Often we misplace our phone. If you muted the ring, then you can't even call from another phone to locate it.
That's when Android Device Manager comes in handy. Go to google.com/android/devicemanager The site will automatically connect to your phone and display a message like: "Last located at 6:42 PM; Manekshaw Parade Grounds Bus Stop, Cubbon Road, Shivaji Nagar, Bangalore, Karnataka 560001, India - Accurate to 574 meters. Last used August 14, 2013".
To locate the device, click on Ring. The device will ring at full volume for 5 minutes. You have to press the power button to stop it ringing.
