We earlier wondered why Huawei’s Emotion UI ditched the app drawer in favor of a different home screen setup. Over at the IFA 2012 in Berlin, our very own Darcy LaCouvee had the opportunity to interview Huawei’s phone unit vice president Lars-Christian Weissewange, where the executive explained the concepts behind Huawei’s design decisions.

Weissewange explains that the Emotion UI does away with the complexities of vanilla Android, but kept the flexibility associated with the mobile OS. For instance, the home screen was combined with the app launcher. Everything is icon-based, and all apps are on the first layer.

He highlights that this “completely changes the way the OS operates.”

Additionally, Weissewange said community is important to Huawei, and the company accepts contributions from developers and third-parties, and publsihes these in regular updates. But as for the lengthy phone release schedules and update processes, he says when they launch devices, they want it to be as “perfect as possible.”
