What have you come across an obscure device, or a wearable,
or something that you have no idea where
the data is going to be stored?
Often, there is minimal commercial support
for these devices.
You have the ability to go and recover these databases,
recover the plist files, and manually put
the truth together.
Do not be intimidated to do this yourself, and go out and grab
these databases of interest, and do some manual parsing.
Make sure you always look at the SD card.
If you have a certain device where the device prohibits
third-party application databases from living
internally on the phone, all of the data
will be on the SD card.
