Hello and welcome, lets do this once again.
I'm envy, creator of some popular custom themes for Samsung here on xda,
we finally got a method to apply "custom" themes for S10/S10+ (basically all Samsung PIE phones.)
please read carefully given Instructions as there are several method to make the theme work.
NEW TOOL METHOD: S10 and all device method https://labs.xda-developers.com/store/app/project.vivid.custom.themes.univ
This method is for ALL Samsung phones with PIE firmware, ROOTED/NON-ROOTED.
The concept is to download the target base theme from the Theme Store (Samsung created FREE theme) and replace it's contents with custom theme edits.
-Download a theme apk from below, only one theme at a time.
-Download the tool and follow all requirements, Read carefully what the app tells you to do.
-If you want to change theme, apply default theme and delete the base theme from store and do the method once again with different theme apk.
still confused? VIDEO INSTRUCTIONS FOR NEW TOOL METHOD:
