I don’t know about you, but I really don’t like it when my Android smartphone confirms every click with a tone. And I certainly don’t need it to beep when I dial a number.
If you’re annoyed by the constant beeping tones on your Android device, here’s how to disable it.
In the main menu, click Settings. Then tap on Sound.
Now, scroll all the way down the menu and uncheck Keytones and Touch Sounds under System.
The settings above will be named something different on other versions of Android and devices. Navigate through the menus, and uncheck the option to turn off Touch Tones.
