UX Design for ASUS Zenfone Core Experiences
Defined system behaviors and core interaction flows for Zenfone’s native apps, including Camera and Caller, and contributed to UX guidelines for cross-app consistency.
Context
This was one of my earliest design projects. While the available documentation is limited compared to my recent work, I was deeply involved in the development of ASUS’s Android smartphones. My responsibilities included designing native applications, defining system-level behaviors, and supporting the integration between hardware and software throughout the product development cycle.
My Role
- As the UX designer at ASUS, I was responsible for leading interaction design, user flows, information architecture, and feature definitions across core Zenfone experiences.
- I collaborated with visual designers to deliver interface assets and ensure alignment with ZenUI’s overall design language.
Zenfone Camera Experience
As one of the most frequently used apps on ASUS smartphones, the camera was also a key focus for new product launches. I redesigned the information architecture and defined interaction behaviors to align with different camera hardware capabilities across Zenfone models. Based on product strategy and analytics, I restructured the quick access controls to better match user needs and usage patterns.
Based on product strategy and insights from Google Analytics, I restructured the quick access controls to better match user needs and usage patterns.
Created UX specification documents to define interaction behaviors and align with visual designers and developers.
Defined tutorial flow for Selfie Panorama
Redesigned camera IA and interaction behavior
Defined Portrait Mode UX based on camera hardware
Created onboarding for first-time camera use
Dialer & Call UX
Zenfone’s Caller and Contacts app combines contact management, dialer, and call log features into a single multi-functional experience. With over 20 million users and a 4.5+ rating on Google Play, it served as one of the core user touchpoints on ASUS smartphones.
In addition to the global version, we collaborated with Verizon to launch a customized North American release featuring VoLTE support, enabling a more complete voice and video calling experience.
I defined UI behaviors and flows for various VoLTE-enabled scenarios, including call state indicators, call history records, and transitions between voice and video calls. I created detailed wireframes and flowcharts to support edge cases such as multiple incoming calls or network-based prompts.
Defined flows for conference call merging and state transitions
Defined UI behavior for disabled video calling across app screens
Defining UX Guidelines Across Apps
Defined system-level UX guidelines across Zenfone apps, adapting Material Design to fit ZenUI.
Defined multi-window interactions and error handling
Specified contextual refresh behaviors
Standardized item selection and management
Outlined Action Bar layout and interactions
