What can i do about a purple splotch in the corner of my screen.

[Android Central Question]

I have a galaxy A7 2017. I recently replaced the screen after I cracked the last one, but now there's a neon purple stain on the top right corner that's only visible when the screen is a pale color. I've heard other people say this happened to them, and that their stain grew until it covered the whole screen. Is there any way to fix this? Thanks!

Only by replacing the screen.
