Have not purchased from Amazon tablet. I do not really know what to make of the device. I have as a comparison only my Sony Z2 mobile phone. And since I have to say that the Z2 converts any "instruction" immediately and without Rucker. The Samsung Galaxy Tab Pro 10.1 Unfortunately not. Even me disturb the non-erasable and applications from Samsung Apps! If only disable this and their whereabouts in the Tablet storage. Positive I like the camera of the tablet's suitability as a book reader, despite the size and the Gewichtes.Zum allegedly slow load I have to say that I invite it to the charger of Sony and this has been going faster than the supplied. Remains an ambiguous result for me. Had me for the sake of performance but Sony should buy Z3 Tablet.
