Cover synthetic leather and non-leather as advertised but considering the price it is not surprising. The 2 card pockets leave marks on the screen. A strong plastic smell from the cover even after one week of use. The Standby button is available, more complicated for the volume knob. The s-pen is still difficult to access and yet I have long fingernails, though the phone well protected and well held in place with flanges that keep all along the sides unlike those who only clipped in the 4 corners . It thickened still not bad phone. The 2 protective films are very badly cut: it lacks a few millimeters on all 4 sides and full of air bubbles pose! The first I had to throw it, the 2nd is in place until I bought well adapted protective films but does not hesitate to touch and use of the s-pen pen.le offered is much too large and almost unusable.
