20 months old, caseless and screen protector-less the entire time.
The glass isn't scratched, but there are dings here and a small crack in the case. Dropped it once and it landed flat on the glass front on a tiled floor. No damage at all.
The only thing hard enough to scratch it should be a diamond. I wonder if any of these scratches are from people that wear too much bling bling. I would be willing to help you of your problem if so....by taking your bling bling.
But here's a list of the hardest things anyway.
I understand that hardness is not the only thing that determines whether a substance can be scratched, but I find it interesting that current speculation suggests that the back of the new iPhone may be made of some kind of zirconia ceramic. Such a case would definitely be more scratch-resistant.
It's not just hardness that determines if one thing can scratch another. But here's a list of the hardest things anyway.
Are you saying that all bling is diamond?
I don't care what anyone says. Glass scratches with any hard object. It doesn't have to be diamonds. Diamonds can CUT glass. Anything hard can scratch glass.
Ever seen a glass counter top at a retail store? Lots of scratches. Keys, metal, sand, dirt, whatever - it will scratch.
I have one tiny one that's maybe a mm long or so; it can only be seen when held at an angle toward light and if you know where you're looking. That doesn't mean that it doesn't still annoy the hell out of me that it's there, of course.
Keys can scratch glass. Trust me. So can natural stone, rock and sand.
Scratching is one thing.
Cutting is another.
Ahh, your probably right. I think it's important to cover the glass regardless. The iphone is one of the few techy gadgets that actually has a decent resale value...No reason to not keep it in GOOD condition.
If you read the page I linked above, the 'hardness scale' it talks about scratch resistance with extra emphasis. It doesn't mean that if it's higher on the scale it is impossible to scratch with material of a lower hardness.
Along your line of thinking, diamond tipped hardware (like drill bits) will never need to be replaced. But if you look, professional safe crackers do through plenty of these things.
