I started to experiment with my old Samsung Galaxy Tab 10.1 (Google IO edition) running CyanogenMod Android 4.2.2 by using it exclusively as a replacement for a laptop.
I have been creating tutorials, so I have a need to take a lot of screenshots, since it is tricky, or rather not intuitive, I thought I need to share the shortcut:
Hold Power + Volume Down (side closer to Power) for 1 second.
The screenshot on this tablet is saved under, again not very intuitive:
I wish I kneew to to change that location to save to Google Drive, if you know please post a comment.
