If possible, add the model of the smartphone

I think this is not a good idea because it's private data and it doesn't contribute anything to understanding.
It's not necessary to know that the id device is an expensive phone ;-)

For me it will induce a feeling of "spying"

[pierromond]

Why not only the three first users with a medal symbol to reduce the "spying" feeling ?

[gpetit]

Hein ? The problem is only about the smartphone informations. For the rest it's perfect.
If you had smartphone informations :

• user may have a feeling of spying ("What ? They are tracking my smartphone ? They even know the model ?!)
• it will be more or less like a publicity
