Left side of Air 2 screen is brighter than the rest
I have an iPad Air 2 that is almost 2 years old and since a few months ago, I’ve noticed that the left side of the screen, if you hold it with the button on the bottom, is noticeably brighter than the rest of the screen, it’s like 1 centimeter (half a inch) band, and it’s gradual: the screen side is brighter and it becomes normal gradually to about 1cm into the screen.
It doesn’t look like burnt screen (it shows no pattern, no colouration…) and I don’t know if the side is brighter or if the rest of the screen is fainter. I don’t know neither if the problem will get worse or if it will keep as is now.
Is it a known issue? In Europe, iPad has a two-year warranty so if it’s a know issue, I should to to an Apple center to have it fixed.
