Earlier quoted context omitted.
Huawei went after Apple, including on quality. They were shot down right when their sales overtook Apple's (maybe a coincidence, who knows...)
Were they taking sales from Apple, to any major extent? Or just shifting around the Android market? If the latter, I can't imagine Apple'd care. Samsung's been doing the same thing (being the Apple of Android) for quite a while, and it hasn't mattered much.
I can't speak for China, but in Europe everybody I know who bought a Hauwei phone did so because they wanted a 'cheaper Samsung'.
