There's some bad news for your nudes. According to a number of user reports, some Samsung devices are randomly sending out images to their contacts via MMS. The complaints come from both the official Samsung community and from Reddit.
In the latter, the user claims that their entire photo gallery was sent to their girlfriend, and there's no record of it at all in the Messages app. The issue does seem to be present in the Samsung Messages app, which is obviously the default SMS client on Galaxy devices. Users are only finding out that the images have been sent from responses to them.
First spotted by Gizmodo, Samsung issued the following statement:
We are aware of the reports regarding this matter and our technical teams are looking into it. Concerned customers are encouraged to contact us directly at 1-800-SAMSUNG.
No one really knows why this is happening, but some are suggesting that it might have to do with carriers' recent implementation of Rich Communication Services.
Luckily, there are a couple of solutions that you can try. The obvious one is to switch to a different texting app, like Android Messages. According to Gizmodo, you won't be affected anymore if you do this. The other - which you'll probably want to do even if you change your default SMS client - is that you can go into your Settings and turn off Samsung Messages' access to the phone's storage.
