How to fix speaker issues on your Android phone
If your phone is experiencing speaker issues you will need to go through the troubleshooting guide below to identify where the problem is coming from. But first you need to identify the issue. This should be that no sound comes out from the speaker while listening to music, using the speakerphone, playing a game etc.
If you have this issue with your speakers then there are a few things that may have caused this. The headset or other enhancements that your are using may be nonfunctional. A third-party application may cause the speaker to malfunction or the device to be unresponsive, or your device may have experienced some sort of physical or liquid damage. In the later case, the Samsung warranty will not cover the damages.
Troubleshoot speaker issues on Android phones:
To fix the speaker issues on your phone, remove all enhancement accessories and headset from the device and perform a test call. Leave a message on your voicemail. Then check your voice messages and playback the test message. If you can hear the message, you will need to replace the headset.
If the problem isn’t yet fixed, then you have to test the external speakers. For this, make a test video clip with audio or record your voice for a few seconds. Then playback the record on your external speakers. If you can hear the audio then the speakers are fine. If not, you should try to perform a factory data reset.
If the problem is still not resolved, you should get your phone checked in a service center as this may be a hardware issue and you may need to replace the speaker.
