Set an Alarm auf Samsung
The Clock app on Samsung phones keeps one default alarm active by default, which is why many people never notice they can add more. Every extra alarm you create runs independently: it keeps its own time, days of the week, name, tone, vibration and reminder setting, so you can build a whole schedule without touching the default one.
To add a new alarm, open the Clock app and follow this path:
Tap on Clock ➔ Tap on Add ➔ Set the Alarm time ➔ Enter an Alarm name ➔ Set Other options ➔ Tap on Save
The name field is useful once you have several alarms running, since it lets you tell a work alarm apart from a weekend one at a glance. Under Other options you choose repeat days, snooze behavior, alarm tone and whether the phone should vibrate alongside the sound.
Once saved, the new alarm appears in the list alongside your existing ones and switches on automatically. If an alarm does not ring at the expected time, check that it is toggled on in the list and that the device is not in a mode that silences notifications, since that can affect alarm behavior separately from the alarm settings themselves.
