I’m glad I saw this thread. I also got hit with this exact issue. I have the iPad Pro 12.9” 2nd Gen bought 1 year and 9 months ago. It started with one spot in the top corner about 3-ish months ago and has spread to 4 or 5 other spots. Always the top left corner, and always along the side that connects with the Smart Keyboard. I always have my iPad in the case and take very good care of my electronics.
I first called Apple Support on the phone and spoke with someone who recommended I take it into the store. Of course COVID-19 put a damper on that for about a month. Finally I was able to get a spot on the schedule. The tech ran diagnostics and concluded that it was not caused by the user, but they could not admit it was a manufacturing defect. The only two options I was given at that time was; send it in to be serviced which means it would more than likely be replaced with the exact same model and I would have to pay $650, or option 2, buy a brand new iPad and trade this one in for $270.
I was bummed. I did some searching and found this thread, then I spoke with two more people through Apple chat support. The first guy was not helpful at all. Kind of a jerk actually. The second guy actually listened, but still recommended I take it back into the store and speak to a manager. I told him I didn’t want to be that guy. He said, ‘no really, this is what you need to do.‘ My local store was booked solid so I had to drive more than an hour to another Apple Store. I spoke with a tech and then a manager.
Bottomline, Apple doesn’t recognize this as a manufacturing defect. I refused to swap this out with the exact same model based on what I read here because I would have the same issue in another 1.5-ish years.
I bought a brand new iPad Pro and am trading this one in. Everyone I spoke to in-person said they would honor the $270 credit. We’ll see if that happens. I’m still not happy about this whole situation.
