Yes, the mighty Android phone ~ Samsung Galaxy S II does not have LED notification light just like iPhone 4. If Samsung Galaxy S2 is your first smartphone, you might not have any issue. Just press Home button, and you can see any missed call or SMS on the lock screen. But for users like me who coming from HTC HD2 with LED notification light, you might need to take some time to adapt to it. Or make your own LED notification light for Samsung Galaxy S2 by installing NoLED.
