How Do I Disable Or Change The Startup / Shutdown Tones On My SPH-A460?
There is not a way to turn off the sound when the phone is powered on and off. You can attempt to turn the volume down to the lowest or to vibrate before powering on or off but there is no configurable option to turn the sound off at these two events.
To adjust the volume, simply press and hold the volume button which will toggle through the options available, select Vibrate or Off to silence this sound. However, this changes the sound for the entire handset, if set to Off, you will not hear the ringer for incoming calls.
