I purchased a Galaxy S6 last night, and it might be sending duplicate text messages. I'm not 100% sure if it's my phone because so far only one person has mentioned it. My friend, who has some version of the iPhone 5, said he's received at least 6-7 duplicate texts from me today. I tried both the Samsung Messages app and Verizon Message +. I couldn't find anything searching the problem, so I was wondering if there were any known fixes or anything, or if I have to go down to the Verizon store for a replacement (assuming the S6 is indeed sending double messages). I've also tried deleting the conversation history, which was a recommended fix for other phones, and it doesn't seem to have helped.
