Protect your Samsung Galaxy Tab S4 with the Just in Case Premium Samsung Galaxy S4 Book Case and get started with typing reports right away. Simply connect your tablet to the keyboard using Bluetooth. Thanks to the auto wake function you unlock and lock the tablet by opening and closing the cover. The cover does not make your tablet unnecessarily thick, so you can easily carry it in your bag. You also take pictures with the tablet in the case, because the case has cutouts for the camera and buttons.
