If you are getting an odd look out of a co-worker or a friend then they may have gotten a message from you that you didn’t send.
A few Samsung customers are noticing random messages being sent that included their photo gallery. So if you are using Samsung’s messaging app look to see if any messages went out that you may not have sent.
According to reports, the issue has been isolated to customers on T-mobile using the Samsung messaging app. And this could be a result in a bug following the recent RCS messaging update, according to Engadget.
