Re: In the UK it isn't on sale yet.
Samsung was reported to have narrowed it down to the battery being used, though it is possible it might be vulneable only in combination with other stuff to do with USB-C or converters. Apparently the ones sold in China are fine, because they used a different battery.
I wonder who made the battery in the Chinese ones, and who made the battery in the rest? It would be extra egg on Samsung's face if they made the dodgy batteries, and the phones sold in China used some Chinese made battery that was fine...
