OMG thank you so much, this finally worked!. I tried everything suggested on the previous twenty responses, this is the only thing that worked for me, no more missing alarms!
Others here (especially SRFOOT) have been helpful in posting solutions. I combined what several people have suggested
into these instructions which I hope are clear:
Open (slide down) notification bar.
Click on top right icon to open icon page. Click on pencil icon to edit buttons. From available buttons (icons), drag "always interrupt" button (the icon is a star) to the top section with the other active buttons (icons). I put this button next to the sound button.)
When the button is off (meaning it's dark), it will say "Always Interrupt." That is the normal mode that means your phone will act the way a phone is supposed to act.
When the button is on (meaning that it's lit up), it will say "Priority Only." When it's in this mode, do NOT put the phone in mute. Leave the speakers on. The effect will be that the speakers are on, but only priority notifications will get through.
If you get a phone call, the screen will light up, but the ringer won't ring.
Now go to Settings/Sounds and Notifications. Scroll down to Application Notifications. Scroll down to Clock. Turn Priority to ON. Do the same for any other apps whose notifications you want to make noise when the phone is in Priority Only mode.
How to use this:
When going about your daily activities:
- Sound icon is set to SOUND.
- The star icon is set to ALWAYS INTERRUPT.
- The phone is not in AIRPLANE MODE.
When in a movie theater:
- Sound icon is set to MUTE. That means that NO notifications will get through.
When going to bed:
- Sound icon set to SOUND. (Yes, this is counterintuitive.)
- Star icon set to PRIORITY ONLY. (That will make the sound icon change to SOUND/PRIORITY.)
- Phone in airplane mode.
IF you have the clock app set to priority, it should wake you up tomorrow morning, but your beauty sleep should not be bothered by any other notifications.
I hope this is helpful.
