Can putting a phone on a chrome book crack the screen or put it in a black and glitching state *URGENT*?

My chrome book screen cracked as I put my iPhone on it to record something and basically it left a big f u by making a spot on my screen black and glitching the screen

Probably if you slammed the screen down on the lump of phone.

I don't see how putting an iPhone on a screen would crack it & damage it to the extent you say.

Was the phone over the keyboard of the opened laptop? Did the laptop fold suddenly? Was the phone left sandwiched inside? That's one scenario that could cause what you described.
