One video even said the user discovered the reception issue with his Droid Incredible after calling 9-1-1 about a break in. He had to switch to another phone to complete the call and get help.
There are plenty more videos like this on YouTube. You can even try it out with your own phone. I had problems talking with an AT&T rep today on my Glyde, until I held the phone only with my fingertips. Only then was I able to understand enough to talk with the representative.
As a reminder, Apple had around half a percent of iPhone 4 users mentioning a reception issue. Compared to these tests, and the Droid X’s faulty screen, it’s hardly an issue.
