Why does the sound in the earphones occasionally lag when flipping the cover on the Xiaomi MIX Flip under playing videos in the background?

Thank you for using Xiaomi products. If you notice the sound lag in your earphones when flipping the cover of your Xiaomi MIX Flip while playing a video, it is related to changes in the device’s Bluetooth connection.
For your reference, the detailed explanations and recommendations are as follows:
1. Flipping the cover of the Xiaomi MIX Flip alters the antenna angle, which can affect the Bluetooth signal between the device and your earphones. This change can occasionally disrupt the data transmission, leading to sound latency or lag during video playback;
2. Try adjusting the orientation of your phone or the angle at which you are using it. This can help realign the antenna and improve the Bluetooth signal strength, reducing the likelihood of sound lag.
