First of all I want to tell you that I am rookie in this field [rooting, updating, etc], so please excuse if sometimes I will say some funny things.
I have the feeling that sound of the earpiece is too low [also headset has same problem], even I have the volume for call in set to maximum level. I would like to boost this one. There are a lot of applications in the market, but all of them are able only to increase/boost external speaker.
I understood that there is in the “system” some files with volume setting where you can change parameters for the maximum volume of the call in from 5 to 6, let’s say. I understood that you can damage the earpiece, but I won’t increase with many steps, just one or two. How can I do this ? The phone should be rooted for this operation ?
Or, maybe, is there other “magic” simple solution for this issue?
