I love Samsung Galaxy S II Super AMOLED Plus screen. The black is really black. I always want to turn my phone into a LED night clock. Samsung Galaxy S2 can perform this task perfectly because I don’t see backlight in black colour like my other Android phone HTC HD2 which use normal LCD screen. However, it is not advisable to turn on AMOLED screen all the night because it will reduce its lifespan. Anyway, here is the top free Android night clock for Samsung Galaxy S2.
