Not sure if they can fix s20 screens. Since they sell them, they may be able to recommend a place that does.
You will want to call ahead and make an appointment....I was there a week ago and as you walk in they check you in of what you need to look at it or do.
Im sure they can, but i would go somewhere where that's all they do.
I don't know I've never really needed to fix screens on my phone's
