The problem appears to stem from Samsung Messages, as first reported by Gizmodo. What's even worse is that the app reportedly leaves no evidence of photos being sent, which means users won't know when their phone may have unwittingly sent sensitive photos to a friend or co-worker until some time has passed. Users only find out the photos have been sent when they're asked about it. Samsung has said it's now looking into the problem.
This doesn't seem to be an isolated case as some users have commented in the same post that they too have experienced the problem. Affected phones so far include at least the Galaxy Note 8 and Galaxy S9. "However, there was record of it on tmobile logs".
Users posted complaints on Reddit and Samsung's support forums about a unusual issue that appears to be silently sending photos to random contacts.
Another user added: "Oddly enough, my wife's phone did that last night, and mine did it the night before". I think it has something to do with the Samsung SMS app being updated from the Galaxy Store.
T-Mobile told The Verge that it was not an issue with its services and advised people checked with Samsung.
"This can be done by going to Settings - Apps - Samsung Messages - Permissions - Storage".
Samsung is now urging concerned customers to call its support lines directly.
Once you've done this, you'll no longer be able to open your conversations or compose new messages in the Samsung Messages app, as long as you continue to deny storage permissions. Notably, there's also no record that the photos were sent from an affected users' phone, according to the Reddit user.
