Samsung Galaxy S3 Frontier

The Samsung Galaxy S3 Frontier has all the same features as the older model, Galaxy Watch, including GPS, NFC and heart rate monitoring, but also adds some key feature like the new fitness-tracking abilities such as measuring blood-oxygen levels and estimating your fitness, which is given via a VO2 max reading. One of the biggest plus points of the Samsung Galaxy S3 Frontier is the rotating navigation ring. With this feature in combination with the touchscreen, you can navigate through the menu both quickly and easily. Both these watches use Samsung‘s own operating system, Tizen OS, which  makes customizing the devises so much easier however on the downside is that Tizen OS isn’t supported by many vendors so the apps available are rather limited if you compare it to Android Wear or IOS watches.
