Dismiss alarm clock/Answering a call by Pressing Not Swiping Fixed!!!!!!
I just purchased a new Galaxy S10+ and was very frustrated that I could not dismiss the alarm clock by simply pressing the dismiss button when the alarm rang. Also the same with answering a call by pressing the green phone button. I had to swipe both instead. Very annoying. I called customer support twice but they told me I had to swipe both. Well, a little investigating and this is how I fixed it.
