Android 5.1 vs Android 6: Delete Screenshot
Something that's been available from Samsung and other 3rd party phone makers for years, but never stock Android, is the ability to delete a screenshot right inside the notification pulldown bar. As you can see on the left Android 5.1 you can only share, but with 6.0 on the right we can now share then delete it. It's just one more way we can easily do things quickly. Not go into our gallery, find an image, open the screenshots folder, then delete it. It's just right there. This should have been added years ago, but now it's finally here.
