Google’s Chromecast is the epitome of a software-first device. Nearly all of its capabilities are defined by software, and usually not even software that’s on the Chromecast itself.
But the Chromecast, for all its hands-off simplicity, does have a single hardware button: an emergency reset button on the back. It’s a testament to the importance and reliability of physical inputs over software solutions.
Odds are, most people will never use the Chromecast’s reset button. Whether you have the original Chromecast, a second-generation model, or a 4K Chromecast Ultra, this button only has a single function: if all else fails, you can hold it down to factory-reset the hardware back to “fresh-from-the-box” settings.
