I managed to crush one once. It was in a laptop pouch in a backpack with a couple of robust plastic binders and books in the main compartment, and I must have thrown it once too often into the corner/side of the corridor, having other things to do. I assume I cracked something inside, maybe even the PCB or so, as it looks dead. I might check if the screen is still alive, as it might be an issue with the logic board instead of the screen, as I now remember it (it's been a couple years, it was an iirc. 3rd gen low-end device).
