How is this most valuable startup doing its fast penetration into a competitive market for smartphones? I suspect its main secret is not simply high function at a good price because that exists already. I myself just moved to an Android powered LG Tribute phone that is fast and running the latest version of the Android OS. It was on sale for $39 at Virgin Mobile.
What is Xiaomi also doing?
I would say they are doing customer service. They use a customized version of Android on their phones and they apparently update this OS frequently based on the requests from their customers.
Well, fancy that: good customer service.
