I live in China and almost everything I own is "made in China." Cellphone purchases depend upon the brand and quality. I have a Motorola phone that I bought four years ago in China and it's going strong! It's not an expensive one either . . . in fact, I chose the cheapest one there was! No camera, no frills, no nothing except calls and text. No problems!
Because I wanted a phone with a flip cover, I bought a Motorola V3 two years ago. Once again, no problem! It's been dropped and once I even spilled water on it . . . no problem!
Both items, made in China, with Chinese materials by Chinese workers.
Good luck!
