I updated to the beta version and within a week my phone got a pink line across the screen.
It was spontaneous, i was watching YouTube and suddenly i noticed a very dim pink line, i restarted the phone and it disappeared. Within 10 mins the line returned at the same spot and this time it was more brighter and since then it has not disappeared.
Will be visiting a samsung service centre soon, will update what options they give me there.
And also be careful regarding beta updates
