Given the Nokia 6 has no notification LEDs but does have capacitive button backlights(back and minimize buttons)there is a possible notification solution(like in nokia C5-06).Custom ROMs have long made notifications via blinking the capacitive button backlights (aka BLN) available. For me this would be a welcome addition to an otherwise accomplished phone. PS not necessarily wanting to run custom ROMs on this phone especially if Nokia continue to make good on their promise of fast updates. So addition of BLN as a stock feature is the aim here.
This is a great suggestion. It blows my mind that some versions of the Nokia 6 have a notification LED and others do not. What possible reason could Nokia have for committing this stupidity? Anyway, adding this functionality to one of the button backlights would help make up for this bewildering deficit.
