Why does the screen brightness of the POCO X7 Pro change when unlocking with the fingerprint in dark environments?

Thank you for supporting Xiaomi products. The phone undergoes rigorous professional inspection before leaving the factory to ensure its quality.
If there are screen brightness changes of the POCO X7 Pro when unlocking with fingerprint in a dark environment, please refer to the following details:
1. When you use the fingerprint unlock feature, the camera increases the exposure to brighten the dark scenes, which also enhances details and colors that were not obvious, resulting in a different effect from what we see with the naked eye;
2. This is a normal phenomenon related to how the screen and sensor work together in low-light conditions. This does not affect the performance or quality of the device, and you can use it with confidence.
