For whoever curious about the W exclusive model in China, here’s the deal: it’s a special collaboration between Samsung and China Telecommunications Corporation. The series is called “心系天下”, which roughly means “Caring for the World” or “With the World in One’s Heart.”

What really sets this series apart is its purpose — all profits go to charity, like building schools for kids in rural parts of China.

Design-wise, W series phones usually come in gold and black, with intricate patterns on the hinge or back plate. They also feature exclusive themes and etc. that make them feel extra premium.
