The flip cover from Samsung is a very good way to protect the screen. The reverse is however also protected, because unlike the original back cover, this one is thicker. The pressure points of the volume control button on the left are still good to use during the call, although the cover is closed. Protection on the edge there is not other than the left side. The color of this cover I personally like very much and fits perfectly with the black Samsung Galaxy S4 mini. The back cover is not to my knowledge from the known from the original back cover and extremely lightweight polycarbonate, but plastic. Nevertheless, the back cover is light, so the phone with a SIM card, micro SD card, battery and Flip Cover 131 grams. Original weighs 107 grams, according to Samsung mobile phone. One sees that the weight is indeed increased, yet still lightweight. That this protection is offered, none is likely to complain.
