Distinguish Camera model of identical smartphones

[ben]

Hi everyone.

My  wife and me, we now use identical types of smartphones.
Is there any way I can distinguish pictures taken by these two cameras? Or is it possible to change the camera model name (bq aquaris x, android ?

Thanks for any advice,

I would start by looking at the metadata recorded in the image.
Many camera models fill out the make/model, the camera serial number of other tags which easily allow you to identify the camera.
