Samsung Electronics said on Friday that it planned to unveil a new smartphone based on Google's latest version of the Android operating system at an event in Hong Kong on Oct. 19.

The announcement came after the world's second-biggest handset maker put off the launch of the new device based on the Ice Cream Sandwich system while the world paid tribute to Apple co-founder Steve Jobs, who died last week.

We are unpacking our new Android phone in concurrence with Google, Samsung said in a statement on Friday, without disclosing the name of the new gadget.

Apple and Samsung are engaged in a bruising legal battle that includes more than 20 cases in 10 countries as the two jostle for the top spot in the smartphone and tablet markets. Apple is also the biggest customer of Samsung, buying mainly chips and displays.

Apple's new iPhone 4S finally went on sale in stores around the globe on Friday, with fans snapping up the final gadget unveiled during Jobs' lifetime.

A U.S. judge said on Thursday Samsung's Galaxy tablets infringe Apple iPad patents, but also that Apple has a problem establishing the validity of its patents.
