HTC China president says Windows Phone 8 models with larger screens are in development
During the chat, Weiguang let it be known that sales of the first Windows Phone customized for the Chinese market, the HTC Triumph (same as the HTC Titan), met expectations but the bar had been set low. Still, the experience helped HTC prepare for Windows Phone 8. The executive said that it has always been HTC's intention to develop for both Android and Windows Phone. Before it produced the first Android model, HTC was known as a manufacturer of Windows Mobile handsets and has plenty of history with the crew in Redmond.
It is interesting to note that the executive praised the closed system of Windows Phone 8, saying it offers a more healthy, albeit slower, ecological development than the open source Android system. This has led to apps working more consistently across different manufacturer's models unlike the Android experience which he characterized as having poor compatibility issues and app development.
