This is ridiculous! Oh wait, it isn't :)

I am always skeptical about these Chinese phones, I have a feeling that the way they can offer these phones for such a low price is by using the cheapest, nastiest, most unreliable passive components they can find on the street that day.

Imo it's like with Kia cars, not so long ago they were for laughs, but look at them now. People are always curious about my Mi2S, and if i show them, they are surprised if i tell them, it's just a cheap Chinese crap phone, because it feels solid. I had Samsung X820 for 8 years, because i don't buy fancy new models every year, so i can report how it will be reliable in long term.
