Other said that portions of Ice Cream Sandwich and the Nexus Prime may not be ready to be shown off, or various parties, such as Verzon Wireless, to be included in the announcement were not ready for the event.

A Google official, who asked not to be named, told Computerworld on Monday that the delay was "not due to any technical reasons."

"Google doesn't spend much on marketing and maybe parties to the news weren't on the same page," Enderle said, adding that "Google has inexperience running marketing groups."

Jack Gold said the delay shows how the competition between Android and iPhone has intensified. Even if Jobs hadn't died, introducing another Android phone a week after the iPhone 4S unveiling would have been difficult, they said.

"Timing is everything in announcements and the timing wasn't right" for Samsung and Google, said Jack Gold, an analyst at J. Gold Associates. "Could there be come issues with Ice Cream Sandwich? Yes,it's possible, but that usually hasn't stopped Google before when they announced something and then fixed the problem before the release."
