So I bought this keyboard due to the consistently positive opinions. It is not bad in principle, but when I plugged it on my tablet remains the battery indicator are (I let me show in percent) and the screen flickers and goes out just what is clear, because one gets no warning that must be loaded. Until I got the problem figured out, it took a few weeks, even have my tablet to Samsung for repair returned in the assumption that the battery has a damage. So who buys the keyboard and connect, please observe the time display of the battery. If that does not bother, but just simply reloading times, the keyboard is optimal. I'm going to then definitely get an original Samsung, which is compatible with the devices.
