After a long period of minor advances in innovation, smartphones deserve to have close attention again.

You’ve been willing to put up with the relatively poor battery life of foldables, smartphones have become boring slabs of glass. From one Apple iPhone or Samsung Galaxy S series device to the next, there have been few meaningful changes in at least half a decade. But things are about to change.
Manufacturers such as Apple, Samsung and Huawei found that the only way they could make their products stand out was to design unique camera bumps — in Apple’s case, a distinctive triangle of lenses; in Samsung’s, a vertical lens arrangement. It’s basically the only way to see at a glance what phone someone is using.
