Speakerphone, Volume +

I have the impression that the sound from the speakerphone is low ( He hears fine interlocutor, but I did not hear him well).
Is there any way volume up and if so what can be the correct settings in this area?

Go to your phone dialer and type: ##3646633##

–>An EngineerMode will appear, swipe left to get to Hardware Testing, tap on Audio and than tap on Normal Mode.

–>Audio_ModeSetting will appear.

–> select [sph]

–>change values:

lvl 6 = 160 (was 136)

lvl 5 = 145 (was 124)

lvl 4 = 125 (was 112)

lvl 3 = 115 (was 100)

lvl 2 = 105 (was 88)

lvl 1 = 90 (was 76)

lvl 0 = 80 (was 64)

–>Repeat the same for [sph2]

Step 2: Almost there
–> Go back to Speech Enhancement

–> change Common Parametre to Normal Mode

–> while there, select parametre 7, and set it to 100.

–> select parametre 6, set to 425.
