OnePlus 8 Pro's Color Filter lens can see through some plastic objects
Prima facie, the OnePlus 8 Pro's quad-camera setup is only marginally different from that on its predecessors. Nobody quite understood what the 5MP Color Filter sensor's purpose was, and rightfully so. It doesn't do as much heavy lifting as the telephoto or wide-angle lens. However, popular YouTube content creator MKHBD found a rather interesting use for the sensor.
Marques demonstrates the OnePlus 8 Pro's Colour Filter sensor's ability to see 'through' some plastic objects on his Twitter. He claims to have tried it with several types of plastics, and concludes that it only work with materials that do not have IR shielding. In the video attached below, you can see that applying the 'Photochrom' mode in the camera app allowed him to see through the trigger button of a VR controller. Further down in the Twitter thread, another user points out how prolific leaker IceUniverse was able to see through what appears to be a media control panel of sorts.
The prospect of your phone being able to see through some objects is a terrifying one. In the OnePlus 8 Pro's case, that is limited only to materials without IR shielding. XDA Developers' Mishaal Rahaman and a Reddit user were also able to reproduce the effect with other objects. Any source of infrared radiation is susceptible to the lens' ability to detect IR waves. When everything is said and done, this is little more than a parlor trick OnePlus 8 Pro owners can use to impress their friends.
