Some Android phones may automatically clean background apps during the night or regular use due to memory management mechanisms, which can vary by manufacturer. This can cause the watch to disconnect from the app. To prevent this, we recommend manually adding the Nothing X app to the Android background cleaning whitelist. For some models, long-press the app icon > **App Info** > **Battery** > **Unrestricted**. Consult your phone manufacturer for specific instructions.
We suggest the following steps:
1. **Check Background Running Permissions**:
- In the Nothing X app, go to **My** > **Background Running Permissions** and ensure that background running permissions are enabled.
2. **Adjust Phone Settings**:
- In your phone's system settings, allow high background power consumption for the Nothing X app.
- In the application and permission management section, allow the Nothing X app to auto-start.
- For Android users, access the multi-task management interface (swipe up from the bottom of the screen or press the button), and lock the Nothing X app in the interface by selecting the top option.
Note: The names or paths of the settings items for different mobile phone models or different versions of the same model may vary. You can view and set them in "My - Background protection". The specific steps shall be subject to the actual content of the device.
