My Touken Ranbu Pocket app is actually 2.5 GB big now (downloaded from initial release), so it's possible that 1.9 GB space is not enough anymore.

The only way I can think to "fix" this is to have more space in your phone for the app and future updates since more updates = more game data to be downloaded.
