Black area at the bottom left of the screen
Couple of hours ago I found out there is a tiny black spot at the bottom left corner of my screen. It doesn't look like dead pixels (or maybe it is, I dont know) but when the screen is white I almost don't see it. But when the backlight is grey, purple or darker colors I can clearly see it And it's making me really angry because I paid so much money on it. First I thought it's because of the screen protector, so I removed it. But the little shadow is still there. Please share your thoughts. Anything helps.
