The Xiaomi Mix comes as a very fragile device, not only at the rear ceramic glass covering it adorns, but also at the front considering it is a very wide device with a 6.88-inch display. That makes the device easy to get cracked whenever it falls down.
According to the unfortunate Xiaomi Mix owner, the device fell from the sofa to a tiled floor, just an height of 50 cm but that was enough to fragment the top left edge of the display. The owner also hinted during interaction that the cost of repairs for the device amounted to 1350 Yuan ($196). That is because the Xiaomi Mix comes with a premium custom display which costs a lot higher than the normal displays on other phones.
So it is strongly advised that in case you own an Mi Mix, get it insured for just 249 Yuan per year. It saves you the cost of repairs if the screen gets broken as well as if it falls in water for a duration of 12 months.
