Samsung Knox warning message appears when your phone starts up
Knox is Samsung's security system and this message appears if your phone detects unofficial software or modifications. If you haven't rooted or modified your phone, swipe away the notification — it's just an alert. If the message persists, restart your phone and the warning will clear.
Samsung Knox is a built-in security system that monitors your phone for unauthorized modifications. Sometimes it triggers false alarms or shows messages when your phone legitimately has a custom ROM, an unofficial update, or a configuration change. The warning itself isn't a sign your phone is broken or hacked.

Skip, I just want a technicianCommon mistakes to avoid
- Panicking when you see the Knox warning and thinking your phone is hacked. Knox warnings are usually false alarms.
- Trying to disable Knox completely instead of just swiping away the notification. Knox is a security feature and should stay enabled.
- Ignoring a real Knox warning about your bootloader being unlocked if you actually rooted your phone.
Signs you need professional help
- If Knox shows a warning about bootloader being unlocked and you didn't intentionally unlock it, or if the warning persists after multiple restarts, get in touch — your phone may need a software repair.
