Huawei / Honor

EMUI (and MagicUI on Honor) has multiple layers of battery management that can prevent background apps from running. Follow all the steps below.

Step 1: Configure App Launch Settings

1. Open Settings
2. Tap Battery (or Battery & performance)
3. Tap App launch (or Launch)
4. Find Auto Call Scheduler
5. Toggle off the "Manage automatically" switch
6. In the popup, enable all three toggles:
   • Auto-launch
   • Secondary launch
   • Run in background
7. Tap OK

This is the most important step on Huawei/Honor devices.

Step 2: Ignore Battery Optimization

1. Open Settings
2. Tap Battery
3. Tap Battery optimization (you may need to tap the gear icon)
4. Change the dropdown to All apps
5. Find Auto Call Scheduler
6. Tap it and select Don't optimize
7. Tap OK

Step 3: Lock the App in Recent Apps

1. Open your recent apps
2. Find Auto Call Scheduler
3. Swipe down on the app card to lock it (a lock icon appears)

This prevents the system from clearing the app when you clean recent apps.

Verify It's Working

1. Create a test schedule set 2-3 minutes in the future
2. Close the app completely (swipe from recent apps)
3. Lock your phone
4. Wait for the scheduled time
5. If the call triggers, your settings are correct

If it still doesn't work, see Calls Not Triggering for additional steps.
