I understand that jacket pockets, jeans, bags, etc do contain abrasive particles like sand, dirt, fibers, etc. but it’s kind off impossible to avoid exposing the portions not covered by screen protectors to those elements in day to day use and I am just concerned about damage to the glass covering the camera and sensors under “normal” conditions (of course if I put the phone in my swim trunks pocket at the beach it will unavoidably scratch just as would the screen protector and case). This has never been an issue on my current iPhone XS Max as well as previous generation iPhone’s but it seems like the glass on the new 11 lineup is more prone to scratching although more impact resistant. Keep in mind Apple is claiming the “toughest glass in any smartphone” which does imply some abrasion resistance otherwise it would be “strongest” or “impact resistant” glass.
I am not going to argue Apple’s choice of marketing terminology because they have a whole team dedicated to just that with way more knowledge of the issue than me, all I am saying is that for a new iPhone marketed with “toughest glass” I find myself worrying more than on previous generations about scratches on exposed surfaces not covered by screen protection that could cause malfunctions under non-abusive normal day to day wear and tear.
By definition:
tough /təf/ adjective
superlative adjective: toughest
(of a substance or object) strong enough to withstand adverse conditions or rough or careless handling.
I would think dust and micro abrasive particles inside a pocket would be covered under “adverse conditions or rough or careless handling”
