I downloaded Duel Quiz and I can't open it, the format is too large, I can't click on the functions at the bottom of the game, please help me resolve the issue.
You've said it all.. The game is too big. Or maybe it's taking up too much space? Try deleting apps that you don't particularly care about. And if it still doesn't work, you can always re-download them later (be careful not to delete something that might cause you to lose all your data).
