[Android Central Question]

Hi. Why do I have two separate conversations with the same person in SMS Messages?

Which phone are you using? What messaging app? Does your contact have more than one number listed?

Welcome to Android Central! Is it possible that one of those threads is actually a group thread?

Welcome to Android Central! Same question to you -- is it possible one of those threads is actually a group thread? Also, what about Kizzy Catwoman's questions?

What if you delete both threads and start a new conversation with that person?
