i have had my Samsung sch-s738c since February. i loved it, i still do mostly. one of my biggest problems is the ability to use my external memory. i have one app downloaded that has aloud me to move and save somethings to my sd card. my apps and music and default for everything else i am unable to move. i have tried several different apps that are supposed to work. i am missing something rather important, the options to " move to sd card" button. it's nowhere. i can force stop, clear data, clear caches and that's it. i like my phone and i would hate to feel like bought a 16 gb sd card for nothing. please help me.
