This is true, I am with you, but this is really important. I have a friend who turned on the flashlight by mistake all night on a different type of phone, and the flashlight turned blue because the yellow layer melted, and the battery was also drained because of this annoying feature.
Imagine before you put your phone in your pocket, before the pocket sensor is activated your finger turned on the flashlight and walk all the way without noticing. This literally makes the yellow layer on the flashlight that makes the rays white melt because of the heat It will turn an opaque blue color that resembles ultraviolet rays.
