I cracked the glass on my Samsung S3 Android device, so had to return it when I received my new one. I never did find a way to reset it back to factory default. I searched for an hour and tried a few different cookbook steps. None were entirely successful.
I ended up deleting everything I could manually. But, since it's flash memory, that means that only the pointers to it were deleted. The information itself is probably still in there.
For 99.99% of these kinds of situations, that's probably sufficient. It would take a moderately sophisticated snooper to even figure out the information is there, let alone dig that stuff out. And, if they get a high volume of phones, chances are they have easier targets to spend their time on.
YMMV. The security of deleting the information will vary from one device to the next.
