You've done all of these steps, and you're
like, all right, Heather, I've exhausted all my options.
Or sadly, maybe you don't have the access you need.
Maybe you don't have a full file system acquisition,
so you're missing a lot of these files.
Examine the databases you have access to.
Use your Android cheat sheet.
It's very important.
On the Android cheat sheet, it is
going to list which versions those files exist on.
So it will show you from Android 4
all the way through Android 12, so you're not
wasting your time.
Did you examine the SD card?
Can you find anything there?
Have you keyword searched properly?
Did you keyword search in hex and in content?
Have you looked for application snapshots?
Is your extraction capable of carving for more?
You can always try that.
And if you're at your wits end and you don't know what else
to do, can you get legal authority
to collect from Google?
