The Galaxy C5 and Galaxy C7 are now official in China. The all-metal phones boast a slim build (6.7mm and 6.8mm respectively) and Samsung Pay, which works with the local AliPay service. They also work with UHQA audio using the Samsung Level On Wireless Pro headset.

The Samsung Galaxy C5 is available from Samsung's online store. It's CNY 2,200 for the 32GB version and CNY 2,400 for the 64GB model. You can pay Gold, Rose Gold, Silver and Grey color options are available.
There's a very short promo - until June 30 (tomorrow) you get a free 64GB microSD card and a transparent protective case.
The Samsung Galaxy C7 is not on the online store yet, instead you get the option to shop around your local retailers.

The Galaxy C series features metal unibodies and 1080p screens - 5.2" and 5.7" respectively - along with octa-core processors (Snapdragon chipset) with 4GB of RAM and 16MP/1080p cameras plus 8MP selfie cams.
