This video shows you how to easily access the hidden Motorola Droid menu and how to improve call quality. The first thing you have to do is dial and call: ##7764726 . Then, type in the SPC Password, which usually is 000000 (six 0s) and hit OK. Next, click 04.Vocode in the popped up menu and choose either EVRC or EVRC-B for the highest call quality. Tap apply. Please note that better call quality requires more battery, so the battery will go down easier. That's it! Good Luck!
