Why does the screen slightly flicker when unlocking the POCO F7 with the fingerprint?
Thank you for your support of Xiaomi products. The phone has been strictly inspected before leaving the factory. Please feel free to use it.
If the screen slightly flickers when unlocking the POCO F7 with fingerprint, please refer to the following reasons:
1. When the fingerprint sensor is activated, the phone will briefly adjust brightness, color profile, or refresh rate, causing a slight flicker;
2. When the brightness is controlled by PWM dimming, it will switch dimming modes rapidly during fingerprint unlock, especially in low-light conditions, creating a noticeable flicker;
3. It is a known bug that the screen slightly flickers when unlocking the screen with fingerprint, which isn’t a hardware malfunction. Please wait patiently for OTA upgrade.
