What to do if there is a noise during real-time conversation with the Xiaomi Smart Doorbell 3S?

For this issue, you can troubleshoot by referring to the following methods:
1. Check whether the microphone hole of the doorbell is covered or whether there are any foreign objects in the microphone hole;
2. Check if the network signal is good. A weak or unstable Wi-Fi signal will cause the audio quality to deteriorate and produce noises;
3. It is recommended to keep the mobile phone away from the doorbell (avoid screaming) and avoid installing the doorbell next to electronic devices such as electronic door locks.
