Apple in unprecedented attack on Samsung and Google: Marketing chief claims majority of Android users are stuck on 'two year old software' Outburst comes as Samsung prepares to launch latest version of its Galaxy handset tonight Apple's Phil Schiller claims its research shows users are switching from Android to iOS in large numbers Apple's marketing chief Phil Schiller has attacked Google's 'fragmented' Android software and its biggest adopter, Samsung hours before the Korean firm unveils its latest flagship smartphone. The marketing chief's rare attack on a rival comes as Samsung prepares to launch the Galaxy S4 in New York tonight. The two firms are locked in a bitter battle for smartphone domination after Samsung overtook Apple in 2012 in overall sales. The tech giants are also facing off in courts around the world in a series of patent disputes. Phil Schiller, senior vice president of worldwide marketing at Apple. has attacked Google Inc's 'fragmented' Android software and its biggest adopter, Samsung Electronics Samsung will take the wraps off its Galaxy S4, after a broad marketing campaign that has helped drive pre-launch speculation and hype to Apple-like proportions. The launch -- the first time Samsung has chosen to host a global Galaxy debut in the United States -- is deemed critical to propelling Samsung deeper into Apple's home turf. Schiller's remarks also came a day after Android architect Andy Rubin stepped down, after having built the free, open-source software into the platform of choice for mobile phone manufacturers around the world. Samsung had 30.3 percent of the smartphone market in 2012, up from 19 percent a year earlier. Apple's share was 19.1 percent last year, up from 18.8 percent in 2011. However, Schiller said he believes the iPhone offers a better experience. 'Android is often given as a free replacement for a feature phone and the experience isn't as good as an iPhone,' he told the Wall Street Journal. He said one of Androids biggest problems was the amount of time it takes to set up. 'When you take an Android device out of the box, you have to sign up to nine accounts with different vendors to get the experience iOS comes with,' he said. 'They don't work seamlessly together.' Schiller told Reuters that Google's own research showed the vast majority of Android users were stuck on older versions of the software, and that Samsung's new phone itself may debut with a year-old operating system that will need updating. 'With their own data, only 16 percent of Android users are on year-old version of the operating system,' he said. Over 50 percent are still on software that is two-years-old. A really big difference. Schiller said fragmentation, or the host of customized versions of Android in the marketplace, poses a problem for consumers. Is his bark worse than his bite? Apple's Phil Schiller has launched an unprecedented attack of arch rivals Samsung, claiming its users are running out of date software Every version of Android's operating system update has to be tested to ensure a good fit for a multiplicity of handset makers before it can be widely released by the handset makers, which slows updates. That's because some manufacturers, such as Amazon.com Inc, employ heavily customized versions. 'And that extends to the news we are hearing this week that the Samsung Galaxy S4 is being rumored to ship with an OS that is nearly a year old,' he said. Customers will have to wait to get an update. Schiller pointed to multiple research from third parties that showed that people who have iOS devices actually use them more than people who own Android devices, and more than half of iOS users are using the latest version of the software. Apple remains the most valuable technology company today, with a $137.1 billion cash pile, or the equivalent of just under the gross domestic product of Hungary. But Samsung knocked Apple off its perch atop the global smartphone arena in 2012, and continues to chip away at its market share with a combination of aggressive marketing, rapid technology adoption and boundary-pushing designs. That onslaught, coupled with growing uncertainty about whether the U.S. giant can sustain growth in coming years, has contributed to a 30 percent decline in Apple's stock since its September peak. That rapid ascendancy was made possible partly by Android, the software Google Inc launched just a few years ago but is now the world's most-used smartphone platform. IDC expects shipments of Android tablets to exceed those of the iPad in 2013.

'At Apple we know that it's not just enough to have products pumped out in large numbers,' he said. You have to love and use them. There is a lot of data showing a big disparity there. Google declined to comment. Samsung did not respond to a request for comment.
