It wakes the device when it is picked up and light up the display for a few seconds when new notifications arrive. You can view and interact with the notifications on the lock screen without unlocking the device.
What is Ambient Display?
The Ambient display feature was introduced on Lollipop by Google.
You can enable it on Lollipop (and above) with these steps:
Go to Setting > Display.
Find Ambient display and enable it.
If your device is not having Lollipop (or above), then you can get this feature with the help of the Android apps. Let’s get started.
Add Ambient Display to Android
Open AcDisplay app. This app works on both rooted and non-rooted device.
Tap the icon to turn it on.
Now you can see the required permissions: Device admin and Notifications.
Provide both the permissions and turn on the app.
That’s it. You’ve just added Ambient display to your device.
Here are some important settings that you can use to get the most out of this app.
Blacklist (within “Apps” option)
By default, it’ll display only user downloaded apps. If you want it to display System apps, then click the menu and enable System apps.
Tap any app and you can see three options:
Hide – notifications from that app won’t get displayed.
Silent – screen won’t wake up when notifications received for this particular app.
Non-clearable notifies – show ongoing notifications such as from services.
This mode wakes the device when you pick up the phone. It is using the device’s sensor to achieve this.
Follow the below steps to disable Active mode when there is no notification:
Tap on Active mode.
Uncheck “Enable when there are no notifications” option.
You can also check these options:
Click on “Send test notification” from menu to see how this app works.
