As Samsung / Android users, I have had enough of these products permanently. The good reviews for the Nokia Lumina 635 I have believed, and have not been disappointed. I am even very enthusiastic of this Smartfon. Technically in very good state, neat-looking and easy to use and all at an unbeatable price. What more do you want. Addendum: After I have the equipment now used 7 months, and was quite satisfied, recognize the SIM card reader 1 my SIM card is no longer (it is at low price ??). Demand from Amazon and initially straightforward and user-friendly statement. I should send the unit, a pre-paid label was provided. Everything so made. Today info from the repair center of Amazon maintain that no longer functioning SIM Reader is not subject to the warranty and therefore only a chargeable repair was possible, which was then offered to me for 62.23 euros. I refused. Thanks Amazon. When you order anything I sure where a guarantee can play a role. Already got me another Smartfon brought the media market.
