Fix the Voice Quality Issue On Evo 3D [Guide]


HTC Evo 3D has a lot of edge over its predecessor Evo 4G in the department of display, processing power and a bunch of other stuff. However a phone is still basically known as a “phone” which is by definition a device for making calls to other users. It’s a shame if an amazing smartphone running on Android Gingerbread and having an actual 3D display can’t even make a proper, good quality phone call. Sadly, that is  exactly the case with Evo 3D. There has been so many complaints about scratchy and slow voice and degraded voice quality that it eclipses the phone’s s other features in a way. Although many other good smartphones have suffered this same issue in the past (read iPhone), things are looking really bad on Evo 3D. But with the Android community growing by the minute, someone was bound to come up with a solution sooner or later, and that’s exactly what has happened.

“Android Forums” member wega1985 has unearthed a fix to improve the voice quality on Evo 3D. He suggests that you simply change your vocoder settings for a better sound experience on your device. If you are wondering how that could be done, well here’s how.

  1. If you already know what your device’s MSL is, skip this case. However, if that is not the case, call your service provider and request the MSL. If you have a problem getting it from the customer service, you can follow this guide to get it on your own.
  2. Go to your phone’s dialer and dial ##3282#. This will open up a menu for you. It is via this menu that all the tweaking needs to be done.
  3. Choose “Edit Mode” from among the provided options.
  4. Input your MSL in the Edit field.
  5. After entering, select Advanced Options.
  6. Scroll down the list until you reach “EVRC-B” option. Enable this option.
  7. Go to Home Orig and replace it with EVRC-B.
  8. Now change Roam Orig to EVRC-B too.
  9. Tap “Menu” and save changes.

This has worked for most users and even if it somehow doesn’t work for you, you can simply revert back to the original settings as there is no hard change required for the fix. To see if it worked, try receiving a call when there is poor reception.
