At the reception, I was very satisfied with my purchase: Super portable, beautiful screen !!! In use, much less !! After only a few days of use, my phone began to be less and less fluid ... (reaction to a key after 30 seconds during a call number display but not recognition of contact ... ect) The icing on the cake: bug at the mail; a small "1" on the "message" when all messages are read! Even after reset bp .. Set near to 500Euros a phone that does not work correctly ... NO !! At that price, it is reasonable to want the quality !! Article sent to Amazon (thank you for this great customer service!) So I put 2 stars, because the design was great and a lot of interesting gadgets ... Damage :-(
