The Samsung Galaxy S3 has unceremoniously tipped Apple’s once-untouchable iPhone off the top spot as the UK’s most popular smartphone.

Just days after its UK launch the Galaxy S3 has topped the uSwitch Tech’s Mobile Tracker, replacing the white iPhone 4S. See alsoGroup test: What's the best smartphone?

The price-comparison website’s Mobile Tracker ranks handsets based on live searches and sales.

The smartphone war is clearly set between the two main phone makers: Samsung and Apple. The iPhone 4S had only briefly replaced the Samsung Galaxy S2, last month. The Android-powered S2 remains at number 3, despite the arrival of its successor, and there are two other Galaxy handsets (Ace phone and Note "phablet") in the top ten.

Apple’s older iPhone 4 still places in the mobile league table.

uSwitch’s Ernest Doku forecasts that the “one-two punch” of the S2 and S3 augur well for continued strong showings for Samsung in the Mobile Tracker.

“Feeling surprisingly light to carry due to its brushed polycarbonate casing, especially considering the vast 4.8 Super AMOLED screen, the Samsung S III looks set to give the iPhone a serious run for its money,” Doku said when announcing the new smartphone ranking.

Behind the Apple iPhone and Samsung Galaxy handsets is the HTC One Series mobile, three of which appear in the top ten, leaving just Sony hanging on in the Samsung/Apple/HTC smartphone domination.
