I'm just a fellow player who has been playing for years, read many posts on game problems and experienced even more of them. After reading all the details you provided, I feel like this is a fairly common problem that happens a lot with Android devices that most call a 'Connectivity Issue'. Basically, there's nothing wrong with the app

I would suggest going through this Game Guide post and trying all of the options listed:
