I do this accidentally far more than I do deliberately. It's a nice feature for certain occasions but I can't say I use it very often. I accidentally trigger it frequently when I hit the home button to exit an app and then hit the sleep button right after. Often I don't notice I've done it until I open my photos and see an all black image or a picture of my home screen. I know there is a tweak to disable the feature altogether but I still like to have it for when I need it, such as capturing a texting conversation or a picture on a site that does not permit you to save or copy it. What would be a good solution to this?
