Samsung nets exclusive supply for the Fold 2's bendable cover glass revolution

There was speculation back in the summer that Samsung has decided to move on from the controversial plastic cover films for its bendy phones like the Galaxy Fold to... real hard tempered glass like, you know, on those outmoded rigid phones. Wait, glass can't bend you say?

Well, ultrathin and ultradurable one apparently can, and Samsung has wiggled its way into an exclusive long-term contract with its local manufacturer DoInsys, reports Korean media today.

The Fold's durable polyimide (PI) film that is flexible but prone to scratches and not as premium looking and feeling as glass, is on top of that supplied by the Japanese from Sumitomo, and has fallen under export restrictions under the ongoing trade spat with Korea. Comprising the top layer of the Galaxy Fold's flexible display package, it is actually an integral part of the screen. That wasn't quite clear on the preview units Samsung sent out, and some tried to peel it off, ruining the handset's display in the process.

While Samsung fixed the problem by extending the PI cover over the corners of the upgraded Fold, so as it doesn't look like a screen protector, it has apparently decided to move away of such films in the future, replacing them with a more orthodox tempered glass. Apparently, the notorious rigidity of a glass structure isn't as valid for glass that is 100 micrometer thin, and that's exactly what DoInsys has developed, potentially going down to 30 micrometer even.

Since such a cover would be of interest not only for foldable phone displays, but anything that can potentially employ flexible screens, including laptops, Samsung has reportedly secured a long-term exclusivity contract with DoInsys for its ultrathin glass sheets, as Chinese makers have already spotted the opportunity, according to one industry watcher:

Production is ramping up significantly as we speak, say industry sources, and Samsung is even fronting DoInsys with investment into equipment and facilities to ensure steady yield in time for its rumored Galaxy Fold 2 release in the spring. A bendy glass cover would be a sight to behold, and we can't wait to try one out in a trimester.

Looking forward to Sammy merging the S-line and note together

So.... why did they release the first fold with plastic when shortly afterward foldable glass would be available? Surely it’s better to let Huawei be first with their failure and then storm in with a completely new “Galaxy Fold” with a name people don’t associate with scratching under a fingernail.

Considering the lack of issues we've been treated to with the final release of the Fold, it seems to be getting the job done. And remember: it was months late to market due to the pre-release issues. Samsung likely didn't plan the short update cycle.

It’s still quite fragile as people have pointed out. And it remains to be seen where the long term reliability is going to look like. The one thing I’m interested in seeing is the 3-6 month usage. Because from the JerryRigsEverything video you can see how a small amount of dust or dirt can cause some pretty noticeable issues. And right now I would imagine people are able to keep their phones relatively clean of that, but it’s bound to happen at some point. That and it’s only a matter of time before someone accidentally pokes their screen with a fingernail.

One things for sure. If bendable glass doesn't pass zack's scratch test. There's no way everyone would buy a foldable smartphone.
