Xiaomi launches Mi Mix 4

The Xiaomi Mi Mix 4 is the latest flagship from the Chinese tech giant, but it’s more than that: it also features the debut of Xiaomi’s under-display camera tech, with a hidden selfie camera that – in theory – doesn’t obscure the screen.

This is the follow-up to 2018’s Mi Mix 3, and a lot has changed in three years for Xiaomi. It launched alongside the Mi Pad 5 at a big event in China, but sadly it sounds like it won’t be launching globally, or at least in the UK.

The Mi Mix line is Xiaomi’s attempt to create all-screen phones – that is, devices where the display isn’t broken up by a big notch or bezel, and doesn’t have a cut-out for the camera either. The Mix 3 had a pop-up segment hiding the front-facing camera, but the Mi Mix 4 does something different.

The table below summarises the specifications of the Xiaomi Mi Mix 4.
