Mobile phones seems to be part of our bodies. Almost like an extended organ. Proper functioning of this organ is obviously important to us but more interestingly its important to emotional health people close to us. If it doesn’t work for extended period of time, our temporary unreachability induces fear in closed ones. If the connection isn’t right or our voices cannot be heard correctly, that induces irritation or frustration in closed ones. Buying a shinier one can even be used to display our monetory health, hence playing a minor role in sexual selection (although that can be said of any personal costly object).
It used to be a tool just like any other humanity invented and enjoyed. But its not just a tool anymore. Its one of our organs which we need to take care of by keeping it safe and upgrading to better versions.
