1. Back up your data to PC via Windows Explorer or Smart Switch (since you use Galaxy 4). After update, restore data back.
2. You can try some methods to free up Samsung phone space. However, if your phone really has limited internal memory, it might be not worth to get little free space by deleting the files which you like. You can buy a micro SD card to increase phone memory and move media files and some apps to SD card.
