Innovation is not a word I’d use to describe today’s smartphones.  Sure, Samsung tried something new with their curved screens, and some companies have toyed with ways to hide the front-facing camera, such as the pop-up camera, but that’s it.
And while smartphone manufacturers have been trying to breathe some life into the dormant industry, they’ve all been considered a gimmick or haven’t found their wings.  Take the Galaxy Fold, for instance, an innovative idea that failed with reviewers and is now delayed indefinitely.
However, there is one trend that, while I wouldn’t call in innovative, is a change that phones have been needing for quite some time: high refresh rates.
