If you’re reading this, it’s possible you were late for something important. iOS 11 has an alarm bug. It hasn’t been acknowledged officially but a lot of people in lots of forums are complaining about missed alarms. Normally, you can attribute a missed alarm to having overslept but if it happens one too many times, you start wondering if it’s you or your alarm clock i.e. your iPhone. The alarm not ringing bug has been reported on devices running iOS 11 – iOS 11.1. Here are a few fixes.
Fix Alarm Not Ringing
Try all these fixes instead of just trying one and expecting it to fix the problem.
Update iOS To 11.2
iOS 11.2 is out and it has quite a few bug fixes. The alarm not ringing on iOS 11 isn’t listed but it’s possible that with all the other iOS 11 bugs Apple just didn’t want to mention it and fixed it under the hood. This means that the update might or might not fix the problem. Regardless, update anyway and then follow the other solutions below.
We normally never restart our devices but it seems to be one of the things that appear to fix the problem according to users that are experiencing it. Shut down your phone and turn it on again.
Delete Alarm And Add A New One
This will take a bit of time but delete all the alarms you’ve set on your iPhone and add them again. To delete an alarm, open the Clock app and go to the Alarms tab. Tap edit at the top left and then tap the minus button next to each alarm to remove it. Tap the plus button at the top right to add a new alarm.
Change The Alarm Sound
Change your alarm sound to something else. If you’re actually sleeping through your alarm, this ought to fix that as well. More importantly, if a particular sound file is corrupt or the OS can’t ‘see’ it, this might fix the problem. It doesn’t sound plausible but iOS does have bugs like this. One infamous, still unacknowledged bug is the photos not appearing in camera roll bug.
To change the alarm sound, open the Clock app and go to the Alarm tab. Tap the edit button at the top left and then tap the alarm you want to change the sound for. On the alarm edit screen, tap sound and select a different sound for the alarm.
Delete Alarm Apps
If you have any alarm apps or apps that claim to help you sleep better, remove them from your phone. If there’s data that you don’t want to lose, check if the app has a back-up option. If the app doesn’t have a back-up option for the data, offload the app instead of uninstalling it.
Alarm Not Ringing – Bug
This bug manifests in different ways. For some users, no alarms are ringing. For others, the alarms ring on some days, but don’t on others. In other cases, only one or two particular alarms fail to ring, and they do so at random i.e. sometimes the alarm will ring and other times it will not. This is what makes it hard to pin-point whether it’s you that’s sleeping through the alarm or the alarm that’s not ringing.
