Samsung Galaxy S4: move apps to SD card by using FolderMount

As you might know Samsung Galaxy S4 is available in varied internal storage capacity (16/32/64GB), but the most popular model is the 16GB, which is undoubtedly insufficient for those who wish to install a lot of apps and games. Let me use Modern Combat 4 for example, this app needs more than 2GB for storing app data, and all things are kept on Galaxy S4 internal SD card.


There are several methods to free up some space on Galaxy S4’s internal memory, such as removing a couple of apps or even get rid of all bloatware/pre-installed (Samsung/Carrier) apps. But a majority of users believe it isn’t enough, since this method only able to clear up a little space. The right solution for this problem is by moving apps and the data into an external SD card, unfortunately Android 4.2.2 (Jelly Bean) does not let you, but we could get it done by utilizing third-party apps.
