Huawei is planning a dual-OS smartphone launch in the US in Q2 2014, running on Android and Windows Phone. Taiwanese PC firm Asustek, meanwhile, has reportedly shelved plans to launch a device capable of simultaneously running on the two operating systems.

According to Huawei’s chief marketing officer, Shao Yang, in an interview with TrustedReviews, a dual-OS smartphone offers customers a useful extra option.

The marketing chief seemed to indicate, however, that such a device would be more beneficial for Windows Phone than Android.

“If it is Windows only, maybe people will not find it as easy a decision to buy the phone,” said Yang. “If they have the Android and Windows together, you can change it as you wish and it is much easier for people to choose Windows Phone.”

Yang claimed, however, that Huawei was still committed to Windows Phone devices, but at a lower priority than Android. “We are definitely using a multi OS strategy,” Yang added.

Asustek, however, has reportedly binned plans for a dual-OS device. According to the Wall Street Journal (WSJ), Asustek encountered resistance from both Google and Microsoft, leading the Taiwanese PC firm to indefinitely postpone its dual-OS device plans.

Asustek unveiled its Transformer Book Duet TD300, which converts from a tablet to clamshell-style laptop, in January at the Consumer Electronics Show. The device was due to go on sale in the first half of this year.

According to Patrick Moorhead, an analyst at Moor Insights & Strategy – and quoted by the WSJ –  “Google wants all-Android devices.”

Microsoft is also believed to be unwilling to share space on computers with Google, particularly on business-oriented desktop and laptop PCs, as it might help the search engine giant attack Microsoft’s heartlands.

Asustek is also to stop selling the dual-OS Asus Transformer AiO P1801 and P1802 all-in-one PCs launched last year due to Microsoft’s “new policy” of not supporting dual OS products, according to an internal Asustek memo circulated to some employees and obtained by WSJ.

Samsung announced a dual-OS tablet last year, but that has yet to see commercial light of day.
