Samsung has teased the possibility of introducing a foldable flip phone. And if the latest leak is credible, then it might be the first foldable display to be made out of glass. Phone leaker Ice Universe (a.k.a. @UniverseIce on Twitter) claims that Samsung developed an ultra-thin glass cover for its next folding device—one that sports a flatter screen with fewer wrinkles. It's not as far-fetched as you think since the company has already applied for numerous trademarks around what it has called "Samsung Ultra Thin Glass." But as Engadget points out, we need to approach this leak with caution still. Because even with the photo provided, there's a possibility that it isn't even a Samsung device.
