Following up on my post yesterday about modern iPhones and scratch resistance, and my personal habits of (a) almost never using an iPhone case, and (b) never setting the iPhone face down except on soft (cloth) surfaces.

I should have anticipated this, because I’ve had this conversation with real-world normies repeatedly in recent years, but I got a bunch of questions from people who say they’re wary of ever putting their iPhone down on its back because they’re worried about scratching the camera lenses. That’s not a silly thing to worry about. It looks like those lenses are glass; glass scratches; and it sure seems like a scratched camera lens might forever ruin all the photos and videos you take with the camera.

There are a couple misconceptions here though. First, the glassy flat circles exposed on the back of your phone aren’t the camera lenses. Those are covers over the lenses, which are smaller, spherical (convex, not flat), and recessed. You can look through the covers and see the actual spherical lenses inside. The exposed lens covers are made of sapphire, not glass, and are thus incredibly scratch-resistant. They’re by far the most scratch-resistant parts of the phone. I’ve never once found even a tiny scratch on any of my iPhone camera lens covers, and I’ve never taken any particular care to avoid scratching them. I mean, I don’t drag the lenses face-down on surfaces. I’m not trying to scratch them. But I set my phones down on hard surfaces lenses-down all the time and they never seem to pick up even fine scratches.

Zack “JerryRigEverything” Nelson is the guy on YouTube who makes videos where he scratches the hell out of products to see how durable they are. (And he bends them, burns them, and abuses them in other gruesomely creative ways.) In his iPhone 17 Pro video, starting around the 4:10 mark, he tries scratching the sapphire lens covers with a sharp razor blade. No effect. Sapphire is far more likely to shatter than scratch, because it’s so hard. (You may recall that a decade ago Apple pursued using sapphire for the displays of iPhones but it didn’t work out.) Don’t try scratching your lenses with a diamond hardness pick and you’ll be fine.

Also, believe it or not, a fine scratch on the lens cover will almost certainly not affect image quality at all. Try sticking a strand of hair (which is probably much thicker than a typical scratch) to the surface of your iPhone 1× main camera lens. Take a picture. Clean the hair off the lens. Retake the same picture. You almost certainly won’t see any difference at all. Here’s a great video from DPReview back in 2020 showing just how much dust or scratching you need to put on the outside of a lens to degrade image quality. It’s counterintuitive but the surface of the lens is not where light is focused — the sensor, inside the camera, is.

This page from Google Design on their “Material 3” UI language came to my attention after my snarky post about the ungainly new to-do app they bizarrely bragged about on Twitter/X this week. I don’t think this “Material 3” page is new — I think it’s a few years old — but I’d never seen it before.

First, it’s crazy that (in desktop browsers with a mouse cursor) they change the I-beam cursor for text selection to ... a circle. I guess it looks kind of fun but the whole point of the I-beam cursor is to enable precise character selection. They changed that to something that makes precise selection as difficult as possible. It’d be better to just use an arrow pointer than to replace the I-beam with a goddamn circle. This, from the UI design team.

Second, this paragraph made me honestly wonder if I was reading a spoof, a years-old unfunny April Fool’s “prank”. But as far as I can tell this is totally straight, not a prank:

These factors can be quantified in users’ responses to new M3 Expressive designs. We found a 32% increase in subculture perception, which indicates that expressive design makes a brand feel more relevant and “in-the-know.” We also saw a 34% boost in modernity, making a brand feel fresh and forward-thinking. On top of that, there was a 30% jump in rebelliousness, suggesting that expressive design positions a brand as bold, innovative, and willing to break from convention.

Nothing says rebellious and “in-the-know” like assigning precise percentages to “rebelliousness”, “modernity”, and “subculture perception”.

Update: Believe it or not there is video of the Google Design team putting this research together. Worth a watch.
