How did your phone screen break?

I accidentally tripped while walking on the road in the summer. The phone I was holding in my hand flew straight away. After drawing a perfect parabola in the air, it fell to the ground with a "pop". I quickly I ran over and picked it up, thinking that it was a good thing that the tempered film was attached. I thought that if I peeled off the tempered film and used the phone screen, it would still be fine. However, I never expected that the tempered film was fine and the screen was shattered. The quality of this tempered film is really good. It didn't work.
