The Huawei Mate 20 X is the largest of the Mate 20 Series of handsets. I really liked the Mate 20 Pro, and my US colleague Matthew Miller took a shine to the Mate 20. The Mate 20 X shares some top-end specifications with these two handsets, combining them with a massive 7.2-inch screen. It costs £799 (inc. VAT), undercutting the Mate 20 Pro by £100.
