Is it possible the screen capture happened accidentally? The following links suggest that some Samsung phones have some combination of key presses that lead to screenshots:
Didn't see any mention of Samsung GT B2710 though...
Yes, she definitely took the screen capture accidentally. My son at 14 months old found out how to dial SOS (911 emergency services) whilst the phone keyboard was locked.
Thanks for the links. I tried equivalent key combinations to what they mentioned, but that didn't do it for this phone. Though there was no mention of the Samsung GT B2710 in those links, there was mention of the ability to do panoramic (stitched) photos, which I discovered the GT B2710 can do also - VERTICAL and HORIZONTAL!
The GT B2710 is not a fancy Android device, and does not have a touch-sensitive screen, but it does seem to be packed with tons of features, some of which are frustratingly buried in the non-intuitive tree of menus. One review of this phone that I read (PC World or something like that) said that they could not find its photo editing and retouch features! I eventually found them after quite a bit of hunting around.
All those features were just a bonus for me. I got the phone mainly because it was being sold at a special discount and is a good basic phone and is a "solid immerse" - i.e., TOUGH
- device. You can drive a car over it, drop it on concrete from 2 meters, dunk it in water and it works fine. I haven't driven a car over it yet, but it bounces without harm on concrete and even rings clearly if called when it's under water! It has a highly scratch-resistant screen and well-spaced keys that accommodate my spatula-like finger-ends.
By the way, it is also a GPS device, a compass and a pedometer (no kidding).
All these features are mentioned in the documention. Screen capture was not one of the documented features though!
