Samsung has unveiled its new, upgraded tablet PC to beat Apple's iPad mini, ahead of its release of the new Galaxy S smartphone next month.
The Galaxy Note 8.0 was officially launched at the 2013 Mobile World Conference held in Barcelona, a statement said.
The model 8-inch display with a resolution of 1280 by 800 features a pixel density of 320 ppi, higher than the 149 ppi of the Galazy Note 10.1.
It features a 1.6 GHz quad-core processor, running on 4.1.2 Jelly Bean, and the latest version of Android operating system (OS), reported Xinhua.
Meanwhile, the Galaxy S IV model, which is expected to be released on March 14 (March 15 NZT) in New York, will heat up competition in the crucial US mobile phone market, where Apple surpassed Samsung as the top mobile phone seller for the first time in the fourth quarter of 2012.
It will be the first US launch of Samsung's flagship Galaxy smartphone in three years, company spokeswoman Chenny Kim said, and comes amid a Samsung advertising blitz in the US that has including light-hearted jabs at Apple fans.
"We introduced the Galaxy S III in London last year, and this time we changed the venue ... as we were bombarded with requests from US mobile carriers to unveil the Galaxy S IV in the country," Samsung mobile division chief JK Shin was quoted as saying on news site Edaily.
The new Galaxy S model is expected to feature a higher-resolution display and camera than its predecessor, as well as a faster quad-core processor, media reports said.
Samsung unveiled its first Galaxy S at the CTIA mobile trade show in the US in 2010, followed by the Galaxy S II at the MWC fair in Spain in 2011 and the Galaxy S III in London last year.
Samsung may have lost its lead in the US handset market but globally the $US210 billion South Korean company is expected to widen its smartphone advantage over Apple this year, helped by a broad product line-up.
Apple investors have grown anxious about the company's prospects amid intense competition from Samsung's cheaper, Android-powered phones, and signs the premium smartphone market may be close to saturation in developed markets.
Apple shares have slumped 15% this year and the company is reportedly slashing orders for screens and other components from its Asian supplier as intensifying competition erodes demand for its latest iPhone.
