Most modern cell phone cameras are not designed to see infrared light directly because they contain infrared filters to improve the quality of the images they capture. However, some cameras lack strong infrared filters or have modes that allow limited infrared light capture, offering a glimpse into the infrared spectrum. To check if your phone can see infrared, try pointing a TV remote control at your camera lens and press a button; if you see the light on your camera screen, your camera can detect some level of infrared light.
