How to find dismissed notifications on Android

Open Settings → Notifications → Notification history. With Use notification history on, Pixel keeps a list of dismissed alerts from the last 24 hours. You can also swipe down to open your current notifications, scroll to the bottom and tap History when it appears. Tap a history entry to open the app that sent it.

Open Settings → Notifications → Advanced settings → Notification history. Look for the app in the list. If the switch is off, turn it on to record future alerts. An empty list after you enable it is expected until the phone receives new notifications.

Once history is on, send yourself a test message from an app that already delivers notifications. Swipe its alert away and look for that entry in history. If your phone has a different menu, search Settings for notification history. Some Android devices lack this feature.

If the alert is outside the history window or arrived before recording was enabled, open the app and check the relevant inbox, conversation or activity screen. A cleared calendar reminder, for example, may still have a corresponding event in your calendar.
