What snooze does
Snooze temporarily dismisses a notification and brings it back after a set time — usually 15 minutes, 30 minutes, 1 hour, or 2 hours. It is Android's built-in "remind me later" for a single alert.
Where the snooze button is
Slowly swipe the notification to the side (but not all the way off), or press and hold it, and a small clock or snooze icon appears. Tap it, pick a time, and the alert disappears until then.
How long it waits
The default options are 15 minutes, 30 minutes, 1 hour, and 2 hours. Some phones and launchers let you change the snooze length in notification settings.
Snooze vs. dismiss
Dismiss deletes the notification for good. Snooze hides it and resurfaces it later. If you just need a nudge in half an hour, snooze. If you are done with it, dismiss.
When pinning works better
Snooze brings the alert back on its own timer. If you want it to stay put until you act, Dingpin lets you pin the notification at the top of the shade — no timer, no surprise reappearance.
