Totally agree with sOin2you.
Manufacturing costs are sky-rocketing and with China offering a more affordable labor force (and a large one albeit) it only is sensible for the big brands to go that direction. And yes, when it's made in China, it means that it was assembled there yet the parts and the processes are dictated by the brand. Now China-made then you've got your Chinese brands. Frankly, I am quite amazed at some of the Chinese brands who have, not only developed a following, but have come out with great phones. I am a Chinese brand user currently because it does offer devices at a much lower cost yet with flagship specifications.
One thing buyers should remember when you are thinking of purchasing a Chinese brand, make sure you get the global version of the phone.
One has to be particular with the version. For every country, the version may differ depending on the restrictions in that country.
