The Samsung Admire does not have an LED notification light. What looks like an LED light (to the left of the earpiece) is actually a light sensor for the display to auto-dimm (if you have this feature turned on). The Samsung Admire has no LED's in it at all.
Samsung vitality does not have a notification light. That feature is not there. Though many people think that the sensor next to the earpiece is the notification light, it is not and cannot work in the same way as a notification light sensor.
