I asked the my Sprint rep this question in the store.
I'm not sure if this is the right answer but I was told that an app has to have the option to save to sd card
when the software was written. He said some do and some don't.
Also, he said that Samsung figures with the 16 gig internal memory (and 32 &64 gig for some lucky folks) that should be plenty of space for apps
because you can save your music and photos on the sc card which frees up space in the phone for apps.
I guess it depends on how many apps you want to put into the phone.
I have put several in, including Facebook and I still have 10 gigs left.
The 32 gig would have been all of our preferences but it wasn't available yet so we have to hope for now
that the 16 gig will be enough. So far, it seems fine for me.
JELLYBEAN is "supposed" to be the most sophisticated version of the Android Operating System ever developed. For it to not allow moving applications to the SD Card is asinine! There's no logical reason why Google would purposefully omit such a basic function from their operating system, is there?
