For security and test review reasons, all video from your secondary camera must be uploaded and accessible. If any video is missing or corrupted, your test will be invalidated.
If you received a message that video from your secondary is missing or corrupted, please follow these steps before testing again:
- Make sure your phone is fully charged or plugged into a charger.
- Set your phone to do not disturb. You should not receive any calls or notifications during the test.
- While setting up your phone as a secondary camera, check your computer screen to make sure the phone video is visible.
- Do not touch your phone during the test.
- Close all other programs running on your computer.
- Make sure you are on an internet connection with at least 2 Mbps download speed and 1 Mbps upload speed. We recommend using a stable, wired ethernet internet connection instead of using Wi-Fi or mobile hotspot services. You can type “internet speed test” into most search engines and find a quick and free way to test your speed.
- Ask anyone else using your same internet network to disconnect while you are taking the test, and disconnect all other devices connected to your internet network.
- Try to take the test late at night or early in the morning, during off-peak network times.
- If you are in China and using a VPN, try re-downloading the desktop app from englishtest.duolingo.com instead of englishtest.duolingo.cn.
