People have been complaining about the voice quality on their HTC Evo 3D being less than perfect. These instructions will show you how to improve this so that people on the other end don’t think your hanging out in a tunnel.
What this will do is change the vocoder that your phone uses (this is the technology that encodes your voice on a call). This is not permanent and can be switched back if needed. In most cases you will never want to go back and we have seen the voice quality on EVO 3D’s be so bad that people put the phone down and borrow one.
Instructions to Improve Voice Quality on the Evo 3D:
- Go to phone app and Dial ##3282#
- Choose Edit Mode
- Enter MSL (Ask technical support nicely)
- Advanced
- Change EVRC-B to enable
- Change Home Orig and Roam Orig to EVRC-B
- Hit Menu and Commit Changes
Again changes are not permanent and can be switched back if you run into and problems. This being said this setting does prevent Airave (Sprint’s Access Point Cell Phone Signal Booster) use based on users reviews.
We aren’t sure if there are any downsides to doing this since everyone seems to be happier after fixing the call quality using this method. I will ask that anyone using this little trick let us know your experience so that others know what to expect. Also if you are having any issues after trying this method we would like to hear those even more so that we can let people know the benefit/risk of this.
