I'm having the same problem with dismissing an alarm in the lock screen. I can only snooze it. Same problem with answering a call and this started after an update a couple of weeks ago. DRIVING ME INSANE!!
Same, I am not able to dismiss my alarm or decline phone calls. Very irritating. The only way to turn off my alarm is to hit the side button which actually snoozes it, which I don't do (never snooze) or go into the actual clock app and turn off the alarm, which is counterproductive as I have a daily alarm set that goes off at the same time every single day which I now have to turn off and back on every single day making that functionality pointless.
I am having the exact same issue. Quite annoying to have to unlock phone, go into clock app, turn off alarm, then turn back on again for tomorrow. First world problem? Maybe, but annoying nonetheless. The title of this thread shouldn't say "Solved", since it clearly isnt.
This problem is not solved. I started using my Samsung S10 yesterday and first alarm clock this morning was impossible to dismiss despite the dismiss button displayed on the screen. Snoozing was the only option. Very frustrating. Please advise on how to fix the problem.
HOW did you try to use the dismiss button? Did you just touch it? I think you have to touch and hold and then swipe up to activate the button. Don't know why? Seems counterintuitive. Let me know if that helps.
