The first thing that strikes for Samsung Galaxy S6 smartphone is that it has been built from scratch. Yes, it has not inherited anything from predecessor and looks quite promising. More to this, the device is equipped with all-metal body. This may surely wrap up the earlier complaints by many that Galaxy series smartphones look very plasticky. The device comes with a 5.1 Quad HD Super AMOLED display providing resolution of 2560 x 1440. It gives pixel density of 557 ppi. Samsung Galaxy S6 runs on the latest Android 5.0 Lollipop and is mounted with a 16MP primary camera and 5MP selfie camera.
