Samsung is flexing its engineering science muscle with theSamsung Galaxy S II , while HTC and Sony Ericsson are betting on thick Facebook integration andmobile gamingas the war for smartphone supremacy continues at the Mobile World Congress in Barcelona this hebdomad .

Unsurprisingly , this yr ’s show has been all about Android , allot to Carolina Milanesi , inquiry vice United States President at Gartner . With many vendors using the nomadic OS from Google , they must act to differentiate their product with other features .

Samsung kicked off Mobile World Congress with a thrill : The Samsung Galaxy S II is thinner than the Galaxy S , and comes with a dual - core processor , a self-aggrandising , better filmdom and a truehearted net connexion using HSPA+ ( High - Speed Packet Access ) at up to 21 M bps ( bits per secondly ) .

HTC has take a different route with the Salsa and the ChaCha . The two smartphones total with cryptical Facebook integration , including a Facebook release that will light up up whenever there is an chance for user to share contentedness or updates .

“ [ They are ] different , and the fact is what we are go steady on Android is very homogenous . The same goes for Sony Ericsson ’s Xperia Play ; it is something different in a ocean of Android product that all look the same , ” pronounce Geoff Blaber , analyst at CCS Insight .

The Xperia Play has a hazard to sell well if it is priced right , agree to Blaber .

However , today , both Sony Ericsson and HTC lack a high-pitched - closing smartphone with a dual - marrow processor .

“ They are both closely aligned to Qualcomm , and Qualcomm has been , until this show , a little behind Nvidia … but the realness is that we ’ll see those products come later in the year from Sony Ericsson and HTC , ” said Blaber .

The phone number of consumers who really handle whether their smartphone has a dual - meat processor may be in the nonage , though .

“ I intend from a aggregate food market view , consumers are still glad with single - core machine , ” said Milanesi .

LG Electronics is also examine to differentiate with the addition of a 3D screen on the Optimus 3D smartphone . It is one of the most revolutionary products in the mix , but the screen still feel a snatch like a prototype , Milanesi said .

However , the smartphone race at Mobile World Congress is n’t just about the high ending . The backwash to depress the price of smartphones based on Google ’s operating organization also continued , agree to Milanesi .

The most notable launch has been Alcatel ’s , according to Blaber .

The company announced five Android - based phones , all of which will agitate Android into the postpaid market . One phone in particular , the One Touch 890 , which only arrive with 2 G , looks set to take Android below the € 60 ( US$ 80 ) level at retail , with a small amount of subsidy , Blaber said .

ZTE and Huawei also launch low - goal Android phones mean to mine like dominion .

Android is now scale from the very , very low end to high - close smartphones with dual - core processor , hardware quickening and lots of store . The big question is how long the platform can proceed to scale like that ; there is a risk that you begin constraining developers in high - remainder , because they have to accommodate uncomplicated ironware , Blaber said .
