Xiaomi has announced the Mi Mix 3, the latest entry in its series of full-screen flagship phones. It’s yet another high-end Chinese device with a huge screen-to-body ratio achieved by hiding the front-facing cameras on a sliding mechanism — no notch required. Unlike the Vivo Nex or Oppo Find X, however, the slider isn’t powered by motors. CEO Lei Jun compares the design to older sliding phones and suggests that it’ll be relaxing just to play with.

The previous two Mi Mix phones were both pioneering attempts by Xiaomi to reduce the bezels around the screen as much as possible, but they predated the now-ubiquitous notch and compromised by awkwardly placing the selfie camera below the screen, forcing you to hold the phone upside-down or deal with an unflattering angle. Even Xiaomi itself adopted the notch earlier this year with the Mi 8. But the Mi Mix 3 preserves the spirit of the series while seemingly fixing one of its bigger flaws.
