iOS 10 - Alarm stopped working

I've upgraded my iPhone 6 to iOS 10.0.1 and ever since the update, my alarm clock no longer works. I can set an alarm, the alarm clock icon shows up in the upper RH of the screen, but when it's time to alert, nothing happens. The phone does not turn on, it does not create any sound. I've tried everything I could think of and the suggestions online, but no luck.


Another odd behavior is that even after an alarm has past (with no reaction in the phone) the icon in the upper RH remains. I can delete all alarms, the alarm icon still is present on the screen.


I've tried the new Bedtime feature thinking it my by part of the problem, but it also does not work. However, it does have some impact; if I turn on the bedtime feature, the alarm clock icon on the upper RH of the screen will go away and any alarm (on the alarm screen) that was armed gets turned off. It's as if the two are mutually exclusive meaning you can either use Bedtime or traditional alarms, but not both. Does anyone know if this is the case?


I really doubt I'll use the Bedtime feature, it's a little odd and not terribly useful for a hectic life that isn't too predictable for going to bed each night. However, losing total functionality of the traditional alarm clock is a huge disappointment.


I've tried restarting the phone; the only thing that does is make the alarm clock icon disappear (if it was stuck on from a prior alarm). It does not restore the actual vibrate / audible function of an alarm that is set.


I also deleted my iHome clock app thinking the alarms from that app might somehow be competing with the native iOS alarm function, even though they both worked fine in iOS 9.

I had this problem upon updating to 10.0.2 - alarm did not ring, my phone only vibrated. No ring tones would sound as I selected different ring tones. As I looked into this further, I noticed my Airplay was still set to Apple TV, not to my iPhone 6s. So my alarm was ringing, just through Airplay and not through the phone. I switched Airplay back to iPhone 6s and my problem was resolved.

Hi, I had the same exact problem. Then yesterday I realized that the alarm went off just fine when my phone is not on "Do not disturb" mode. I change my "Do not disturb" schedule and now my alarm works just fine!

The only problem with that theory is that Do Not Disturb doesn't silence the alarm. Even if you have DND enabled, the built in alarm will sound.

I am having the same problem too. You received a ridiculous response from apple... I am not going to reset my phone and reload all of my apps because of their technical mistake. Apple needs to just provide a bug fix/update ASAP!

If the problem is some sort of issue with, for example, corruption in the installed software, a restore is what it will take. It's possible that, if you do that, in a short time, you could have everything working again. Waiting for the next version of iOS 10 (which is unlikely to solve your problem anyway) will take a lot longer. But, it is, of course, your call.


Best of luck.

I recently updated my iPhone 6 to the iOS 10.0.1 as well and had many of these issues with my alarm and my phone ringing. My alarms were set as per usual and my phone was off silent and should be ringing, but nothing was happening. I tried deleting my alarms and resetting them, but still they "went off" but no sound. Same with my ringers - I reset everything, turned my phone off and on again and still no ring.


Finally, I remembered that I recently set up my Sonos Home Sound System that operates through an app on my phone and through my wireless at home. Since I don't use my Sonos player all the time, I deleted the app off my phone and powered the speaker down and POOF! My alarm goes off, my ringer rings, and I'm able to watch videos on social media.


Apparently this had to with AirPlay and some settings that I had set to on my phone for the Sonos player. It was simpler for me to just delete the app and only use when necessary at home.


Hope this helps!
