Game is good and cool but has bugs

it's a very good game, but there's a little problem whether it's from my phone or from this game. sometimes there are places that cannot be pressed.

ok so this is a great game really, but sometimes The flicks or The notes doesn't work?, And sometimes The voices glitch , when ever level up my characters rank, it has 2 voice's, and sometimes when I play mv live most notes just, doesn't work, also, when I'm doing great or about to full combo a song, it also glitches, my  storage isn't really the problem, my storage isn't even full, and my phone is also new
