A reader passing the Oxford Street branch of Phones 4U has just sent in the below photos of the store’s main window, which is teasing a new Samsung arrival for later this month. The flagship shop, which exclusively sold the Galaxy Nexus at launch, currently features a massive “SAMSUNG” logo along with the date 30/03/2012.

It’d be rather silly of the retailer to tease the Galaxy Pocket‘s launch in such a manner, so this is surely the first sign of something big coming from Samsung. The Galaxy S III, for example? But isn’t it too soon for that?

It would be rather unusual for a retailer to waste its time promoting a mere announcement date, so we’d have to assume it’ll have something new by Samsung to sell on that date. But what?

Better not just be another type of Galaxy Tab.

Thanks to reader Guy for the snaps.
