How to increase the volume for calls with receiver and speakerphone?

For earpiece in a call

enter *#197328640# like you were making a call.
tap 8 - audio
tap 1 - RCV Config
tap 3 - Call config
tap 3 - RCV Codec Gain
tap 4 - cod_rx
Then enter your selection for the gain by tapping on the number. 4 would be a decent choice.

Then hit the end call key. Reboot your phone and try it out.

If its too loud then try 2 or 3. Not loud enough try 5 or 6 but your receiver speaker may start to distort

NOTE:F.Y.I. the default value for cod_rx for each is 0db.
