Im runnin rooted froyo but when I use my extended battery everytimw I hit power it takes a screen shot. Yeah I know its built in now when u do power+back button it takes one but all I do is press power. Also it randomly goes back pages when im in browser. Its like the back button is sticking( how idk) but its only when I use my extendes battery wtf is wrong??? And yes im using a samsung extended battery not a cheap knock off so I kno it aint that
