I bought this product in mobile paradise. Has it an original Samsung charger Russian characters? It is ever suspicious when a product is supplied without original packaging. Okay, that could be through OEM / Environmental / Amazon Frustfrei etc. a customer still it relies. But if you put an original Samsung charger into the outlet and it starts towards it to give high-frequency noises, then it is hardly an original product from a reputable manufacturer. Certainly it depends on from which dealer you receiving the product. I would like to spent a few more Euros and purchased directly from Amazon, but this article is currently not offered by Amazon.
