Since this morning I have been noticing a spot with pink and blue hue at the corner of my samsung galaxy A50. The phone was working fine yesterday and there was no physical damage and not even an incident where I could have dropped the phone in recent times. The spot is spreading very rapidly and it has already covered one fifth of the screen. Since the warranty has just very recently crossed, I may have to reach service center to repair my phone. I even started observing that green horizontal lines are appearing across the screen. If anyone has facing similar issue please advice and also let me know what caused this issue.
