there are lots of things in this world that can be fragile under special circumstances. eggs, christmas ornaments, human bones, automobiles, relationships....phones are generally not fragile when used as prescribed.
the difference between iphone x fragilegate and samsung exploding battery gate is that exploding battery gate occurred during normal use. breaking the back glass or front glass of an iphone x will not occur during normal use, you have to either decide to break the glass and take action to do so, or, by accident drop it where there is a risk of breakage. that risk cannot be out-engineered when humans are involved.
individuals are benefitted by being able to choose their own personal sense of risk acceptance, and fortunately Apple as well as an unlimited open market has respided with a plethora of risk mitigation add-one suitable for the clumsy or just those who are extremely adverse to risk.
i’ll use the phone naked like i always have since model 1, enjoy it for what it is.., th first scratch hurts the most but after than anxiety or even thinking about the polish fades away for me... i’m more interested in what the phone does after the newness wears off and les about how scratch or ding free i’ve managed to keep it, it that’s just me.
tl:dr -nobody would put up with an unbreakable phone.
