You tossed it onto a tile floor, and it broke. That's unfortunate, but not entirely a surprise no matter who manufactured the phone. Glass is glass.
That's parent's point, don't use glass panels on the back of a phone.
I put half of the blame on reviewers promoting the idea that glass is "premium" and letting phone makers get away with this design choice.
Apple largely have the competence and the marketing power to make everyone believe that their premium plastic is amazing. In fact, they managed to make us believe that for glass which must be one of the cheapest materials on earth to produce.

You seem to have intentionally omitted some pretty important information there.
Which doesn't surprise me. I've dropped case-less phones on concrete and asphalt many times with only minor scratching to the frame. But I've also seen people drop phones onto decent-pile carpets and break their screens. It's hard to predict what will happen.
to get serious for a moment though, id like to go against the anti-glass grain by pointing out that supposedly, successive generations of Corning Gorilla Glass get stronger by some multiple each time, yet we see phone screens smashing with the same regularity because manufacturers are just using thinner panes each time (probably chasing thinner phones more so than some kind of planned obsolescence conspiracy, although both explanations are credible). so we end up with a tradeoff between thickness, durability and glass backs, but that beats having to rule out durable phones with glass backs entirely from being able to exist
