HD Voice is a cool option which changes the frequency and bandwidth of phone calls. It is quite an awesome feature as it provides better audio quality and deeper clarity. So, talking to your friends and your family will be a better experience because the sound coming from the person you are talking to will be clearer and it will be more enjoyable overall.

The Samsung Galaxy S4 supports this option even though it is not enabled by default. However, you can activate it right now because it is an easy and quick process.

    • Hello Thomas, once you type the value “1” and select ok, you should wait a few seconds until a Menu Page will appear. Then, click the Menu button and press Back. Then you will be able to choose those values. Try it again this way and see if it works.

    My rooted S4 on 5.0.1 Toucheiz won’t let me go to the 7 thing

    I have tried both dialing *#0011# and as poon64 suggests, *#197328640# on my S4 and get the message from Verizon that “there is no such number” when I press the green handset “go/dial” button. What am I doing wrong?
