I am disappointed that many phones/tablets don't go very dim.
From flagship to cheap, it seems that if you're in a pitch black room and check the time on your phone, the light will illuminate the whole room, even on the dimmest setting.
I actually modded my phone by putting a resistor in the LED backlight circuit, which divided the brightness by 1000 - and it was still plenty bright at night (human eyes are logarithmic, so dividing the brightness by 1000 doesn't have as much visual impact as you'd expect).
