HTC One X: Repeating\duplicate text messages
Chris Glahn... worked for my HTC One X. thanks! I went into Settings>Application Settings and cleared cache on the messaging, and the Google hangouts' apps. Then I went into ALL and found running services for messaging, hangouts ... basically all the services running and stopped each one, leaving only my keyboard and services apps - the only two that didn't have options to close. After all services were stopped, I restarted the phone. Repeats stopped. Discuss this with your techs.
