Well everybody, as it has been asked many times now so i bring you the guide to increase the ""Microphone Gain"" on lollipop.

You will need to make some changes to the mixer_paths.xml content located in system/etc.

Open in Notepad++ or editor of choice and search for <path name="rec-main-mic">.

See below for what to edit,be careful not to adjust more than the value stated.

Save and set permissions to 644 or rw-r-r then reboot.
