My alarm clock does not ring, Huawei P smart?

I have recently a Huawei P smart (was previously an Apple user). The last 3 days my alarm has never rung. Yesterday I set my alarm clock with "ok Google". It was then your alarm clock rings in 10 hours. I woke up about 10 to 10 today and then I waited. 10:00 Nothing, no alarm, no vibration, not once the alarm clock was displayed. Also in the alarm settings the alarm clock was switched off. What can be there?

I have a Samsung and have the function "Do not disturb!". Look if you have such a function. Because you can set so that really nothing rings (no alarm clock) or even so that nothing rings except the alarm clock…

Otherwise, just try it with a newly created alarm clock. Alarm time to +2 minutes and just watch that an alarm sound is defined and activated and the vibration as well. Just watch that the alarm volume is loud enough.

That's the weird thing, set the alarm to 10:10 earlier:

Super loud, super annoying, everyone will wake up

So does this alarm clock work? Then take this one now and put it on tonight at 6 pm or so and see if it is so annoying again. If so, put that on the time in which you want to be woken up…
