This really helped me

I've tried it and it works for me... no more pink line.
this didn't work on my S7 Edge. I have a used phone and the previous owner said there was a pink line and I tried this app called Pixel Fixer but it didn't work or the *#0*# and it did nothing.
Would Samsung take the authority to fix this problem as the same myself n mine frnd is going through the same issue with our S7 edge
