I’m very happy the notification LED is finally working on the Fairphone 3. Nevertheless I’m still annoyed by the fact it doesn’t produce clean colors.
The built-in hardware consists of a red, a green and a blue LED, all others colors a mixture of several of them lighting up at the same time. For some reason there’s a delay and not all of them light up (and go dark again) at the same time (or being equally bright to produce the correct mixture), so the resulting color changes over the duration of the light pulse.
White: Off -> Red -> White -> Green -> Off Magenta: Off -> Red -> Magenta -> Blue -> Off Yellow: Off -> Red -> Yellow -> Green -> Off
This might sound purely cosmetic but since the chosen color is just visible at the peak of the light pulse I’m asking myself whether there’s room for improvements or if this is a technical restriction they had to deal with (it took some time to get the LED working it all, there might be technical hurdles we don’t know of).
Between the light pulses the LED doesn’t turn off completely - it keeps being a little little bit brighter than the surrounding area, thus visible in a dark room.
