i got a new s3 last week and i downloaded a bunch of apps and put my music on the phone. it's 16 gb and now it says i only have 7gb of space. I bought a microsd card thinking that I can use it for storage but I'm not sure if i can. Anyways, before i downloaded a whole bunch of apps, there was this one game that all my friends play and it never lagged. Since i downloaded many apps and put my music, the game started lagging like **** so i turned on "disable hardware overlays". It helped but another problem came up, my youtube video lags while the audio plays. Is there any way to fix this lag or perhaps move all my music and apps to my micro sd card so I can clean out my phone memory? plz help thanks.
