Barely received, white spots appeared on the screen and the GPS was not working. After a first pass for service, the GPS does not always work. After the second pass, the phone was replaced and the GPS worked intermittently but ... After a few weeks of new white spots appeared on the screen. Exasperated, I have not returned to service. Finally after nine months starting up the phone any more, so I finally returned to the service that refused to repair the pretext that there were traces of oxidation. I said that my phone was protected by a plastic screen with a silicone shell and he never took the water. Only good point, the service is reactive :-)) concluded: "cheap is very expensive," we do catch me ... NB: the super autonomy trumpeted as "digital" and so on => completely bogus
