Yes, most phone cameras can detect infrared (IR) light. You can conduct a simple test by pointing a TV remote towards your phone camera and pressing any button.

This is because phone cameras lack the filters needed to block IR light, enabling them to pick up wavelengths just beyond the visible spectrum.
