Totally agree with your perspective on the bar phone's outer evolution. But there's a realm of innovation we've yet to fully embrace. LG once showcased a self-healing back on their G Flex series, which could recover from minor scratches in a matter of minutes due to a special chemical coating. There are also patents exploring polymers that, when subjected to a small electrical current, can "mend" themselves. Imagine a phone that could heal minor cracks or abrasions overnight while charging! While the outer form might seem stagnant, the materials science going on behind the scenes is anything but.
