       Just observed something cool on my phone (Pixel 8a): the camera flash LED apparently continued faintly glowing for several minutes after I'd stopped using it to see in the dark. I thought that perhaps power was leaking to it after I powered the phone down and saw it STILL glowing, but then I powered up and briefly toggled the flash, and noticed that the glowing was brighter and oranger thereafter. This is some kind of phosphorescent doping on the LED module that is pumped by the diode! I'm guessing the point is that it fluoresces in another part of the spectrum to add some warmth to the cold native flash color. Once charged up, it continues to emit for a while after the pump is switched off, like a glow-in-the-dark geegaw.I just think this kinda shit is super neat, especially when it catches me by surprise like this.

       @theodric My old Motorola X Style did that once too, and then never flashed that LED ever again.I did now know it had that LED in the earpiece part before that
