From my experience they will most likely return the device unfixed. They are hesitant to repair or exchange devices with "cosmetic defects".
Quite true. I’ve ordered computers and iPods from Apple directly and received them with physical damage right out of the box.
Called Apple like 5 minutes after signing for the delivery, and been told that since it doesn’t affect the function of the device and it’s only cosmetic that it’s not returnable. That Apple doesn’t cover cosmetic damage under warranty. Even if it was damaged before they shipped it to me.
And by damaged, I mean a quarter inch chunk of the case missing due to apparent impact at the Apple manufacturer location.
I refuse to buy anything direct from Apple anymore. Their policy sucks. So if I buy an Apple product, I always buy from a 3rd party that isn’t owned by Apple. That way I have better options.
The stores I buy from have a 30 day, no questions asked return policy. And it doesn’t matter if it’s damaged or broken or doesn’t work, or if it’s perfectly fine. Sometimes they’ll ask just so they know if it isn’t worth putting back on the shelf. But the reason I give them could range from “I decided I don’t like the color” to “I dropped it and this chunk is missing and it doesn’t work anymore”.
With Apple, it’s a gamble. The first round of MacBook Pro computers had numerous assembly problems where the cases were separated and falling apart before the buyer received it. Until it got to class action level, Apple just said it was cosmetic and since it was damaged, it couldn’t be returned.
With your phone, it’s possible you’ll get your same phone back. And possibly a charge for their time to look at it. Can’t remember if that term is still in the warranty. It was at one point. But honestly, I haven’t read their warranty in years. But the paper it’s written on is worth more than the warranty unless you buy from a 3rd party. Don’t buy from Apple directly if you want the option of returning it for manufacturer defects.
