It's been a while the new Samsung flasgship Galaxy S5 is introduced and first ported system app from this device are already out and available for other devices. If you want to try them out, just give it a go and see how th new UI of SGS5 looks!
First of all, ensure your device is running on the newest Android version (KitKat), otherwise the apps will not work. Note also, some of the apps might crash sometimes or just don't work at all. It's all kinda experimental now.
You may experience problems with S Health application and if you don't own a Gear Fit, don't even install the Gear Fit manager because it useless.
