Xiaomi posted an official teardown video of the Xiaomi Mi 9T (aka Redmi K20) showing what makes it tick. The pop-up selfie camera is driven up and down by a stepper motor, a design that should be familiar enough by now.
The rear camera has two modules – the 48MP main cam and the telephoto cam come as a unit, the ultra wide-angle camera is on a separate module. The complicated-looking motherboard wraps around all that. It houses the Snapdragon 730 chipset and memory, plus the heat spreader.
Can you guess how the #Mi9T s pop-up camera really works? 🔁 if you’re correct….
