I've noticed that on the G4 and my M8, Gsam would report charging as a negative current discharging as a positive current. On my Note 3, it reads as expected, with charging as a positive current. I tried emailing the developer a while back but never got a response. Is there any way to change it so it reads correctly? The amount of current seems to read right, it's just reversed. See attached screenshots to see how it's showing on my G4.
