Install It If You Use Always On Display
If you use the Always On Display feature on your Galaxy S7 or Galaxy S7 Edge you're going to love Android Nougat because it comes with some useful upgrades.
Once you install Android Nougat on your Galaxy S7, Always On Display will be able to display notifications for first-party applications and third-party apps. This is useful is you're reliant on popular third-party apps like Gmail to get you through the day.
This feature also works with other popular applications like WhatsApp, Facebook, and various weather applications.
There are also some new clock styles included in the update and you can also customize the display with your favorite images. To do that you simply need to pick an image from your Gallery.
If you're tired of the default AOD look, you probably want to download Nougat.
