Li Ying Ming, the Soical Marketing Director for Chinese manufacturer OPPO, posted a series of mock-up photos to Sina Weibo showing the company's Android powered Find 5 handset running Windows Phone 8. The images do not represent an in development or planned handset, but do provide some support for earlier reports that the company is interested in making a Windows Phone 8 handset.
As noted by LiveSide.net, OPPO is better known for their Blu-ray players and other consumer electronic goods, launched their first smartphone, powered by Android, earlier this year. It was notable for being one of the first devices with a 1080p screen, something that has now become more common on high end Android handsets, and is likely to be supported on the Windows Phone platform before the end of the year, as part of the GDR3 update.
The evidence for OPPO's interest in Windows Phone is relatively thin, but is part of a continuing theme of under-the-surface interest from Chinese manufacturers such as Phicomm, Unimobile, and Coolpad.
Despite these reports and other rumours of interest, there has yet to be any Windows Phone 8 handset announced by a manufacturer outside of the four official launch hardware partners (Nokia, HTC, Samsung, Huawei). This may change as we head into the second half of 2013, especially with Microsoft scheduled to deliver broader hardware support (e.g. Qualcomm MSM8974 and 1080p screen resolution), but for now the push from Chinese manufacturers that we expected to arrive this summer has yet to materialise in a meaningful way.
