I just tested this again to confirm. Set timer to 45 seconds. It paused my bluetooth music (earbuds) and the alarm sounded through the phone speaker. I could barely hear the muffled alarm. Only because I was listening for it. The paused music was noticeable because I was awake.
I missed a appointment a few weeks ago. My alarm was set for 11 AM. I fell asleep around 9:30 AM listening to soft music. I never heard the alarm.
I expected to hear the alarm through the ear buds
Why would bluetooth fail to use that audio source?
It’s probably under the control of the alarm app itself. The stock alarm on my Galaxy Note 9 will play the alarm through both bluetooth (if I’m using my earbuds at the time) and the phone speaker. In your case I would try installing a few different free and ad-free alarm clocks available on the Play store and test them.
I had a alarm app that played music. You could pick any song on the device. Worked great. Then a update to Android 4 broke the App. I checked other clock Apps and they were broke too. Sometimes tbe alarm didn’t go off. I needed a dependable alarm.
I’ve stuck with the stock clock App since then. Samsung has their own Clock.
They should have fixed it by now. I’m running Android 11 now.
Then the one you might want to try from the Play Store is just the regular Google Clock app. I use it, and it always plays the alarm in both Bluetooth and from the device.
That said, as much customization that Samsung has, there may be a setting in either the alarm app or the phone’s settings that determines if an alarm plays over Bluetooth. In the phone settings, I’d suggest searching just Alarms and Bluetooth and seeing what you can find.
(Unfortunately, I don’t own a Samsung phone, so I can’t give more tailored advice.)
I use one called AMdroid and I just verified it will play the alarm through my bluetooth ear buds. I don’t know if that’s something I set someplace, or if it’s the default condition.
In many ways the app is confusing and annoying to use, but it does a great job of making me do arithmetic problems which are just hard enough to wake me up adequately before turning off the alarm.
I use the default Samsung Clock, it plays through both bluetooth and the phone itself simultaneously. Almost kind of annoying when I’m going for a walk or something and the phone itself isn’t silent, but whatever. It’s pretty basic, I realize I should look into a new one to try. Keep recommendations coming please!
