Sorry to hear that. I tried to replicate this error but couldn't on the 3 phones I use to test the game.
It may be your phone somehow or something I can't pin point, Godot is still improving as a game engine and doesn't handle some edge cases as well, and it may be related to some compatibility with your phone architecture even. Without access to your phone it is hard to know.
If you want, you can talk to me on discord in the report bug channel and we can try to get to the bottom of it. Alternatively or in the meantime, you can play the PC version.
I am solo dev, so I am limited in my possibilities, but I sincerely want anyone that wants to play the game to be able to.
