How to identify moble phones?

[RamonaSteve]

My wife and I have identical Android phone.  When I import photos from the phones -- which is a pain -- the images from both phones have the same Make and Model in the EXIF metadata and the Serial Number is blank.  This makes it impossible to tell which photos are from which phone.

As a workaround, I need to set a keyword after or during import.  If I forget, there is no going back.

Is there a way that I am missing to tell which images came from which phone?

Thanks.

Upload a sample image from each phone to Dropbox, Google Drive, or similar and post the sharing link here. We can see if there is "hidden" metadata you could use to distinguish them.

@johnrellisIs there a tool that I can use to look at the metadata?

ExifTool will ferret out every single piece of metadata in a file.

Thank you, @dj_paige.  I'll check it out.

I looked at all of the EXIF data and was not able to find anything that could identify the phone.
