After the last firmware update the sound was pretty low,so i wanted to increase the volume... tried the volume hack but it did not increase the headphone volume,only the handset volume..... this is kinda a hardware fix...
Do this at your own risk
first close musi app
then open dailer an type :
*#197328640#*
this will open service mode
here click [8] audio
then click [2] headset
then click [2] rx value
then click [5] rx codec for midi
then click [1] rx codec gain:
then pres menu key, key input,and type in 5fff , this increases the gain to about 4db,wich is in my opinion the best option
after u inputed the value pres menu key and select end.
no restart needed,just open music player and press play and you will see the differences
I was about to sell my i7500 because of lack of headphone volume but now im happy...
i think this will work with i5700 and moment,haven;t tried it though!
Sorry bout my english!
