Two years has done his service, the Samsung Galaxy Tab P6211 - today now, exactly two years and three days since delivery by Amazon - without falling, for no apparent reason, the unit turned off and can not be switched. Three hours on the original charger (without reaction, without any indication), long press on power, without SD card, with SD card: there is no difference - the screen remains black. Amazon can not help myself to a little over two years and at the infamous Samsung Support I need not ask well. Conclusions: The suspicion of obsolescence comes to mind. The next time you buy a cheap device. Since the failure does not hurt so. Too bad.
