Not to diminish what any of you are experiencing but every year the same things seem to be echoed. There will be people that say their phone shows scratches/nicks inexplicably and that there must be a defect because previous models did it do it. And that may be true for them but there is always at least one thread posted echoing the same complaint. Only thing that can be suggested besides the obvious (even though not loved by those that hate doing it...that’s using a screen protector of some sort and/or a case) would be to report it to Apple and determine if it’s really a defect or just bad luck. For those that are near an Apple store and feel like it’s a defect should go there and let them see the device and observe how the screen looks and then while there replicate the issue. If the screen is truly faulty it should be easy to make a new scratch/smudge/scrap appear if the only thing that caused it before was putting it into an empty pocket for example. Makes it difficult for them to not be willing to replace the device if you can show the issue happens. Probably not what anyone wants to hear but being able to show evidence absolutely helps more than showing damage after the fact and wanting them to believe the damage happened out of nowhere. Not saying any of you are lying but imagine how many people do or would claim scratches they know they created by being careless occurred out of nowhere.
I would be frustrated if it happened to me no doubt but I’ve been very fortunate. Never had a scratched screen or cracks on any iPhone. Yes I’ve dropped them countless times, tossed them with abandon, etc but I’ve also always used a screen protector (always cheap ones) and a case...usually an Otterbox Strada but I do so because I know that I always plan to sell my device and by taking these measures my iPhones have always looked like new making get top dollar (far more than any of these trade in offers ever give). Usually the first week or two has me using a cheap case to hold me over while I wait for the Strada or this time the Nomad folio to arrive while keeping a trimmed down version of the plastic that comes on the iPhone in place until my cheap $5.99 3 pack arrives from Amazon in place to keep the screen pretty safe. I say all of this to say that I have been pretty lucky to not have an issue on any of my iPhones or the others in my home (iPhone 11 product red and 2 iPhone 11 pro gold)...although I did have a mini scare when I dropped a thick heavy palette corner down directly on my iPhone 11 pro Max gouging the plastic and making me terrified that I had taken a chunk out of the screen. Thankfully no damage to the screen. No scratch or anything. That was pure luck because it absolutely should have had some significant damage if not a full fledge shatter. Definitely made me think long and hard about adding AppleCare+ immediately 😂
Hope you all are able to get some assistance with the scratches but if not...consider a screen protector at minimum. The cheap ones I use don’t alter the feel of the screen at all. Again, I get these not so much for concerns about cracks but to ensure the screen doesn’t get surface scratches solely for preservation of resell value.
