The Lumia 920 is something of a surprise success story for Nokia and the Windows Phone operating system, but an unexpected texting bug can cause some minor headaches if you don't know how to get past it.

One strategy more smartphone owners have started using lately is composing their text messages through voice, but an odd quirk in the Lumia 920's programming is triggering the phone to add an extra recipient when/if users edit their messages before sending.

The bug was uncovered by Todd at the Todd 4 Tech web site, and it seems only to affect messages that are edited after the voice command has been entered. If the phone recognizes everything you speak accurately and you send the message without editing it manually, then there appears to be no error.

As most smartphone owners know, however, voice recognition doesn't always work the way you want it to, and sometimes the phone just doesn't "get" what you're telling it. If that's the case, you'll probably want to add extra text, which you can do on the Lumia by tapping the pencil-shaped "Edit" button.

Once that button is tapped, though, the phone automatically adds a second recipient. This added entry is just the last name of the person you're trying to text, but since there's no phone number associated with the name, the message will crash and fail to send.

So while the bug doesn't cause sending private messages to random people in your contact list, it's still pretty annoying. Luckily, the issue is solved pretty easily.

First, go to the "Settings" option on your phone, click "Applications," then tap "People."

Look under the "Display names by" setting, and chances are you've opted to show contacts by last name first.

To fix the problem, simply change the setting so that contacts are displayed by first name, then last name, and the problem is solved!
