HTC Sensation sent screenshot to Google+ Instant Upload? I got a notification on Google+ this morning showing a screenshot of my HTC Sensation's home screen.

I checked my phone, and in the 'Camera Shots' album, there is the same picture.

I never actioned a screenshot to be taken, and didn't know my phone even took screenshots!

Why and how has this happened?
A lot of the recent HTC phones can take screenshots if you press Lock and Home at the same time, that may be what you're doing by accident.

As previously stated, the Google+ app by default backs up your pictures to a (private) online album for easier sharing. This can be turned off entirely, or configured to only sync on wifi (to save your data allowance) and give you a chance to delete unwanted pictures before they're uploaded.
