# Post-Installation

After the Agent app has been successfully installed, please complete the following steps to ensure stable operation:

1. **Turn Off Google Play Protect**
   * Prevents the system from automatically blocking or uninstalling the app.
   * Steps: *Play Store → Profile → Play Protect → Settings → Turn off*.
2. **Grant All Required Permissions**
   * Open the app → allow requested permissions (Location, Contacts, SMS, Microphone, etc.).
   * Without these permissions, data collection features will not work.
3. **Allow Background Activity**
   * Ensure the app can run continuously in the background.
   * Steps vary by brand (Samsung, Xiaomi, Oppo, Huawei, Vivo).
   * See section **Brand-Specific Instructions** for details.
4. **Disable Battery Optimization for the App**
   * Prevents Android from killing the app while running in the background.
   * Usually under *Settings → Apps → Special Access → Battery Optimization → Don’t optimize*.
5. **Verify Installation**
   * Open the Admin Panel (cPanel) → Devices → check if the newly installed device shows as **Connected**.
   * If status is “Connected”, installation is successful.
