Actually, there is against the device per se, of the functionality and features, nothing to say. When, after just six months, the battery will no longer charge left, I sent the unit for, given by Samsung contract service provider in order to obtain warranty service. Unfortunately, I was told from there that it is a device that has not been made for the EU, and thus - according to the manufacturer's instructions (ie by Samsung) no repairs may be durgeführt. The unit was sold by Digital Sales and shipped by Amazon in Germany. Now I do wonder if Amazon ever pays attention to something, what it sells? How can it be that on Amazon Germany devices are sold and shipped, which have not been built for the EU market (and possibly not even technically approved for the EU market are)? Let's see how it looks now with the guarantee because the exchange time at Amazon yes is over. If it remains, it gets pretty easy Amazon.
