Here’s how you can safely and easily transfer apps from the internal storage to the micro sd card, on your Galaxy S4.
– Access your Settings by pressing the Menu button at the bottom left of your device or by accessing the dropdown Notification bar.
– Once in Settings, access the More tab to your right.
– Access the Storage option and observe how much available space there is on the device. If you have a lot of space available you may not need to transfer any apps at this time, but if you have a just a little space available, proceed with your micro SD transfer.
– Tap the Back button at the bottom right of your device to return to the previous screen and then access the Application manager option.
– Sort your apps by size by tapping the Menu button then selecting Sort by Size. This will order your apps from largest to smallest file. You probably will want to move some of the largest apps on your device to your micro SD card.
– Select an app that you would like to transfer to your micro SD card and observe whether you will be able to move the app. If the Android operating system does not allow micro SD transfer of an app, the Move to SD card button will be grayed out. If an app is transferable, the button will be bright.
– Tap Move to SD card button and wait for the transfer to complete.
– Move as many apps as you can to your Micro SD card.
To access files on your SD card itself you will need a file browsing app such as ES File Explorer
