Information on the web indicate the volume down + N button will capture a screen as a .png and put it in the screenshot subfolder of the pictures folder. However, when I capture, the .png is in a zip file of the log folder. Being inthe zip file, you cannot access to edit (crop, scribble, highlight, black out etc) it only gives you an option to print. Is there a way to change how/where it is saved? Why does my Nook HD+ zip it when others put in in the screenshot subfolder?
The only way I know how to do it is to download an app from google play. A screenshot app can both help you, save it in another location and edit it better. Hope this helps!
