Some iPhone X/8/8 Plus users are complaining that the alarm clock not working, that means, the alarm not sounding or ringing after update to iOS 12/11.4/11. In this guide we will summarize the possible solutions to Alarm not working on iPhone X/8/8 Plus. But if you own an iPhone 6/6s/5 or iPad, these tips are also applicable. Let's get started.

Suppose your iPhone X alarm won't sound or ring at random, you'll need to check whether you have set the alarm for one day only or for every day.

To check Alarm settings, please open Clock app > Alarm, tap on Edit and then choose an existing alarm, or click "+" to add a new alarm, in "Repeat" option, you can choose the repetition.
2. Check Volume Level and Mute Button
This is important, you need to turn off Mute and adjust the sound volume loud enough to wake you up.
3. Check Alarm Sound
Also, please make sure you have selected one ringtone as alarm sound. If you set the alarm tone to "None", your iPhone alarm does not ring definitely.
Go to Clock app > Alarm, select Edit an alarm, and you'll see the Sound option. In the sound option, you can either pick a song or select a ringtone as your alarm type.
