I have only 16 gb of storage on my Galaxy s5, but the phone supports external sd cards up to 128 gb and luckily I have one :D
I plan to use this phone primarily for audio books, podcasts and other offline media.
But most of apps either do not support selecting custom folder for their content or even aren't moveable to sd card.
I found an app called "app mgr iii" which requires root access (thanks that I have it) and moves any app to sd card ignoring app's manifest.
Will it be stable? We will know in future. Now the av3715 app (Russian free audio books for #blind) successfully downloads its content and works after moving it to sd.
Other apps will be checked too soon :D
