I agree with Papbot’s post above. “Your friends” (or you, in this case) shouldn’t bring the device to the Apple Service because that’s not a failure during the usage of the device, but a faulty piece from the factory. You’re on your right, during the first 14 days, to exchange the entire device for a completely new one. And, in my opinion, you should ask for a replacement in brand new condition.
Why? You may ask. Well, if you go the Apple Service route, you’re basically trapped with that machine. If the screen replacement is faulty as well, if the new screen has a different quality (happened to me with my Unibody MacBookPro, the replacement screen had much worse colors), you cannot say “okay, I’ll return it and get an iPad mini, or an M2 MacBook Pro, or a Dell XPS with that money “. You’re basically trapped with a faulty, expensive machine. Sure, you have 1 year of Apple Care but who knows how many times they will agree there’s a problem with that machine. The Geniouses are expert in gaslighting you when there’s not a flagrant problem with the machine, especially since Steve Jobs stepped down. “I don’t see anything, maybe it’s in your eyes “, “the battery is running as it should, our test says it’s healthy “, “maybe that third party app that you installed is causing the issues”, etc.
So I would be cautious replacing the screen, performing a repair, on what it should be a brand new device like yours. If you’re in the first 14 days, you have the right to demand a new one as a replacement. And judge by yourself if that new one meets your quality standards. This is not an Acer computer, or even an HP. This should be the Lexus of the laptops.
Good luck! Let us know, not only if you can get a new one (this is likely even if it’s because you changed your mind), but more importantly, if they acknowledge there’s a technical issue.
