I'm looking for one that really does take screenshots, shows them, shows how to use itself, and doesn't have a bunch of annoying ads and/or intrusive permissions. Smart Touch and Screenshot Easy are apparently not it. If I can't use the off button on the right side of the S5, then I need something else for screenshots. What I've been doing for maybe a day is taking photos of the "old" phone's screen with the "new" one's camera. That doesn't work very well
