No sound or poor call quality when making or answering voice calls using the HUAWEI kids watch

Problem

When using the kids watch to answer or make a voice call (), the user cannot hear the other party's voice, the other party cannot hear the user's voice, or there are issues such as cracking sounds, noise, or volume fluctuations.

Solution

1. Check the network connection of the watch or the device you're calling.
   • If the network connection of your watch or the device you're calling is poor, for example, if the watch or phone has less than three bars of signal () or no Internet connection (), this can cause no sound or poor call quality.
   • Move to an area with a good signal such as an outdoor area or a balcony and then try again. If the signal strength remains the same, remove and reinsert the SIM card and restart the device. If you still can't get a network connection, the nearby base station or SIM card service may be faulty. In this case, contact your carrier for assistance.
2. Adjust the call volume and quality on the watch.
   • On the call screen, tap the speaker () icon at the top. Then, tap the + icon to increase the call volume.
   • Keep the watch relatively still during a call. Do not swing your arm, rotate your wrist, remove or rub the watch strap, run, or rub the watch against clothing, such as sleeves. This ensures that the microphone picks up your voice clearly and the call quality is good.
   • During a call, raise your wrist to keep the watch about 10 cm away from your mouth. This ensures a louder and clearer sound for the other party. If you lower your arm, the distance between the watch and your mouth may exceed 30 cm, and the sound picked up by the watch's microphone will be relatively low.
     

     Usually, when you activate the ringback tone feature, the volume of the ringback tone is louder than the beep sound you hear while waiting for a call to connect. This is normal. Please hold the device close to your ear during the call.

3. Check whether the speaker or microphone hole of the watch is blocked by foreign objects.

   Hold the watch with the microphone or speaker hole facing downward. Use a clean soft brush to remove any dust. Then try again.

   • If you are using a HUAWEI WATCH KIDS 4 Series or later model, and the speaker or microphone hole is dirty, you can wash the hole with clean water at room temperature. Then enable the drainage feature and air-dry the watch completely. (To use the drainage feature, press the button (HOME button) on the watch, go to Settings > Drain water, and follow the onscreen instructions.)
   • When wearing the watch, avoid getting substances like shower gel, shampoo, cola, or milk into the speaker hole. If these substances enter the hole and are not cleaned, they can block the speaker hole and cause issues such as no sound, low volume, or noise during calls.

If the issue persists

If the issue persists, the watch hardware may be faulty. In this case, send your watch photos and documents to the HUAWEI FamCare app via chat, and take your watch and proof of purchase to an authorized Huawei Customer Service Center for assistance.
