OnMouseEnter/Leave Mobile

Hey there! I’ve got a small problem, it seems simple enough but I can’t seem to find a solution.

I’ve got an email button made of a picture on my contact page and it has an OnMouseEnter/Leave event to change the picture to different one (essentially changing the color of the button)
but the problem is on mobile when I press the button and it takes me to the email application, when I then switch back the button has disappeared.

I’m guessing when I click on mobile it loads the MouseEnter but not the MouseLeave and ends on nothing there at all so I was just wondering if there were an easy solution to this problem or something I’m over looking? Thanks!
