A future Samsung Galaxy phone (although likely not this Galaxy phone) could have a flexible screen that's unbreakable, delivering the first truly foldable handset. The Korean electronics giant said Wednesday that its recently developed phone panel has been certified by Underwriters Laboratories, meaning it's ready to start shipping to consumers in actual devices. Samsung said it expects the new panel to have applications in non-phone markets as well, such as automobiles, mobile military devices and portable game consoles, among others.

Samsung's efforts to make a foldable phone come as demand for phones slows down. It's getting harder for handset makers to differentiate their devices, and consumers don't feel the need to upgrade as often. In the fourth quarter, overall phone unit sales fell for the first time ever, according to Gartner.
