If your test does not load correctly or certain features are unavailable, the issue is often related to the browser you are using on your primary (laptop/desktop) or secondary device (mobile phone/tablet). Unsupported, outdated, or restricted browsers can block access to the test or interfere with critical functions such as camera, microphone, QR-code linking, and secondary camera streaming. In this article, you’ll learn which browsers and versions are supported on desktop and mobile devices, common browser-related issues, and how to verify that your setup meets the requirements, especially when a mobile phone is used as a secondary camera.

​
✅ Supported Browsers (Desktop)

Use the latest stable version of any of the following:
  • Google Chrome (Recommended)
  • Mozilla Firefox
  • Microsoft Edge (Chromium-based)
Unsupported browsers include Internet Explorer, Opera, Brave, and heavily customized Chromium builds.

Desktop Browser Compatibility Status

📱 Supported Mobile Browsers

If your assessment requires a secondary camera, your mobile phone browser must also meet compatibility requirements. The secondary device is used to stream your environment and must remain connected throughout the session.
  • Android: Google Chrome (latest version)
  • iOS: Safari or Chrome (WebKit-based)
Avoid:
  • In-app browsers (Gmail, LinkedIn, WhatsApp, Facebook, etc.)
  • Private/Incognito mode
  • Android WebView–based browsers

​
Mobile Browser Compatibility Status

Important Notes for Secondary Devices (Mobile)
  • The mobile browser must remain open and active for the entire test
  • Do not minimize, lock, or switch apps once the secondary camera is connected
  • Battery optimization, data saver, and background restrictions may interrupt streaming
  • Always open the QR-code link in a supported mobile browser, not an in-app preview

✅ Final Check: Confirm Your Browser

Before starting your test:
  1. Open your browser on both primary and secondary devices
  2. Visit whatismybrowser.com
  3. Confirm the browser name and version match the supported list
  4. Update the browser if required
Using a supported and up-to-date browser on both devices ensures full compatibility, uninterrupted proctoring, and a smoother test experience.
