my Friend is Using Stock ICS 4.0.4 everytime he makes a call , he always have to toggle noise reduction off to be able to hear him on the other line.. can someone know how to permanently disable it? thanks
You can do this by pressing the menu button while in call status then press the "Noise Reduction Off".
Samsung Galaxy S2 increase microphone volume
- Type this code on your Galaxy S2 dial pad *#*#197328640#*#*
- A number coded menu will then show.
- Now press [5] AUDIO
- Next [1] NB (VOICE CALL)
- Next [1] HANDSET
- Next [1] VOLUME
-Next [1]SRC SPEECH RX Volume
- Then [5]5_lvl: 90 ( the 90 is the input value of the microphone volume level, yours might have a different value than 90. Just remember the default value of yours so that you can use it to revert it back again)
Now, on that window there's a line stated "Input". You are going to edit or change the input value which can be done by pressing the Menu button, then the "Key Input". Write down 110 as your new maximum microphone input level and then press "OK" This is just like adjusting the volume knob of your audio amplifier to maximize the loudness.
