Still has problems. Bad port.
It's a great game, but user interface was simply not considered when this was made for mobile platforms. All they did was make troops movable and reduced graphics and simulation to make the game run better, which it does. I does not, however, feel like it was play tested at all, as some things are very hard to do on smaller mobile screens (tile yields, city micromanaging, and placing tacks for district planning).
Also, screen froze for 7 minutes and then crashed on my free turn 51. Last time I saved was on turn 30. Definitely would not consider buying anything on mobile. It's a great computer game, though, even for laptop.
