MyOS

Redefining the experience of smart feature phones through a modern, human-centered operating system.

Redefining the experience of smart feature phones through a modern, human-centered operating system.

MY CONTRIBUTION

UX research, information architecture, UI system design, and visual guidelines — including a custom icon set designed from scratch with original iconography guidelines to ensure consistency across the entire OS.

ROLE & CONTEXT

Lead UX/UI Designer, full ownership. Built a UI system from scratch for a smart feature phone — defining the design language, component structure, and visual guidelines used across the entire OS. Collaborated with Product and Development teams across France and China. 3 months.

CHALLENGE

MobiWire's feature phones suffered from outdated layouts and poor usability — reducing customer engagement. The goal was to deliver a smartphone-like experience on constrained hardware, without sacrificing clarity or visual appeal.

UNDERSTANDING

UNDERSTANDING

Feature phones remain vital in many markets but often lag behind in UX maturity. MobiWire’s OS had inconsistent layouts, confusing navigation, and outdated visuals.

Our challenge:

  • Modernize the OS within limited display and memory capacities.

  • Build a unified design system for scalability.

  • Reinforce MobiWire’s identity through refined, minimal design.

DISCOVER

DISCOVER

We conducted a full audit and user feedback review.
Findings revealed:

  • Poor navigation logic and weak hierarchy.

  • Low readability and inconsistent icons.

  • Inefficient layout patterns.


Benchmarking modern smartphone UIs inspired a simpler and more dynamic design approach.

DEFINE

DEFINE

We restructured the system architecture to improve task flow and feature discoverability.
UX goals focused on:

  • Simplified navigation.

  • Consistent visual hierarchy.

  • Scalable design framework.


This stage also redefined naming conventions and content grouping to streamline usage.

IDEATE

IDEATE

We developed low- to high-fidelity prototypes exploring optimized layouts and visual rhythm.

Key decisions:

  • Unified spacing and alignment grid.

  • Minimal color transitions for better focus.

  • Gradient accents to introduce visual depth within low-spec constraints.

CONCEPTUALIZE

CONCEPTUALIZE

A design system was created covering:

  • Iconography built on geometric consistency.

  • High-contrast color palette for clarity.

  • Modern, legible typography.


The gradient style became a visual signature, inspired by trend and market analysis.


INTEGRATE

INTEGRATE

Close collaboration with developers ensured accurate implementation. I led the creation of UI documentation and conducted design–dev syncs for validation and iteration. Our agile workflow allowed efficient updates and precise alignment between design and build.

DELIVER

DELIVER

The new MyOS redefined MobiWire’s feature phone experience — clean, cohesive, and intuitive.
It now aligns with modern UI expectations and strengthens the product’s overall brand perception.

PROJECT INSIGHT

This project highlighted the impact of design systems and cross-team collaboration. The redesigned OS was implemented in ORANGE FRANCE and GLOBAL feature phone designs, manufactured by MobiWire, bringing a modern, user-friendly experience. The Senior Mode ensured older users could navigate the phones comfortably, combining modernity with accessibility.
