Troubleshooting cell phone speaker problems
There are cases where you may think you have issues with your speaker, instead it with your microphone. So what’s the difference between a microphone and speaker problem? If you’re experiencing poor sound quality or you cannot hear any sound, then it’s a speaker problem. However, if you can hear, and others can’t hear you on a call, then you would have issues with your microphone; either way you’ll need phone repair services.
Your phone contains more than one speaker; the internal speaker is what you hear while on a phone call. It has a lower volume as you have the phone pressed against your ear. The external speaker, on the other hand, is what you hear when the phone rings or are listening to music.
The external speaker is louder to help you hear a call when the phone is in your pocket, across the room or purse. If you don’t have any sound from the speaker, it could be a hardware problem which will require a speaker repair. If you have a sound that is fading in and out or distorted sound, then you be having issues with your carrier. It can also be a software problem due to recently downloaded apps.
