For 13 a simple functional protective case. There are two sets of four Velcro plastic corners with different Clamping height included. For S7852, the low suitable. Fit, pinched and protects! The inclination I do not unstable since at the lower edge of the tablet support two Velcro strips are attached, so that one the slope can adjust continuously. 5 Stars Postscript, two of the plastic corners you have for microphone or headset jack a little Adjust the side (file or smaller diagonal cutter). For the rear camera is there any aperture. My vote remains.
