again & again. Information like login id & password is to be entered repeatedly. Many of us uses autofill aps for the same. Now you don’t need to, autofill feature will handle this in behalf of you.

Picture in Picture (PiP)

This feature was launched in Nougat but only limited to Android TV. Now you can watch a video while doing some other job on the phone. You can send screens to a remote device. We still have some doubts about its working until it comes online.
