Frequently Asked Questions
Can I see notifications I dismissed before turning this on?
No β notification history only starts collecting from the moment you turn the feature on, so notifications dismissed earlier can't be recovered retroactively.
Does sensitive content stay visible in the history too?
Yes β whatever text appeared in the original notification is stored as-is, so if you share the device with someone else, it's worth also checking your lock screen security settings.
