• The Brief: Friendly Performance

    As a consumer-oriented Android smartphone, Evo needed a friendly personality to differentiate from its Windows-based business-oriented counterparts. However, being slated to be the world’s first 4G superphone, it also needed to hint of performance and features. The design uses a crossover between a strong, chiselled shape and a soft, pillow-like back surface to achieve this hybrid personality. Reveals and detail callouts give added depth and notions of a powerful inner core.

    Split Lines: A Problem used as an Opportunity

    Battery door split-lines are normally put on the sides of a phone to try to hide them because they look cheap and undesirable. I thought the split-line could be a nice design element if proudly used on the back surface instead. This gave the phone an added flavor of technical crispness and made the sides look clean and solid, reducing the associaton with cheap, molded plastic products.

  • Visual Slimming: SmartPhone on a Diet

    Additional requests for a bigger battery, integrated kickstand, 4G antenna system and bigger speakers made the phone look thicker than desirable. We added a high-contrast split on the side as a visual trick to maintain a thin, sleek aesthetic. This also created an impression of a thick slab of display glass that wraps to the sides and a back housing that had a sheet-like gesture, which was a fresh aesthetic.

  • Big Camera Component: Feature Emphasis & Problem-Solving Through Form

    One of the biggest challenges was to include an 8MP camera – it was a huge component. While it was a requirement to highlight this key feature, it shouldn’t feel unnaturally big or loud. To create this balance, I needed to find an aesthetic solution that would somewhat mask the component size, and one that would look honest and purposefully ‘camera-like’.

    This led to a spherical design that partially protrudes the outer surface of the phone. It created an interesting and iconic character akin to an eyeball sitting in a socket. I liked that it had the notion of the phone as a housing for powerful, intelligent, internal components.

  • Becoming an HTC Signature Camera Detail

    The EVO camera solution proved to be a visually effective solution for wrapping big camera components. At the same time, it was a good balance between being iconic and honest. It has subsequently been adopted (and evolved) by HTC, and reapplied on several production phones – becoming a signature camera detail of the HTC 2010 design language.

  • Final Production Version

    Evo was launched by Sprint on June 4th, 2010. The full black version as the default and the white-black version shown here as the special edition. It broke first day sales records for Sprint and also became Best Buy Mobile’s best selling device. On June 19th, 2011, Evo broke the ‘5-million units sold’ milestone and became Sprint’s best selling device in history, as well as HTC’s most sold phone ever.
