How To Solve Samsung Galaxy S3 Flashing Notification Lights Problems

If you hold your Samsung Galaxy S3 facing to you, you will see a L.E.D at the left side of the earpiece. The L.E.D is used for notifications so that the users of this phone can understand when messages come in, the Galaxy S3 needs to charge or if they have missed any call, without touching or unlocking the screen. There are three colors of notification lights such as red, blue, green and three rhythms such as blink, pulse, and glow. So it is easy to remember their meaning.

Pulsating and blinking are not same. Pulsating means the LED is little shorter or longer and then it is off and creates a noticeable rhythm. On the other hand, blinking means a steady turning on and off of the light.
