Foldable phones and 5G devices were expected to be the matadores at the annual Mobile World Congress in Barcelona. And so they were, keeping the promise to introduce new form factors and design solutions – both material and immaterial – in the once innovative and now struggling smartphone world, an overly saturated market that’s experiencing its mid-life crisis. But this year there was more than foldable and 5G: on MWC’s stage, we saw new screen ratios, double displays and much more. It’s the reaction of an industry that has to show that there’s still room for innovation. And money to earn, of course. The promise was kept and new promise were made. Of many devices unveiled, very few of them, and none of the most interesting, are available right now. Something is changing in the smartphone world, but we'll have to wait a bit more to touch it by hand.
