The Mi MIX 3 debuted as the first Mi series device which gets as close as almost 95% screen to body ratio, meaning there is virtually almost no border on the display panel which is the original plan of the Mi MIX series which catapulted Xiaomi to fame years back. But the original Mi MIX and the Mi MIX 2/2S sported a camera at the lower bezel of the phone which is quite a bad idea if you ask me, needing to turn your phone 180 degrees just to take a photo. Now we saw that OPPO Find X did a mechanized slider wherein the rear panel of the phone will slide up whenever you press the camera button, but in Find X, everything is hidden under the slider, be it the front or the rear camera. However, the Mi MIX 3 did a design on its own, having the front camera hidden under the magnetic sliding mechanism wherein you just need to physically pull the screen down whenever taking a selfie. This slider is said to survive a 300,000 slide, probably you wont reach that number in 2 years if you not too much of a selfie person. This time Xiaomi included a dedicated Xiao AI button wherein you can just press the button when you want to talk to your friendly personal assistant.
