Review HMD's efforts to put the Nokia brand over what we call the "Shenzhen generics" formula haven't exactly set the world on fire yet. But in all honesty, you'll struggle to find anything better for £399, the revised price of the Nokia 8.

China's supply chains and market maturation have caused a great levelling in the phone industry. For about two or three years, you've been able to get a top-specced phone from a no-name brand - and what additional features Samsung or Sony offered didn't really matter to most people. Models from Xiaomi, Oppo and ZTE repackaged quality components but otherwise indistinguishable. They were largely generic. And made in or around "Shenzhen". Hence "Shenzhen generics".
