The famed and often-reliable leaker Ishan Agarwal has published new posts containing some intriguing claims with respect to the possibly-imminent Huawei P50 Pro. This smartphone is now slated to have a 4G/LTE-only variant with quad rear cameras, 3 of which are to have high-res sensors with different and occasionally quite surprising functions.

IR camera would be a cool new addition, though it's most likely just intended for extreme low light. Visible light is about 40% of all light, but with IR 50% of all light and UV 10% of all light, full spectrum would have +150% more light than ordinary monochrome, but even simple monochrome gains more light without Bayer.
We will see how far they wander with their tech, obviously farther though than most competition.
