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.

This is an absolutely inappropriate solution. it's a year later and i'm STILL having problems - and now with iOS 11, MORE problems - with the alarm feature. i use my phone for, in priority order:


1. calls

2. texts

3. alarm

4. pics and internet


ALARM..


as in - i missed a flight sunday, which cost me $75 (i was lucky) to change my flights after the fact. i have been late to work this week. no - buying a 3rd-party software so i can reset my phone to factory settings without losing my data is NOT an appropriate response. I am an app tester for a living - there is absolutely no reason why this shouldn't have been fixed long ago except for tonedeafness of the product team. if the basic apps aren't reliable in something so necessary, the phone isn't worth it.

Same thing happened to my iPhone 6S Plus and now 7 Plus, in the last couple of months. Everything started after updating the iOS to version 10 and none of its versions seems to be fixing the problem. I even tried am older 6 Plus for a few days and ran into the same problem with iOS 10. I tried everything recommended on this thread and some more, to no avail. After each fix, the phone works for a couple of days (more or less) and then suddenly the alarm won't go off in the morning, without any reason. I couldn't find any specific pattern in the phone's usage that triggers this nasty iOS 10 bug, it seems to be completely random so far.


Apple, please address and fix this iOS 10.x.x problem ASAP!!! There are so many of us impacted by it!
