Your phone makes a convenient alarm clock, especially since you can create multiple alarms for different situations and days of the week. But there are times when you no longer want all those alarms — perhaps you want to cancel an alarm before it goes off, or delete it entirely.
How to cancel or delete an alarm on Android
How you cancel the alarm on your Android phone depends on when you want to cancel it.
- If the alarm is already going off, tap Stop at the bottom of the alarm screen.
- If you tapped Snooze and want to cancel it before the next alarm cycle goes around, start the Clock app and find the alarm that’s still in progress. Tap Snoozing until [the time the snooze will sound again]. This will dismiss the alarm until it’s scheduled to go off again.
If it’s snoozing, tap the Snoozing message to cancel the alarm.
