You could try using a different texting app and/or revoking the Samsung Messages' app's photo permissions to be safe. The problem turned up on Reddit, spotted by Gizmodo, and then found its way to Samsung's official forums.
"Last night around 2.30am, my phone sent her my entire photo gallery over text but there was no record of it on my messages app".
Users who already updated may want to check carrier logs to see if their phone sent out images to random people, and they may also want to disable the app's ability to access the phone's storage so it won't be able to grab photos from the device anymore. The Samsung Messages app doesn't show any sign of sending the photos, meaning the user is completely unaware of the picture messaging.
Samsung and T-Mobile didn't immediately reply to CNET's requests for comment. He wrote that the app was sending scheduled messages early, that some messages were ending up in wrong threads.
Further complaints were posted to the Samsung Community page, all relating to a new protocol that rolled out earlier this year to Android devices to boost messaging capabilities.
There's a theory on Samsung's forums that this bug has something to do with the recent Rich Communication Services updates that carriers have been rolling out in the United States.
As you can probably imagine, many are concerned about this issue as having your photos sent to a random contact puts your privacy at risk. These features include improved media sharing, read receipts and typing indicators.
"We are aware of the reports regarding this matter and our technical teams are looking into it".
There are now two fixes if you are anxious about the issue affecting your device.
If you're using Samsung's Messages software, and are anxious about unapproved picture texts, find the application in the apps section of your device's settings, then go into its permissions, and disable access to storage.
