✅ Common causes and fixes
| What might be wrong | How to fix it |
|---|---|
| Camera permission not granted to the browser or camera app | Ensure camera access is allowed on your phone for the browser or camera app used to connect the secondary device. Android: Settings > Apps > Browser (Chrome) or Camera app > Permissions > Allow Camera. iOS: Settings > Privacy & Security > Camera > Enable access for the relevant browser or scanning app. Close and reopen the app, then re-scan the QR code if prompted. |
| Camera permission blocked after first attempt | If camera access was denied earlier, the phone may continue blocking it. Android: Settings > Apps > Browser > Permissions > Camera > Allow. iOS: Settings > Safari (or relevant browser) > Camera > Allow. Restart the browser and reconnect the secondary camera. |
| Camera app or browser closed or minimized | The secondary camera must remain active throughout the assessment or interview. Keep the camera app or browser open and in the foreground. Do not switch apps, lock the screen, or minimize the browser once the session has started. |
| Screen auto-lock or battery saver enabled | Auto-lock or power-saving modes can interrupt the camera feed. Disable auto-lock or extend screen timeout. Turn off Battery Saver / Low Power Mode. Keep the phone connected to a charger for the entire session. |
| Unstable or weak internet connection | A poor network can cause camera freezes or disconnections during monitoring or interviews. Use a stable Wi-Fi connection where possible. Avoid switching between Wi-Fi and mobile data. Move closer to the router to improve signal strength. |
| QR code session expired or camera disconnected | If the camera disconnects, follow the on-screen instructions on your primary device. Re-scan the QR code to reconnect the secondary camera and resume the session as instructed. |
| Camera lens blocked or incorrect phone positioning | A blocked or unclear camera view may affect monitoring or interview visibility. Remove any covers, stickers, or accessories blocking the lens. Position the phone in landscape mode on a stable surface with a clear view of you and your primary screen. |
| Phone overheating during extended use | Long camera usage during assessments or interviews may cause overheating. Remove the phone case if needed. Keep the phone in a cool, ventilated area away from direct sunlight. Close background apps to reduce load. |
| Multiple apps accessing the camera | Other apps may interfere with camera access. Close video calling, social media, and camera-based apps before starting. Restart the phone to clear background processes, then reconnect the secondary camera. |
| Outdated or unsupported phone software | Older operating systems may not support continuous camera streaming. Android: Settings > Software Update. iOS: Settings > General > Software Update. Restart the phone after updating and reconnect the secondary camera. |
Additional tips:
- Restart your mobile phone before the exam to clear background processes
- Remove any phone case or cover that may block the camera lens
- Avoid notifications, incoming calls, or switching apps during the exam, as this may disconnect the camera feed
