Samsung has announced a press event on Oct. 11, exactly a week after Apple's Let's talk iPhone program on Oct. 4. It is expected that Nexus Prime, the flagship smartphone for the Google Android platform, will be officially presented at the Samsung event.

Samsung Nexus Prime will be the first smartphone with an Android 4.0 operating system, codenamed Ice Cream Sandwich, which is designed to provide strong competition to Apple's expected iPhone 5.

iPhone 5 is expected to run on the latest iOS 5, which will be coming with 200 new features, including an improved notifications system, a Newsstand and iMessage. In addition to this, iPhone 5 is expected to feature the new iCloud service in operating iTunes for wireless remote access of music from all computers and mobile devices.

Ice Cream Sandwich is expected to take cues from existing Android OS versions Honeycomb (for tablets) and Gingerbread (for phones).

Nexus Prime is expected to feature a 1.5-GHz dual-core processor, a 4.5-inch screen and have 720p (1280 by 768) video resolution.

The possible unveiling of Nexus Prime and Ice Cream Sandwich, in addition to Apple's expected unveiling of the iPhone 5, is going to make October the biggest month for smartphones this year.

It is highly possible that Samsung's new Nexus will arrive in stores next month or early November, to compete against Apple's new iPhone.
