As the title have mentioned, this has been happening only recently. Up to date, the phone is around 2 years plus. Taken good care of. Hardly had any falls nor water accidents (incl. spills). Anyone had ever faced this issue before? Took a screenshot of the picture but the screen seems okay from the screenshot. By now, I know it's the hardware's issue.

Yes it does seem like hardware issue, get the screen replaced maybe.

I was really afraid someone would say to do a hardware replacement How much would it cost tho for getting the screen replaced? And have anyone confronted LED issue as well, where it's not turning on? How much would that cost?
