Volume gain, issue related with the screen

---

With code (*#0002*28346#) i have modified the values of "music 4p earphone"
(i only want to gain volume of the music trough the headset).
What i modified: (i try everything and this values produce a considerable
valume gain and also the sound quality has no decrease)

MAX 9877
1.Speaker Volume Control (01h)
SPKVOL4-0 "00000"
2.Left Headphone Volume Control (02h)
HPLVOL4-0 "11100" (ORIGINAL VALUE: "10111")
3.Right Headphone Volume Control (03h)
HPRVOL4-0 "11100" (ORIGINAL VALUE: "10111")

The problem is when i listen some music with these values and i lock
the screen or blank the screen (in nitrogen player),
the screen turns on again by itself.

If i restore to the original values there is no problem with the screen.

Please can anyone help me?

i did the same setting and so far i have never encountered issue like yours.

perhaps you tinkered with other setting.

Thanks for your answer, i found that this only happen when i use the handsfree earphones. When you connect slowly the handsfree (the one that cames original) the device show a list in one you can chose with or withou microphone headphones. if i choose without mic the problem is gone, but of course the microphone doesnt work!

Please try to put this values and play a loudly song.

3.Right Headphone Volume Control (03h)

Edit: These are the best values to gain the volume up without decreasing the sound quality.
