Along with a centrally located Oxford Street shop, this was Samsung’s biggest — and thus most expensive and ostentatious — exhibition space in London. Samsung made a big point of promoting its Experience Stores, making them the destination to get the very first Galaxy S4 and, later, S5 units sold in the UK, but excitement and sales have apparently petered out after a strong start.

Drop in profits seem to be hitting Samsung hard.
