Last month I created a physical image of an Android 7.x test phone and made it available to the DFIR community for testing, education, and research. As part of this project, robust documentation was created in order to document aspects of the test phone and all of the apps that were populated with user data along with said data. Takeout data is also included for the ESPs that provided it. A .ufd file is included for good measure.
Thanks to Devon Ackerman of AboutDFIR.com and Jessica Hyde of Magnet Forensics who both made it possible.
You can find the image and related materials here.
