First of all, wake up your device, and reach the home screen. Every Android phone has a dedicated key for the main menu. Just tap the button and go inside. After entering the main menu, you will see plenty of icons. Focus only on the icon of Settings. Click on it, as you find it. It will take you straight to the System Settings.
Another way of going to the System Settings is to push the ‘Options’ button, while staying on the home side. A list will pop up, and you need to pick Settings/System Settings out of it. The main objective is to reach the Settings, no matter which way you choose.
Having entered the System Settings, focus on the Sound Settings, which you will find right under the heading that says ‘Device’. Other options under this heading are Display, Storage, Battery and Apps. Tap the ‘Sound’, and go inside.
A long list of options will appear on your screen. Scroll down, and look for the option that says ‘Touch Sounds’. Don’t lose your patience, as it is there somewhere in the list, lying right under the heading of System.
There will be a small box right in front of the text. Uncheck the box, and the mobile will turn off ‘Touch Sounds’ immediately. Make sure that the blue check mark has disappeared from the box. Your touch sounds have been turned off now.
