No, I didn't explain properly. Screen is ok. It's just when you tap on powerup to upgrade it, the menu scrolls for just a little bit. It won't accept upgrade and behaves like there's nothing to execute. Like when you normally browse the web and tap on some text that's not a link or some other plain web element.
It does nothing but moves for a little fraction of space, like there's nothing to do after tapping.
I hope I was clear enough.
