Samsung and Phones4U have just announced that a large section of the phone retailer's flagship store on Oxford Street in London will be converted into a Samsung-branded substore. We're told the mezzanine area and a big chunk of the ground floor will be committed exclusively to Samsung gear, showing off that company's vast range of Android handsets, its AllShare wireless streaming tech, and other products. The new store is set to open its doors tomorrow, March 30th, and was teased last week with new insignia on the windows outside. Many believed that teaser related to the launch of a new Samsung smartphone — we all know which one we've been waiting for — but as it turns out, it was a precursor to today's announcement. In any case, if you want the best spot to experience the full Samsung Mobile experience in all its splendor, this new central London store will be the place to go.
