sourceThe glitch occurs about halfway through the game, during the fight between Kefka and General Leo in Thamasa. Kefka is supposed to kill Leo, but instead he just kills the game.
Square Enix confirmed it in an update on the Google Play store, promising a fix soon:
The following bugs have been confirmed and fixes are forthcoming:
- The game no longer crashes during the cutscene showing the fight between Kefka and General Leo.
- The icon for Sabin's Blitz ability now displays correctly.
- A misspelling of the term "Esper" has been corrected.
I say the major glitch is the graphics.
