iLLMATICxKING, There is not much difference from putting apps on SD Card or Internal Memory, providing if your SD Card is fast. There is no difference when using Class 10 SD Card but you can notice the slowness if using Class 4.
Another thing I'm experiencing is the internal memory is considerable more reliable. My SD Card has data lost once in a while, more often than I hope. If you have apps installed on an no so reliable SD Card like mine, you will keep getting some grey out app icons on your phone, which means the apps is actually lost.
The only way to clean it is install the app again (cause you to have the greyed out icon, and a new proper icon) Uninstall the app (removes both greyed out and proper icon), then install it again (finally having only the proper icon remaining on the phone)
If you have a reliable Class 10 SD Card, there is no difference at all.
p.s. Don't buy the Samsung Class 10 32GB Micro SD. That's what I'm using.
