The good: it worked perfectly 15 days, the 4G is real, autonomy is very important Downside: it crashed heating LOT no longer able to touch The positive: complaint consideration immediately ease back The negative: The device does not seem repairable The good: a new phone of another brand is offered me, shipped and urgentissime and it works perfectly So I am not at all sure of the reliability of this phone S6 but BRAVO to the seller who has quickly respond to my request for replacement, and sent me another perfect phone
