Square Enix will release Final Fantasy XV for smartphones in February

Mobile version of Final Fantasy XV: Pocket Edition, as reported by the developers, will be released on February 9, 2018.

What changed

In comparison with the same game for the PlayStation 4 and Xbox One, Final Fantasy XV, iOS and Android platforms, only the visual component has changed, and the plot has remained unchanged. The graphics became more cartoonish, partly similar to Final Fantasy VII of 1997 or to World of Final Fantasy, which was released for PS4 and PS Vita two years ago.

Wherefore

Starting with the release date, all 10 chapters will be available for download. The first one is free, but for others you have to pay: the second and third parts are valued at 0.99 euros, and the rest - 3.99 euros or dollars.
Final Fantasy XV: Pocket Edition on Android and iOS can be downloaded to Google Play and the App Store .
