Why is the hover angle of the Xiaomi MIX Flip abnormal?

In order to better experience the screen hovering function, you can refer to the following usage tips:
1. The product can hover at 45° to 120° within 12 hours of folding. Due to the influence of various factors such as the use environment, usage time, product production batch, etc., the hovering angle of different devices varies slightly, which is normal. After the product is unpacked for the first time, please keep the phone folded for more than 12 hours to better experience the hovering function;
2. If the product has been folded and placed for a long time and rebounds when hovering, please flatten the screen for 5 minutes, or unfold the screen several times and keep it flat for several seconds, and then experience the screen hovering function;
3. If the product has been unfolded and placed for a long time and rebounds when hovering, please fold the screen completely for 5 minutes, or fold and unfold the screen slowly several times, and then experience the screen hovering function.
Hovering rebound is a mechanical property caused by the large bending stress (elasticity) of the screen due to the long-term expansion or folding of the screen. The above method can quickly release stress and resume use. This phenomenon does not actually affect the durability and reliability of the product.
