The Tab S disappointed me somewhat. Samsung sends a great hardware into the race with a sharp crack Amoled display in ultra-flat and lightweight housing with Octacore processor. But then and even then it may not be that scrolling jerky. The browser stutters, the S-Planner fidgets, Taptu wobbles. Few apps scroll fluently. This spoils the mood. Although there with Hancom Office a very good office, but since Android 4.4 Kitkat may or may Third Party Apps (ie additionally installed on the PlayStore Apps) no longer describe the SD card. This is completely pointlessly, since the Tab S has only 16GB memory. This tarnishes the otherwise good mood on the device. The great hardware is not everything. The permanent stuttering, an almost superfluous SD card and the non-uniform in the user interface to the Android and Samsung apps make the overall system cuts both ways. There simply is not enough to grab a few good hardware components in a thin case and then to market it as a high-end. The workflow on the unit ultimately determines the rating - and draws from at least 2 stars - even if the device otherwise top appears.
