No Snark intended..but you need to search the entire thread, that meaning the "Epic 4g Android Development" thread, not just this rom's thread. I can tell you that I remember reading several answers that could help you, where they are, I don't recall...however, have you seen this one? http://turbulentsky.com/samsung-epic...nsumption.html
or this??? http://forum.xda-developers.com/showthread.php?t=770872
also, I know that Kenny and a couple others have posted info about voltage control in this very thread, there are even some screen shots of voltage control in here, probably 15 or so pages back if I recall correctly.
As mentioned, I had some strange issue with the VC, so that confused me a bit. But I was able to download it again and set it the way Kenny previously mentioned, and hopefully it do the trick. If it doesn't, I will try to move on to other possible cures.
Forgive me for being so defensive, I just work in an environment where "tone" is important and am really particular about the way one's "voice" is conveyed via an electronic venue.
Thanks for all of the help.
