There have been quite a number of complaints we got through our mailbag, from owners of Samsung Galaxy S4 regarding some speaker and microphone issues they have encountered while using their device. Some say they cannot hear anyone from the other end but they can hear them. Some are talking about hearing no sound coming out of the speaker when they try to use the speaker phone, playing a game, listening to music or watching a video.
TROUBLESHOOTING SPEAKER PROBLEMS
The problem about no one can hear you on the other end while on call may likely be due to some microphone issues with the device. But if it is you who cannot hear anyone but they can hear you, then that could be an indication of some speaker problems with the device.
POSSIBLE CAUSES OF SPEAKER PROBLEMS
Speaker problems with the Galaxy S4 are likely caused by using a headset or some other kind of nonfunctional enhancements. In some cases, the problem is due to a third-party application that is making the device unresponsive to certain commands. And lastly, the device could be experiencing some type of liquid or physical damage.
Here are the things you can do as primary resolution to speaker problems with the GS4. They are as follow:
Try to remove all enhancements or paraphernalia attached to your device including a headset.
After removing all connected enhancements from your device, place a test call to your Voicemail.
Try to playback the Voicemail on your device and see if the issue is resolved. Otherwise, you have to consider replacing the headset to get the problem solved.
If the speaker problems persist, then try doing some further tests to know what really is causing the problem and have it completely resolved:
A. Perform external speaker test. Here is how to do it:
Record a clip for a few seconds with audio using the voice recorder or camcorder application on your device.
Playback the clip.
If you notice the audio is clear through the external speaker, then it denotes that the device is working fine.
In case you notice the audio is not clear, or hear no sound while playing the video clip, then you may need to do a Factory Data Reset on your device.
NOTE: Factory data reset here means that you are going to reset the device to factory defaults.
B. Perform Earpiece Test. Here is how to do it:
Try to place a test call to your Voicemail.
If you hear the audio clearly through the Earpiece, then that indicates that the device is functioning well.
But in case you notice the audio is not clear or no sound is heard at all, proceed to Factory Data Reset.
If speaker problems persist, then try to uninstall applications. It could be that an application is causing the device speaker to become dysfunctional.
TROUBLESHOOTING MICROPHONE PROBLEMS
An indication of a potential microphone problem on the GS4 is when you can hear callers but they cannot hear you on their end.
In case you are detecting possible microphone issues with your device, try doing these:
Remove the battery for 30 seconds, with the device still powered on. Wait until the time has elapsed, then replace the battery.
Turn the device ON.
Record a clip for a few seconds with audio using the voice recorder or camcorder application.
Playback the clip to test audio.
If you hear the audio is clear, then it simply means that both the device Microphone and Speaker are working properly.
In case you notice the audio is not clear or you hear no sound at all, then continue to Factory Data Reset. Doing so will reset the device to factory defaults.
If by all means problems on both speaker and microphone with the Galaxy S4 still continue, then try calling Samsung technical department for further troubleshooting steps. You may also consider repair options as such with the warranty repair, out of warranty repair and Insurance options with the OEM.
