I'm used to the Palm Treo 700p, running Palm OS. On Palm OS, the system clipboard can hold only text.
I now also own a Samsung Galaxy S Relay, running Android "Jelly Bean" 4.1.2. This is a phone rather similar to the Samsung Galaxy S III, but with a slide-out physical keyboard included.
I take screenshots in the usual way it's done on a Galaxy S Relay. I hold the Power + Home keys at the same time for a few seconds until I see a white border around the edge of the screen. (Not for too long. I don't want my phone to suddenly power off without saving anything to disk.)
Now:
Like a Galaxy S III, my phone then saves a screenshot to a "Screenshots" photo album.
Like a Galaxy S III, my phone shows a notification labeled "Screenshot captured". I can expand the notification using two fingers to see a preview of the top few centimeters of the screenshot, and then can tap "Delete" or "Share".
And, like a Galaxy S III, my phone displays a pop-up "toast" message at the bottom of the screen which says
Copied to clipboard
.
Hold on. What? The screenshot was copied to the clipboard?
Can the clipboard, in any version of Android, hold images?
