How to Change a Voice Codec on a Droid

The voice codec option is hidden in the programming menu.

The Motorola Droid smartphone uses the EVRC voice codec by default. Droid phones also include support for the older 13K voice codec and the newer EVRC-B voice codec. You can change the voice codec your Droid uses from its hidden programming menu. EVRC-B may improve your call quality, although it could potentially decrease your phone’s battery life. You can experiment with the different voice codecs and test them on your cellular service provider’s network.

Instructions

1. Tap the “Phone” icon on the Droid’s home screen to open the dial pad.

2. Enter “##PROGRAM”, or “##7764726”, on the dial pad and tap “Send.” A password dialog appears.

3. Type “000000” into the password dialog and tap “Verify.”

4. Tap “Test Mode” on the programming menu.

5. Tap “Next” twice.

6. Tap “13K,” “EVRC” or “EVRC-B” under Service Option, and exit the programming menu.

Tips & Warnings

• The programming menu contains a variety of options that are hidden from average users. Don’t change options in the programming menu unless you know what you’re doing.
