I believe only apps larger than 1 gb can be saved to the extsdcard.
I just bought NOVA 3 from the Play Store when it was on sale this week, and my SIII would not allow me to save it to the SIII card. It's 1.2 GB I believe.......
I just got my S3. I am coming from an HTC where you downloded apps then saved it to your sd. How do I move apps and downloaded games to the micro sd card?
