Phone crashed after 4 months: running but the screen is all black, possible to use it. Purchased through a marketplace seller: REDCOMSHOP, foul about the service and no customer service !! The phone comes as Chinese (not shown on the product or on the invoice) as soon as he got there a problem, REDCOMSHOP, the only time they responded to my message after 3 raises (regardless reactivity !! ) have returned to me so SAMSUNG being Chinese, the warranty is not guaranteed and they are well aware of (the product does say '2-year manufacturer guarantee'). AMAZON does not ensure the role of third parties and does not want to intervene. Result: Now, none of the two do not give signs of life, despite my reminders. So I lost 550 for 4 months! SCAM, SELLER NEvER !!
