In copying files from my mobile phone (Samsung GT B2710), I discovered this image saved in the phone's internal memory (i.e., not in the added memory card):
The thing is, this image appears to be a copy of all the pixels in the phone's display, as it would have appeared on the date and time it was saved: 2011-12-31 23.40.30 (New Year's Eve) - date/time taken from the image details as saved in the phone's internal memory. The image itself doesn't seem to have any attached EXIF record though.
In the image, the network operator is shown as 2degrees - which is correct. The phone is using a 2degrees SIMM, the number itself having been ported from another network operator (Vodaphone) in early 2011.
My daughter Lily is a dab hand with all things digital - computers, cameras, game devices, remote controls. She had been busy preparing to take pix on the run-up to midnight and the New Year's fireworks display, and I suspect that my phone was used at some stage, and the display captured as per the image shown above. She does not recall what she might have done to do this.
I've pored over the handbook and online user guides, spent hours researching phone hacker forums online and playing with the phone (and discovering some other things it could do that I did not know of before), but for the life of me I cannot figure out how the heck she captured the phone display.
