My one and really only gripe on my mate 9 is the dim LEDS and how it handles notifications. it seems sometimes it works and sometimes it don't. I am trying out an APP called LED Blinker Notifications Pro... you can also try the free version. works great. basically puts the led of your color right on the screen. customize it anyway you want.(color and size app and location) the only small negitive is it uses your screen. but even there you can dim it.....
