No Comments

  1. In the phone dialer type in *#*#197328640#*#*
  2. A menu should now be shown. In the menu, press  [5] AUDIO
  3. …then [1] NB (VOICE CALL)
  4. …then [1] HANDSET
  5. …then [1] VOLUME
  6. …then [1]SRC SPEECH RX Volume
  7. …then [5]5_lvl: 88 (note that you might have another value than 88 on your handset. Write down this value in case you want to revert to it later)
  8. The window that is now shown should have a line saying “Input?”. To input a new value press the menu button, then “Key Input”. Write 110 as the new value and press “OK“.
  9. You have now adjusted the microphone volume when noise reduction is disabled, and it is time to do the same when noise reduction is turned on.
  10. Press the menu button, and then “Back”. Do this four times in total, until you get back to the menu that the text “NB (Voice Call)” in the first row.
  11. Now, press [7] HANDSET(2MIC) and repeat steps 5 to 8 listed above.

I have had no complaints about the microphone volume after I completed these instructions. Hopefully it applies to you as well! The only downside with this trick is that it won’t survive a restart of the phone
