A mysterious bug that almost certainly happens?

My smartphone. I launch Choco Run -> Select an area -> Enter a room. Up to this point, it's stable. Here's the problem! When the screen is black after entering and I press the zoom in/out button, there's a high chance, like 99% probability, that the game itself crashes. I don't know if it's a bug or if my phone's specs are insufficient, but I'd like to know if anyone else experiences this same type of crash...
