Epic 4G capacitive buttons With many of you Sprint users gleefully setting up those new Epic 4Gs, its time to give the newest WiMax phone some tip love. If those capacitive buttons just aren't staying lit long enough for you, delve into Menu > Settings > Sound and Display > Keyboard Timeout. Increasing this value will keep those familiar Menu, Home, Back, and Search buttons glowing strong. Or, if you don't want them to blemish that SAMOLED screen, you can reduce the timeout. Thanks to Android Central Forums user excalis for the tip!
