( CNN ) -- A day after reports that Samsung plans to announce a follow up to its popular Samsung Galaxy S III smartphone in February , the Korean company has taken to Twitter to deny them . The Samsung Galaxy S4 , a new iteration of the phone that has established itself as the chief rival to Apple 's iPhone , will be introduced in February at the Mobile World Congress in Barcelona , Spain , according to The Korea Times . A day after that report surfaced , though , Samsung took to its Korean Twitter account to deny it . `` Please note that some media reported speculation that the Galaxy S 's subsequent models will be released , '' the tweet read in Korean , calling the report `` a simple rumor [ that ] is not true . '' The report from the Times , the oldest English-language newspaper in South Korea , cites unnamed company officials and parts suppliers in the region . Among the Galaxy S4 's features will be a 5-inch screen , slightly larger than the display on the popular Galaxy S III and a full inch bigger than the iPhone 5 , the report said . It will have more powerful hardware and software and will `` definitely use '' 4G LTE networks , a parts supplier told the paper . The perils of sleeping with your mobile phone . Phones running Google 's Android operating system have been outselling the iPhone for some time . But that 's a fragmented field that includes dozens of phones of varying quality . No single handset has established itself as a serious rival to Apple 's phone . The Galaxy S III has made perhaps the best claim . Last month , the company announced it had sold more than 20 million units in three months , making September the first month since the release of the iPhone 4S that it was n't the world 's top-selling smartphone . Snap reviews of the iPhone 5 have been somewhat mixed , at least among the tech media . Many who got a hands-on demo at Apple 's Wednesday announcement praised its slimmer , lighter design , bigger display and faster processor . Others said the device failed to produce groundbreaking advances at a moment when Apple , perhaps for the first time ever , finds itself needing to catch up with features available on other phones . Customer response , however , has been overwhelming . Pre-orders of the iPhone 5 `` sold out '' almost instantly ( an admittedly arbitrary feat considering Apple controls the supply ) , with orders topping 2 million in the first 24 hours . That 's double the 1 million for last year 's iPhone 4S in the same time period . The phone hits stores Friday in the United States , Australia , Canada , France , Germany , Hong Kong , Japan , Singapore and the United Kingdom . It rolls out in 22 other countries on September 28 . The S4 's release would mark Samsung 's biggest salvo since a federal court in California ruled that Samsung violated multiple Apple patents in the release of its own products . After the ruling , Apple asked the court to add the Galaxy S III to the list of products that are in violation . The case was just one of roughly 50 patent disputes in different countries . Some of the other courts have ruled in favor of Samsung . According to the South Korean news report , Samsung is working with U.S. carriers on modified designs the company said will eliminate any questions about patents . The report said Samsung plans to fire back in another way , too . Samsung is asking Apple to pay more for the processors it produces at an Austin , Texas , plant and is promoting itself as `` the only firm that can guarantee on-time delivery , output commitment and better pricing for mobile application processors , '' one executive told The Korea Times .
