Might be hard to believe, but I’m responding from a phone with just about as many cracks in the screen, and luckily mine is still working just fine. I’m definitely not missing chunks of my phone like that though LOL!

Every single broken screen is its own unique situation, sometimes you get lucky and a zillion cracks won’t cause any functional problems, other times just one or two cracks kills the whole thing.

It all depends which layers of the screen got cracked, and it really helps improve the chances of it still working if you had a screen protector on it prior to breaking it.

TL;DR - Who knows, the image seems fake to me as well, but it’s not out of the realm of possibility that it just may be real too. Even if that image is real, that touchscreen might be just as dead as that battery…
