How to access the hidden infrared camera on your Pixel 4
The Google Pixel 4 contains a specialized infrared sensor designed for face unlock. This video demonstrates how you can bypass its intended use to capture your own infrared photos and videos.
While the infrared camera is primarily utilized for the device's biometric face unlock feature, it can be repurposed as a standard camera. By using the HedgeCam 2 application, users can access this hidden hardware. The process involves repeatedly tapping the camera switch button—the one used to toggle between front and back lenses—until the infrared mode is activated.
