Today was supposed to be the debut of an expensive new version of the Motorola Razr with a folding screen. But it didn’t happen.

Earlier this year, handsets from Samsung and Huawei with flexible displays were delayed because of design problems. Motorola, by contrast, says it pushed back the launch of the redesigned Razr to give it more time to meet high demand.

The flip phone is back, baby! A vastly updated — and very expensive — 2019 Motorola Razr uses a flexible display to make an Android-based smartphone with the same basic design as the iconic handset of 2004.

It’s another option in the growing selection of foldable phones — a formfactor Apple is also considering.

Samsung is doubling down on its efforts to make smartphones with a folding display a thing.

During Samsung’s annual developers conference this morning, the company unveiled a new folding phone concept that’s drastically different than the Galaxy Fold. Instead of folding from a regular-sized smartphone into a tablet, the new concept folds into a clamshell, kind of like a futuristic version of Motorola’s Razr phone.
