Screen replacment

3rd pary repairs offer flex connector replacement

the solution is to replace your screen, but from what i had learnt even after replace it there's still a chance green/pink line will reappear in the future, so my advice replace the screen then sell it

or yes there's some 3rd party repair shop that offer flexible cable repair, but either way you should sell your device after fixing your issue

Use "Dead Pixel Fix" app. Can be downloaded in google playstore. Watch youtube video tutorial on how to use it. It fix the green line of my phone.
