Although the Samsung Galaxy S5 is overall a capable device, there is one small issue in the phone that has been present every since the phone was officially released. The microphone gain on the phone isn’t as good as it should be, this results in frustration specially if you are on call in a busy area like a tube, bus station or basically anywhere that has crowd. Lucky for the Galaxy S5 owners, everything on Android has a fix and so does this microphone gain issue.

Thanks to a very talented XDA user who goes by the name thejester123 we have a mod that will increase the microphone gain to a respectable amount in order to help you people. If you are too concerned about flashing the mod, just know that the mod will only make changes to mixer_paths.xml and nothing else.
