Have you recently gotten your hands on the brand new HTC EVO 3D? If you have, are you one of the users who have been experiencing poor voice quality during phone calls? If you are, it looks like there is a solution for you, and it involves nothing more than entering your phone’s edit mode and following a simple set of instructions. It seems that users who have tried this experienced a vast improvement in their call quality, so if you’re affected by poor voice quality, perhaps you should check out the thread here on the AndroidForums.
We can’t guarantee if it will work, so all of this is done at your own risk, but to be fair it does look pretty simple, and based on the forum comments, it is not permanent and you can choose to revert the settings later if it does not work out for you. However, if it works out, we’d love to hear from you!
