After trying countless mm roms,couldn't get anywhere near the battery life I had on kitkat,even lp couldn't match it,but I need a debloat script if any one has one,tried one I found on here already,but I couldn't use the back button,bit of a pain if I had to go bk one page,anyone got one I could use,thanks
