Disconnection After Lock Screen or Screen Off

Cause Analysis and Solutions

Cause

In some Android/HarmonyOS systems, when the phone is locked or the screen is off for a long time, the system automatically restricts background network access for apps to save power, especially more noticeable in Wi-Fi environments. This may cause Cloud Control App to experience remote connection disconnection when the screen is locked or in sleep mode.

Solutions

1. Configure Cloud Control App Settings
   Open Cloud Control App → Go to 「Settings」
   • Enable Scheduled Wake-up: Most device models can restore network connection after the screen lights up.
   • Enable Scheduled Unlock: Some device models require unlocking the screen before network can function properly.
   • Disable Battery Optimization: Ensure the App can continue running in the background.
2. Adjust System Power Management
   Open phone system settings →
   Battery → More Battery Settings → Enable "Always Keep Network Connection During Sleep"
   To ensure the phone maintains stable network even when locked or with screen off.
3. Switch Network Environment for Verification
   Switch to mobile data for testing. Most phones can maintain continuous network connection even when locked or in sleep mode when using mobile networks, avoiding disconnection issues.

Professional Summary

Through the above optimization configurations, Cloud Control App can achieve:

• Continuous Stable Remote Connection: Remains online even when screen is locked or off.
• 24/7 Controllability: Monitor and manage devices at any time.
• Reduced Disconnection Risk: Avoid common issues like "connection failed" or "cannot find device".
