In the software department, the Galaxy S6 Edge runs Android 5.0.2 Lollipop with Samsung's TouchWiz interface on top of it. The improved TouchWiz interface will be stripped off unnecessary bloatware to provide a stock Android like feel.
Connectivity options include dual-band 802.11a/b/g/n/ac Wi-Fi, Wi-Fi Direct, LTE Cat 6, Wi-Fi hotspot, NFC, Bluetooth 4.1, A-GPS and an IR blaster. The device also comes with Samsung Pay, a smart wallet service that allows the handsets to act as a credit or debit card when tapped against a shop's NFC chip reader or used to transmit magnetic stripe data. So far, it is only limited to South Korea and the US.
