Why does the high-speed QR code scanning function of the POCO F7 Ultra occasionally fail?

The POCO F7 Ultra has undergone strict professional inspection before leaving the factory, so you can feel free about the performance and reliability of your device.
The QR code scanning function is only effective on the Home screen. At present, there is a probability that it will be recognized as a non-Home screen scene. Please wait patiently for the subsequent version update.
