S500i low volume in calls

[Loz]

Was the Volume alright before the Upgrade, if not it might be your Ear speaker going? if not try when having a call try the Volume button to see if that increases the Volume.

i have the phone for a week, since I bought it the volume in call was low, the volume is set at max for calls...

i tried some acoustics but no effect
is there any program to edit acoustics , to increse the volume for calls very high and see if there is any change or the speaker/mainboard has problems
