I don't know what happened to it, but I updated my software last week. This morning, I checked my phone there is a vertical green line at the center, and I felt shocked, worried, and sad at the same time. I just want to know what happened to my phone. My screen is in perfect condition; it has never been cracked or smashed.
Ouch. I suppose you explained your situation? Search in the community for those with green lines. IIRC there's a reputable Samsung service center that assesses better than others.
