I love this game and have been playing on this app for about a year. Last night my phone shut down completely. It was clearly on because even though the screen was dark it was some type of light coming through. Took it to the store just now and the final prognosis is that there's no saving my phone. I told him I was playing this game when it happened and he said most likely it was the ads. I knew pop ups were annoying but never knew they could lead to a situation like this. Don't download this.
