Are you having issues with the microphone on your Microsoft Lumia 640 phone? You might need to have it repaired. Problems with your microphone can be a symptom of faulty wires, broken boards, or other internal issues. However, problems with sound could be caused by multiple parts of your phone.
Sometimes when you think you have a microphone problem you actually have a microphone problem. How can you tell the difference? If you are experiencing poor sound quality or you can?t hear anything sound at all, it is probably a microphone problem. If you can hear fine, but others cannot hear you on a call, then it is likely to be a microphone problem.
Your phone has more than one microphone. The internal microphone is what you hear on a phone call. It operates at a lower volume because you have the phone pressed against your ear. The external microphone is what you hear when your phone rings, or you are listening to music. This sound is meant to be louder so that you hear it when it is in your pocket, bag, purse, or across the room.
If you are not receiving any sound from your microphone, then it is probably a hardware problem with the microphone itself. However, if the sound is just distorted or fading in and out, then there could be other causes. Your phone could be having connection problems with your carrier. It could also be a software problem caused by a recently downloaded app. Check with your carrier, and if there is not a connection issue, then you might want to reset your phone. Make sure you backup your data first, as a reset will erase the data you have saved.
