Corning’s new Apple-like ceramic glass might save your next phone from disaster

While nice in theory it would reduce the stiffness of the phone. The "glass sandwich" construction needs glass on both sides to maintain rigidity. Having glass on one side and plastic on the other practically guarantees a cracked screen the first time any flex is put on the phone.

Edit to add:

I should have added that the glass is a structural component and not just there for looks.
I don't know if you know this but a lot of phones have and used to have plastic backs and are/were plenty stiff. Samsung briefly switched to that for the Galaxy S21 and the reason they switched back was because people complained about wanting "premium materials". Phones weren't breaking.

The ultra thin sheets of tempered glass in phones aren't exactly super rigid, and polycarbonate is rigid enough to make the sandwich solid

Plaster is NOT Portland cement. It used to be calcium hydroxide lime and now it's calcium sulphate just like the inside of dri wall
Well actually plaster is a bit like concrete, in that it names a class of materials.

There's plaster of Paris, which is the gypsum-based product made into plasterboard and is the main component of most modern interior finishing systems.
There's quicklime, which was commonly used as part of older lathe and plaster and is found in some modern plaster mixes.
There's cement plaster, containing Portland cement, commonly used as a render over masonry, inside and out.
There's clay-based plasters, which were used when lime was hard to come by.

Sure it is. As the original poster stated, walls in old houses were commonly covered in Plaster Portland Cement, aka "stucco". It's still widely used in construction, mostly for external walls.

my sit/stand desk surface is eeeeeevvvveeerrrr so slightly off level (tilted forward) probably from me leaning on it. I just poured a small amount of water on it and it's advancing at roughly 1 inch per 12 seconds, as a test.

My iPhone 15 Pro will sometimes work its way off the desk and fall to the floor. It's fucking insane.
If only they would invent some way of leveling furniture…

I often wonder why they don't make plastic screens with replaceable glass screen protectors. Scratch resistant and smooth to the fingers up top, and shatterproof on the actual expensive screen.
Maybe it doesn't work for some reason (visually less pretty?), or maybe fragile screens drive up profits?
They did, but they didn't sell. I worked for Motorola when we launched the Droid Turbo 2. Its whole marketing was shatterproof.

I loved that phone and my whole job was to show how indestructible it's screen was. I would constantly drop it. Let reps drop it. Let customers drop it. Chuck it across rooms. And it was eventually, after about 200 throws across a room, that the internals of the phone finally broke. But the screen still wasn't shattered.

So then I took it up to a second story at a Verizon Training Center and dropped it off. Screen still didn't shatter. It did scratch like crazy though, so you really did need at least the plastic screen protector on top. The top plastic layer of the actual screen was also replaceable. But it was a tricky enough replacement that most home users would probably mess it up and get bubbles/fit similar to what you get installing a finicky screen protector. Still nice to have a backup if you didn't use a screen protector and scratched your screen.

But yeah that'd be nice as a theory but in practice I'm not that organized. I just throw shit in a pocket 🤷‍♂️

Thirty years ago, if you told me that company that makes casserole dishes was going to be a tech giant,
Corning HAS been a tech leader most of the 20th century. Tom Edison's lightbulb glass, and cost-cut glass for the lamp industry. Pyrex(r) revolutionized lab-ware; its cheap-versions were fun at home, we make taquitos and quiche in 'glass' (but they don't sell real Pyrex now). The 200-inch telescope mirror at Palomar. (Quartz didn't work.) Noted for "...research and "disruptive" and "on demand" product innovation." Safer car headlight and window glass, though foiled by Detroit sleaze. Some low-loss optic fibers. And The Corning Museum of Glass which is/was fairly unique for Industry. Even in the end of the 20th century it got to be more Capital Manglement than glass, but everything is going to heck in a casserole dish.

Horseshit. I have had plastic body phones and they have been just fine

A lot of screens are plastic underneath, they're just laminated to the glass

This dramatically boosts strength, clarity, brightness, and sensitivity to touch

Consumers voted overwhelmingly against plastic (resistive) screens decades ago

Plastic backs however were a manufacturer-led "solution"
Plastic backs are awesome and so are plastic screens.

My N900 was one of the best phones I ever used. Plastic body, plastic and resistive touch screen. Could use anything to interact with the screen not just things with the right capacitance values. One time I dropped it while taking video on my bike, it hit the moving front wheel and flew across the parking lot. It was fine.

I feel like the glad sandwich excuse is letting them off. One side should be in tension and one in compression when bending. So it seems like it doesn't buy you much and there are many materials that are strong in compression as well. It seems like magnetic attachment should work with any non ferromagnetic material.

A big advantage given by removable batteries in a phone is that a drop becomes much less likely to destroy the phone. When a phone is dropped the energy imparted is1/2MV2, if the battery is removable most of the mass, the battery, is detached from the phone and can generally take care of itself. The rather more delicate and expensive phone is subjected to far less kinetic energy and is much less likely to be damaged.

I once dropped an old phone about 30ft from a scaff tower, it nearly survived. Once reassembled there was a black line on the display but it still worked. Don't talk to me about one metre!

What phones were you using with such a flimsy mechanism for attaching/containing the battery?

And this, kids, is why we don't put our keys or wallet in the same pocket as our phone. Phone in left front, knife and money clip in the right.
You still have the problem of dust and grit which can very hard & sharp. That said I am surprised there isn't a market for phone-safe pocket stuff, especially considering how big the EDC market is.

It shouldn't be too hard to make a money clip or a folding knife that cannot scratch a phone, keys are probably trickier since you have no control over manufacturers.

The optical properties of such a setup are presumably not as nice as if you have a screen laminated directly to the back of the glass.

I knew a guy who dropped his phone and the battery skittered off beneath some shelving, never to be seen again. I had a Samsung flip phone where the battery cover would fall off at the slightest touch after a couple of years. In my work experience, battery contacts are a source of unreliability.

Good riddance.

The last phone I had where I owned an extra battery or replaced the battery was a StarTac. And there were a variety between that and my first iPhone that still had replaceable batteries. Even when I had Blackberries, I used an external battery pack instead of buying an extra internal battery, because the external could also charge my iPod. Today, if I had a phone with a replaceable battery, I would probably still go with an external battery because it could also charge my earbuds.

I'm not saying no one should want a replaceable battery. I am saying that it would not provide any value for me.

Screen to the metal edge and flush.
That's only for scratching when face down on a surface, and for shattering. My latest phone has some light scratches despite being kept in a seemingly clean pocket without anything else - it's just invisible grit, apparently. I can't see one single scratch on the watch, though of course it's in open air - and sometimes bumped into things, but still.

everyone adopted the glass sandwich for a reason
1. Looks.
2. The revenue stream from also replacing the back of the phone.
If it was about structural properties, they could just use a piece of carbon fiber* reinforced plastic. It would be cheaper, tougher and just as rigid.

* I mean continuous fiber cloth - woven or unidirectional, not chopped fiber crap you often find in injection molded parts.

In its lab tests (PDF), Gorilla Glass Ceramic withstood 10 drops from one meter onto surfaces that closely resemble asphalt.
I'd be much more interested in a material that could survive a drop from two meters (or yards, whatever) onto a surface that closely resembles concrete, as that's about the height that my phone reached when it flew out of my hands after I stumbled on a concrete seam while trying to run for the train and look up the next train in the schedule at the same time.
