Another factor working against Apple in China is the dominance of WeChat, a messaging, social media and payments app used by more than a billion people. It works on Google’s Android operating system as well as Apple’s, making a phone’s software less of a differentiating factor. “Why would people pay such a high price for an iPhone,” asked Kiranjeet Kaur, an analyst for the industry research firm IDC, “if, from a hardware perspective, there isn’t much of an upgrade from Huawei and, from a platform perspective, there’s nothing to lock people in?” In Europe, buyers of Chinese brands describe undergoing a sort of conversion. Irritating flaws in their iPhone or Samsung devices lead them to seek alternatives. Presented with unfamiliar Chinese products, they initially have doubts. But after a while, they get hooked.
