The iOS and Android versions of Final Fantasy and Final Fantasy II are full of problems. Lack of HD support, no tablet version, lack of content (bonus dungeons, bestiary, music player). And Square Enix don't appear to be further porting them unlike III and IV.

So really, the question is why? Is it possible for them to roll out some big update in the future to add HD support and more? Or is there simply not much they can do without re-releasing it?
