This is actually partially true. The only information you get from jerryrigs video is that the screen hardness is above 5 and below or equal to 6. The materials in our world are not all exact single digit, in fact most aren't. There are particles that are 5.2 or 5.56... now if the XS screen was with hardness of 5.8 and 11 is 5.1 - the XS one will resist the particles from the example, but the 11 screen will scratch. All that while both pass the 5 pick test and fail the 6. Hope that makes it clear for you.
Also I don't understand people here that used a screen protector from whole their life, stating that the screens are the same. Did you have personal experience? Did you try naked GG6 note 10 plus and then again naked the iphone 11 with the same usage to come here and state it's the same (while apple states their glass is a custom formula especially for them)?
This discussion is not about screen protectors or no screen protectors and the benefits/drawbacks from that decision. This is discussion about the less scratch resistant glass vs the previous years from people that used multiple iphones in the past, a lot including the previous year one.
Also in the apple ad that stated and I quote: "It’s tough out there" they throw with high velocity at the phone, objects that got metal and sharp parts (watch again with pausing) and on top of that that statement is general and not only for shattering, further implied with the water resistance in the same ad. It's not a shocker that everyone who likes to use his phone without protection and didn't have any problems in the past years will expect the newer one to behave atleast the same regarding scratch resistance if not better. Any recent phone on the place of the 11 in that ad will be in more danger of scratching vs shattering.
Edit: Shatter resistance should be chased for sure, but not to the point that the scratch resistance is so bad that it's basically a joke and the glass behaves almost like plastic. For those of you using a case and protector - the phone will survive no matter if iphone 6s or iphone 11, but 100% of us using our phones naked will get deep, wide and multiple scratches with careful use and fast. This is not how you engineer a phone, especially when you don't ship it with a protector and warning that you defo need to replace it if you remove it as the phone will scratch badly fast.
I personally won't exclude yet the possibility for a bad batch of phones/screens as the complains from back scratches are far less and far more in the numbers of every new popular high end phone release, while the glass should be the same without the coating (and that coating is surely not a fingernail deep).
