Troubleshooting FreJun Mobile App Issues

1. "Connection Failed" Error When Making Calls

Cause: Usually caused by network instability, VoIP traffic being blocked, or incorrect app settings.

Steps to resolve:

1. Check your internet connection — switch between Wi-Fi and mobile data and retry.
2. Avoid corporate or restricted networks that may block VoIP traffic.
3. Go to Settings → Apps → FreJun → Advanced → Battery and turn OFF background restrictions.
4. Refer to device-specific battery optimisation fixes: dontkillmyapp.com
5. Log out of the app, close it completely, reopen, and log back in.
6. If the issue persists, uninstall the app, restart your phone, reinstall from the App Store / Play Store, and log in again.

2. Not Receiving Incoming Calls

Cause: Background restrictions, missing permissions, or notification settings blocking the app.

Steps to resolve:

1. Ensure the FreJun app is not restricted in the background — go to Settings → Apps → FreJun → Advanced → Battery → Turn OFF background restrictions.
2. Check that all required permissions are enabled — go to Settings → Apps → FreJun → Permissions and enable:
   • Microphone
   • Phone
   • Notifications
   • Network / Mobile Data
3. Make sure your status in the app is set to Available (not Away or Offline).
4. Ensure you are logged into the FreJun app on your device.
5. Refer to: dontkillmyapp.com for device-specific fixes.
6. Restart your phone and test with a few incoming calls.

3. Poor Call Quality / Audio Issues

Cause: Network instability or insufficient bandwidth for VoIP calls.

Steps to resolve:

1. Run a network stability test for at least 5 minutes: test.vsee.com
   • Call quality prediction should be between Fair to Excellent for a smooth experience.
2. Switch from mobile data to Wi-Fi or vice versa and retry.
3. Avoid making calls on congested or corporate networks.
4. Ensure no other apps are consuming heavy bandwidth in the background.
5. If using mobile data, check your signal strength — move to a better coverage area if needed.

4. App Crashes or Freezes

Steps to resolve:

1. Ensure you are on the latest version of the FreJun app — update from the App Store / Play Store.
2. Clear the app cache — go to Settings → Apps → FreJun → Storage → Clear Cache.
3. Restart the app completely and retry.
4. Restart your phone.
5. If the issue persists, uninstall and reinstall the app.

5. Unable to Log In

Steps to resolve:

1. Verify you are using the correct email and password.
2. Use the Forgot Password option to reset your credentials if needed.
3. Ensure your account is active — contact your Admin or Owner to confirm.
4. Check your internet connection and retry.
5. Try logging in on a different network (e.g., switch from Wi-Fi to mobile data).

6. Microphone Not Working During Calls

Steps to resolve:

1. Go to Settings → Apps → FreJun → Permissions and ensure Microphone access is enabled.
2. Check if another app is currently using the microphone and close it.
3. Restart the FreJun app and retry.
4. If the issue persists on a specific device, test on another device to rule out hardware issues.

7. Calls Dropping Mid-Conversation

Cause: Network instability or background app restrictions cutting off the VoIP connection.

Steps to resolve:

1. Run a network test: test.vsee.com
2. Disable background battery restrictions for the FreJun app (see Section 1).
3. Switch to a more stable network connection.
4. Ensure the phone is not entering power-saving or battery saver mode during calls — this can cut background processes.
