Phone Name in Find my Samsung

[Dulcinea]

I have two identical Galaxy. I have changed the name of each one, but on the "Find my Samsung" website they both appear with the same name, which is that of the model and not the name that I have assigned. 

How can I differentiate them so as not to make mistakes? 

Thank you.

Hello, in Find my mobile the name of the device wue you have assigned in the phone settings appears. Go to Settings /About Phone, above all in Edit, change device name
