Background restrictions

Check that Phone settings -> Apps -> Sleep as Android -> Battery -> Background restriction state as ActiveAlert can use battery in background for you to run ActiveAlert in the background.

Sleeping Apps

Sleeping apps menu is the sniper’s nest for Samsung’s app killing policies. Make sure to follow the instructions very carefully to prevent the apps from being killed.

  1. Start Device care from phone settings

  1. Tap Battery

  1. Tap the 3-dpt menu > Settings

  1. Disable all toggles (except Notifications)

  1. Tap “Sleeping apps”

Some apps may have an alternate layout, follow steps 1&2 above then continue below.

  1. Disable the option Put unused apps to Sleep .

  1. Remove ActiveAlert from the lists in Sleeping apps and Deep sleeping apps.


  1. Add ActiveAlert to the list in Apps that won't be put to sleep.

Optimize battery usage

Battery optimizations are hidden under each app’s settings section. To disable the optimization for the app, you need to expand the sub-menu, so the list reveals the apps, that are restricted. Open System settings -> Apps -> ActiveAlert -> Optimize battery usage, expand the list, and then set the app to “not optimized” with the toggle.

Android Oreo and Nougat 8+7

App power monitor

App power monitor can be turned off completely, or you can manage the apps individually.
For ActiveAlert to work correctly in the background, you need to whitelist them in App power monitor and add them to Unmonitored apps:

Open the Settings -> Device maintenance -> Battery, and at the bottom you’ll see a list of your most frequently used apps.
Apps that are sleeping will appear in the Sleeping apps list at the bottom (tap it to expand the list).
List of Unmonitored apps is at the very bottom (longer scrolling is needed) - these are apps that you specifically want to exclude (whitelist) from App power monitor evil reach.
When inside the Unmonitored apps menu, you can tap the 3-dot menu to add or delete apps from the list.

Android Marshmallow and Below

On other Samsung phones, the path may look like this:

Phone settings > Applications > select three dot menu (top right corner) > Special Access > Optimize Battery usage > Find ActiveAlert on the list and make sure that it is not selected.

Note: If you enable “Edge Lighting” for ActiveAlert, the app will not be able to wake up your screen. To allow ActiveAlert to wake up your screen, please remove it from the Edge Lighting applications list.
