Samsung announced its first Windows Phone 8 (WP8) run smartphone ATIV at the IFA event in Berlin. Nokia followed suits with its announcement of the Lumia 920 and Lumia 820 smartphones, which will also boast the new operating system. However, The Verge reports that the WP8 software is still being developed.

"Delays and bugs during testing have pushed back the launch, and associated devices, by weeks. We're told that HTC in particular has had a tough time testing one of its Windows Phone 8 devices, a process that has impacted its ability to announce handsets as early as Samsung and Nokia," indicates The Verge.

The Verge suggests that Microsoft had initially planned the launch of the WP8 in early October; however, the event is not expected until Oct. 29. The Verge further reports that Microsoft has been working closely with U.S. carriers to ensure that the testing period for the WP8 is reduced.

Delays in final carrier testing may have a domino effect on the availability of the much-awaited WP8 devices. Smartphone makers will need the final version of WP8 before they can start supplying the devices. Moreover, the smartphone manufacturers will want to show consumers how the new operating system performs on their latest devices.

At the launch of Nokia's Lumia 920 and Lumia 820, the guests were "prevented from playing with the Windows Phone 8 operating system," claims The Verge. Furthermore, the report suggests that Microsoft "instructed Samsung, Nokia, and HTC not to show off the operating system."

Time will tell if Microsoft is on track to launch the latest Windows Phone 8. However, smartphone enthusiasts will be eagerly waiting to lay their hands on devices that run on the latest OS.
