your music and photos will be aready stored on your sd card, if you've moved all the apps you can to the card there's no much more you can do unless you root the phone and that,s not easy, i've tried dozens of times and nothing works, get rid of all the apps "you" have put on and don't use that often. don't bother with cc cleaner, excellent on a pc / laptop but no use on a mobile, go into settings look for storage & usb click on internal storage see your cached data click on it and clear it (i will go down to around 1.66mb and that's all you can do
