How to unlock the infrared camera hidden inside the Pixel 4

Thanks for this. Infrared imaging is a major selling point and I now am higly likely to get a Pixel 4.

Note: this is not thermal imaging.

From the video information:

Camera apps to try:

Open Camera: https://play.google.com/store/apps/de...

Some people are reporting better luck with HedgeCam 2: https://play.google.com/store/apps/de...

Tap the button that is normally for switching between front and back camera. Keep tapping until you get to the IR.
