Hi Ben, From you above message did it sounds like you bought an S7 Edge? If so how have you found it and did you buy through Taobao? Cheers
I would advise only buying something like this on JD.com or T-mall (天猫) due to the issue of fake products which is prevalent on Taobao. Another local place in Chengdu to check out is 太升南路 which is known as cell phone street. If you go there and negotiate in person, do research before you go to makes sure you are getting a good price on genuine products.
