How do I turn off the keypad tones on my Samsung Tocco Lite (GT-S5230)?
You can adjust the key tone volume by pressing the Volume key or in idle mode. The Volume key is located on the upper left side of the phone.
The volume settings range from level 1 to level 7, where 7 is the loudest and 1 is the lowest.
NOTE: You can also adjust the intensity of the vibration by pressing or in idle mode. Select Vibration by tapping the screen and adjust the intensity of the vibration.
