How Do I Place My SGH-x497 In Silent / Vibrate Mode?
To place the SGH-x497 phone in silent mode hold down the pound key (#) for about 2 seconds. To exit silent mode perform the same action while in silent mode. You will see a confirmation message each time you enter or exit silent mode.
You can also place the x497 into silent mode by pressing and holding the bottom volume key on the side of the phone.
Carrying your phone in your pocket or purse may cause the phone to be accidentally placed into silent mode if the external button experiences enough pressure.
Unfortunately there is no way to disable or lock the external volume key.
