Problem:

There are noises when the user plays audio or video using the speaker on their HUAWEI phone/tablet.

Solution:

There are several reasons that may result in this issue occurring. Open the My HUAWEI app on the home screen, log in to your HUAWEI ID, and perform the hardware test as follows: Go to Support > Smart Diagnosis > Other hardware damage > No sound or noises > Sound test. Follow the onscreen instructions to test the receiver and speaker.

• If any error is detected, back up your data and take your device and proof of purchase to an authorised Huawei Customer Service Centre for assistance.
• If no error is detected or no test item is available, power off and restart your device and try again. If the issue persists, try the following methods:

1. Check the playback source and app

Play other audio or video files and check whether the noises still exist. If not, the quality of the original audio or video file may be poor. It is recommended that you download other resources and play them. You can also use another music or video app to check whether the issue is caused by the app.

2. Close background apps or cool down the device

Running too many apps in the background for a long time may consume system resources, which will cause the device to heat up and slow down playback. Close background apps and wait until the temperature returns to normal. Then check whether the noises disappear.

3. Check for system updates

Update your phone/tablet to the latest system version by going to Settings > Software update/System update, and check whether the issue is resolved after the update.

4. Eliminate interference

High-magnetic-field equipment (such as an induction oven or microwave oven) may interfere with the playback on your HUAWEI phone/tablet, resulting in noises. Keep your device away from the equipment or environments that may cause interference. Move to another place and try again to check whether the noises disappear.

5. Check whether the speaker is faulty

Insert a headset and try again. If the playback is normal, the speaker may be faulty. In this case, restart your device or play other files.

6. Check whether the speaker dust filter is blocked

Make sure that the device is covered by a matching protective case to prevent the speaker holes from being blocked. If your device is exposed to water, beverage, oil, dust, or other substances, its filter will be blocked and the speaker volume will be low after long-term use. Use a toothbrush or a soft brush dipped in alcohol to gently clean the dust filter through the speaker holes and check whether the playback is normal.

• You can also take your device to an authorised Huawei Customer Service Centre for a thorough cleaning.

If the issue persists, back up your data and take your device and proof of purchase to an authorised Huawei Customer Service Centre for assistance.
