When you move finder to UBorder, IsHovered sets to true. But when you lift your finger directly IsHovered doen’t return to false. I think it is a bug for mobile?
Hey
You can’t hover over a touchscreen therefore, hovering over it will not cause it to properly function. If you’d like to make buttons that are pressed, you may want to use a touch event instead of the ‘is hovered’ function. However, I have entered a report in based on how this function is actually working on mobile devices. If you’d like to check on this report in the future, please reference: UE-20375.
If you have any further questions, please let us know. Have a wonderful day!
