Chromecast has been one of the first and most popular devices that are completely run on software. Therefore, every functionality that the device provides is coming from the software. The device does bring out a change in how hardware or device can be entirely dependent on the software to run and function. However, the device does come with a reset button, which is the only physical button.
The button allows the users to factory reset the device if the software settings are not allowing the user to cast the content on the screen. The presence of a reset button on Chromecast shows the importance of a hard physical button and its reliability over software solutions. One has to understand that there is no way of accessing or resetting the device without any physical buttons in case it does not work properly.
It’s not that the presence of a rest button on Chromecast will lead to its regular usage. Any Chromecast user hardly uses it as the software on the device sets up everything during the first use, so that the setting works the same way in the future. However, this reset button’s presence is an assurance to the user that if everything fails, the reset button can be used to bring back factory settings and make the device work like new.
It does not matter which version of Chromecast you buy; it will always have the reset button. The button provides reliability as protective actions, and the users can be assured that no matter the software problem, this one-button will restore the device. It is why Google always has an emphasis on adding the physical button for its reliability.
