I dont have this problem. I actually like that there's virtually no delay when using the buttons to take a screen shot. It makes the phone sluggish and also is annoying to have to deal with a delay for the edit options to pop up. I like things to be swift and accessible. Samsung should release an option to disable it if its getting in the way for some users.
Please post a solution if one exists . I don't see a setting I can disable for this so called smart capture for the Cricket Galaxy S10. Maybe it exists for the non branded version. It's very annoying, up there along with the unreliable fingerprint reader that made me miss my S9.
