My wife and I both use Pixel 3a phones, so later we sometimes can’t tell which phone took a given photo. Is there a way to add an identifying tag or ID to the metadata/EXIF on one phone so each photo includes that information automatically, or can it only be added afterward?

I think the real question is how to configure each phone to add an identifying tag.

With OpenCamera you can configure the copyright-exif marker that will be added to every photo

Yes. The practical options mentioned are:

Use a camera app that can write a metadata field automatically. Open Camera can be configured to add a copyright EXIF marker to every photo, which can serve as an identifier for one phone.
Add metadata afterward with ExifTool. You can write identifying fields such as copyright/rights or creator/author tags to JPEGs after capture. Examples given were using rights/copyright-style tags or XMP creator tags.

A simple approach is to assign one phone a unique value like a name in a metadata field such as Copyright, Rights, or Creator. Then you can search or filter by that field later.

If you want it embedded automatically at capture time, you’ll likely need to use a camera app that supports writing those tags, since the stock camera app may not offer that option.
