Device probably already used

When I turned on this unit for the first time (device sold by Amazon.com and not a third party), it was Chinese and I had to look a long time to put it in French. In addition, there were two dead pixels and for this last reason, I did replace the similar, but white.
When turning on the replacement model, I had several screens to easily set the machine, which makes me think that I have the phone returned for dead pixels is no longer set at the factory and had been most likely already used then put back into the new appliances distribution channel.
Moral: go around the product receipt, check that it is indeed a new, if not return Amazon
