It freezes too much to the point that it causes the app to stop responding and I has to close it and reopened it. This is more frequently when doing pvp, duels are ok but even then the freezing is more often. The latest update somehow it made the characters portrait go black during storyline dialog. I had to Delete the app and reinstall it. It did fix it at first but it returned worse that it was previously but the portraits weren't restored. It sucks because is a good game but is the truth.
