Both variants (Classic and Frontier) feature a 1.3-inch Super AMOLED display. Under the display, it is a 1GHz Dual-Core processor, paired with 768MB of RAM memory. Storage is only 4GB but that is plenty considering what it can run. All of this is powered by a 380mAh battery and even have IP68 certificate for dust and water resistance.
However, the only real difference between the two are the Frontier’s sportier look and that it supports 3G/LTE connection. This makes it easier to use as a standalone device.
On the connectivity side, both support GPS, Wi-Fi, Bluetooth 4.2 and a hearth rate monitor. Also, they arrive with Samsung Pay functionality.
