Improve the Voice Quality on Your EVO 3D

[danDroid]

Here's a quick tip to improve the voice quality on your EVO 3D:

1. Go to phone app and Dial ##3282#
2. Choose Edit Mode
3. Enter MSL (ask technical support nicely)
4. Advanced
5. Change EVRC-B to enable
6. Change Home Orig and Roam Orig to EVRC-B
7. Hit Menu and Commit Changes

Changes are not permanent and can always be switched back if you run into issues.

It is confirmed that the EVRC-B vocoder is not compatible with either Airave if you make these changes, however, the 13K (older) vocoder should work fine if EVRC is really getting on your nerves and your bound to an Airave. Further reading on 13K, albeit on VZW.

Call quality and volume are terrible. I've activated the hearing aid mode which helped a little on volume, but the quality is unusable as a gps in my car. When I try your directions, the screen asks for a password. Do I have to create one and if so, where do I do that? thanks. Paul

In step 3 you need to ask tech support nicely for it. You need the msl as suggested.

got the password and did the change. It did help a bit, but I'm afraid the real problem is their choice of a poor quality speaker. I'm wondering if anyone does equipment mods or just software. Or, if there might be an even better fix? Thanks in advance.
