How To Fix Low Incoming Call Volume On Your Android Phone / Gadget


So I’m presently working on a review for the THL W6, a 5’3 inch  Android ICS gadget from the stables of Technology Happy Life, China (Mainland) and one of the issues I ran into was the excruciatingly low volumes experienced when receiving calls even in Loudspeaker mode. At a point I felt like one of those ratchet people that literally scream when answering their calls.

Considering that the phone isn’t rooted and the most popular volume boost app for Android (Volume +) is only guaranteed to work on Android Gingerbread devices, I decided to look for alternative means for non rooted phones and thus stumbled on something called Android Engineer Mode.

In Engineering mode, you can access hidden menus which affect the way your battery, audio, touchscreen and etc work.


  1. The wrong configuration could make your device go crazy so tread with caution
  2. As far as I know, this works with phones and tablets that run the virtually unadulterated version of the Android OS such as the THL W6 and Pliris Blaze + amongst others.
  3. I only tested this on Android ICS 4.0.3 and Android ICS 4.0.4.


Dial *#*#3646633#*#* to bring up the Engineer Mode menu

Go to Audio and click on Speech Enhancement

Under Speech Enhancement set the first field to Normal Mode, the second to Parameter 7 and under value set a number between 96 and 128 and then hit Set

Do please make sure to reduce the speaker volume on your device after this hack so as not to blow your phone’s speaker.

That’s all folks. Enjoy and do please leave a comment if it works for you or not and if it doesn’t keep Googling till you find a fix. Winking smile
