After a long wait, Huawei‘s first foldable flagship Mate X went on its first sale on November 15 and reports indicate the device was sold out in minutes. The Mate X isn’t a cheap phone as it comes with a steep 16,999 Yuan (~$2,420) price tag. Not only is the phone itself an expensive model, replacing the screen if it gets damaged will cost you a fortune (up to 7,080 yuan ($1,007). It has now emerged that the Mate X may not be a very durable model after all. 
This bit was gathered from the warning that was printed on the Mate X’s retail box. Among the series of notes on the box, one is quite eye-catching. It reads that the phone should not be folded in low-temperature environments below -5 degree Celsius. Now, we understand the foldable display technology is a very delicate one and that makes the Mate X a very fragile phone. Moreso, it uses an out-folding screen design which is the ideal definition of a foldable screen phone but it offers zero protection to the screen. The Galaxy Fold deploys an in-folding design.

Why this warning sounds strange is that it is winter season in some parts of the world already, including China, and the temperature gets below -5 degree Celsius. But the reason for this warning may not be far from the fact that the display may stretch when it is folded and under such extremely cold weather condition, it may have shrunk under the principle of thermal expansion and contraction. Thus, the screen may get damaged if there is an attempt to fold it under such low temperature.
Clearly, Huawei still has some work to do with the Mate x. Hopefully, the device won’t go the way of the Galaxy Fold. That’s perhaps why the company is taking a careful approach to releasing the phone.
