If this issue occurs when playing music or video:
Your device’s audio may be poor because of a poor network connection. Enable Airplane mode for a few minutes, then disable it and check your network connection again. Alternatively, move to a location with a better network connection.
Open the camera on your device and record a video. Open and play the recorded video.
If the sound is normal when playing back the video, it means the speaker of your device is working normally.
Try to reset or update your device. (Refer to “How can I perform a factory reset on my device in the Back Up & Reset module” & “How can I upgrade my device in the Basic Settings module”).
If the previously described options do not help, you can contact our hotline or repair center to get more professional technical assistance. Find the hotline or repair center information from the official website or “Support Center” APP.
Note: Available settings and menus may vary depending on device model and software version.
