"Wild" seems like a stretch. I feel like it shouldn't be too hard to believe that some people drop their phones occasionally, and it's a reasonable concern when it's likely to be with you everywhere you go.
Edit: sibling comment is correct, sketchy pockets of athletic shorts are a major offender. Actually it bothers me way more when my car keys fall out of those.
I never used a case until I got a Galaxy S9; that phone was like a greased eel. Went from dropping my phone zero times in 8 years to 5 times in one week.
I stuck on a MagSafe metal sticker thing on the back and that little bit of greebling makes me feel a bit better holding it.
My phone case has saved my phone many times.
Heck, my bike helmet has saved my head at least 3 times.
Survivorship bias /s How do you know it wouldn't have survived without case? I drop my phone on nearly daily basis and since 2007 only cracked one iPhone screen.
The thickness should be from the front to the back of the camera lens, not to the thinnest point they can find.
I would gladly ditch the case if Apple had a strong mounting system integrated into the phone (MagSafe has nowhere near the resistance to shear forces sufficient to hold a phone over bumps on a bike.)
I suppose I am looking for the phone equivalent of a camera thumbscrew mount. If Apple iterated on MagSafe to include an actual mechanical fixture as part of the attachment, I would buy that phone right away so I can avoid using these crappy pieces of rubber/plastic that degrade so much more quickly in appearance than the phone frame rails.
Cases are dirt cheap, if you're paying over $30 for one you're probably overpaying. The expected value of a screen repair, not only the cost but your time makes it a no-brainer.
People need to get a grip. ;)
