Some Little Patience

Brain

Open MTK Engineering Menu Can be open by 3 ways

1) Go to dialpad/phone and type * # * # 3646633 # * # *

2)In Launcher MTk Engineering menu will be there

3)Download Mtk engineering menu app from playstore and open it by there

After Opening Navigate to Hardware setting tab, select Audio . The list will show as follow:

1.1. Normal Mode

1.2. Headset Mode

1.3. LoudSpeaker Mode - setting the mode of the loudspeaker (the same Handfree mode?)

1.4. Speech Enhancement

1.5. Debug Info

1.6. Speech Logger (Logging of conversations, most likely).

1.7. Audio logger is an audio logger (software for recording audio) with the ability to quickly search, playback and save.

2. Choose the mode you need.

Normal Mode, (if you want to increase the volume of the speaker and microphone).

The Type drop-down menu lists:

2.1. Sip Tone= Internet call

2.2. Mic=(Microphone Volume)

2.3. Sph=(Speaker Volume)

2.4. Sph2 Unknown

2.5. Sid Unknown

2.6. Media

In Normal Mode:

Level -0 ~ 14 These are the levels that the volume's volume is 0 ~ 255.

Select Type: Media

then lower in the Max Vol. 0 ~ 255 set the volume to 250 and press Set.

Next, choose Vol parameter values ​​for the speaker volume when playing media.

Select Type: Sph

Next, the Level list is the signal levels. That would be understandable - there are 7 levels, and each corresponds to one "click" of the volume rocker that is on the side of the phone. When you get to this conversation with a rocker, you essentially sort through these levels of signals. Those. Level 0 is the most "quiet" position of the rocker, Level 6 - the most "loud".

The value of the volume level for each Level is in the cell Value is (0 ~ 160):

It must be changed. It changes simply - you erase the old value, enter a new value and press the Set button (next to the cell).

Warning! Write down (remember) the factory numbers before changing! If after your manipulations the speaker will wheeze, go back the previous values.

Level 0 - 90 Set

Level 1 - 100 Set

Level 2 - 110 Set

Level 3 - 120 Set

Level 4 - 130 Set

Level 5 - 140 Set

Level 6 - 160 Set

The Max Vol. 0 ~ 160 we have already changed earlier.

Speaking volume: (in microphone) Configure Mic

With the volume control in the microphone everything is much more prosaic. Whichever readings you enter, automatically at all positions of the volume rocker only one will work (the minimum of all preset). Therefore, the readings of Level 0 ~ 14 are the same.

To adjust the microphone volume - select Type: Mic.

Value of the Value parameter for the volume (sensitivity) of the microphone.

Warning! Record the factory numbers before changing!

Level 0 - 64 Set

Level 1 - 112 Set

Level 2 - 192 Set

Level 3 - 152 Set

Level 4 - 192 Set

Level 5 - 220 Set

Level 6 - 220 Set

in last just modify

level 14 to 250 after 6 do not touch them

After that, I was better able to hear.

If, while talking on the phone, your interlocutor complains that he hears his echo, then you have set the microphone sensitivity high, you have to lower them. Example:

Level 0 - 180 Set

Level 1 - 180 Set

Level 2 - 180 Set

Level 3 - 180 Set

Level 4 - 180 Set

Level 5 - 180 Set

Level 6 - 180 Set

Here you can experiment a little. Values ​​can be in the chapels 140 ~~ 250. It all depends on how good a microphone is in the phone. Also, when setting this parameter, the volume of the sound recording depends on the video or voice recording.

Whatever changes take effect on the phone you need to restart

In Every Menu you can Modify and Tweak it your self according to your convenience

Normal Mode will solve all low sound problem but if problem persist go to another menu

Dont Forget to press Thanks Button if you like my thread
