Noise when talking on the phone: why and how to fix it

There are problems that have very specific causes and solutions. In some cases, there can be a huge number of reasons.

When it comes to the poor hearing of a person during a conversation, there are several main factors that we will talk about. The most obvious is speaker damage. This can happen as a result of the device being dropped, water ingress. Try switching to an external speaker, if the problem is gone, then the conversational speaker is to blame.

VoLTE is a technology for transmitting voice over an LTE network. The original idea was to improve the sound quality during a telephone conversation. However, this can play out in the opposite direction. Try going to the smartphone settings and in the communication section disable the use of VoLTE, then restart the smartphone. It is likely that audibility during calls may improve. You can also test the microphone and speaker yourself by recording messages on the built-in voice recorder and listening to it.

Another factor is an unstable connection. It is likely that your location has a congested network or simply a weak signal. Try to use a WhatsApp or Telegram call instead of a regular call, if possible. Some “sound enhancement” or call recording programs can intercept data and degrade the quality of communication, add noise. Well, if nothing helps, then the last resort is to contact the service center.
