You can update your Galaxy S5 using two methods: Kies or Samsung’s FOTA (Firmware-Over-The-Air) service. To update your device via Kies, connect your device to your computer and use Samsung Kies 3. If you don’t like wires and stuff, you can use the FOTA method. To download and install the firmware via FOTA, go to settings > system > about device > software update > update.
