Why does the screen color of the Redmi Note 14 Pro 5G change when unlocking with fingerprint in dark environments?

Thank you for your support of the Redmi product. The phone has been inspected strictly before leaving the factory, so you can rest assured of use.
If there is a color change on the screen of the Redmi Note 14 Pro 5G when unlocking with fingerprint in dark environment, please refer to the following details:
1. OLED screens light up individual pixels rather than using a backlight. When unlocking, the pixels around the fingerprint sensor or across the screen may activate or adjust slightly, leading to subtle color shifts;
2. When using fingerprint unlocking in a darker environment, as the brightness of the fingerprint icon is relatively high, it will have a slight impact on the brightness and color of the screen. This is a normal phenomenon and you can use it without worry.
