Why do some spots appear when the POCO C71 is dropped on the ground?

The screen of the POCO C71 is fragile, and like most smartphones, it can be vulnerable to external impacts.
For your reference, here are more details of the issue:
1. When the phone is dropped, there is a certain chance that the screen will be directly impacted, which will cause spots, discoloration, or other display issues. This kind of damage occurs when the screen is subjected to pressure or shock from a fall;
2. To minimize the risk of screen damage, we highly recommend using a protective case for the phone. A well-designed case not only offers a layer of protection but also extends slightly above the screen, helping to absorb shocks and reduce the impact on the screen when the phone is accidentally dropped, thereby preventing or minimizing adverse effects on the display.
