Samsung s7 fake?

[dvuder]

I bought a galaxy s7 on craigslist. It was listed as new Verizon model but was obviously used lightly. No burn in and few scratches. The price was good.

It works well and I was able to get it to work with the sim and even installed 930u firmware to use with att. Att was able to add emei to my account

I have never seen s7 before this but on this one there are small squares around the back and menu button and a number engraved in the left upper bezel to the left of Samsung logo

I did not see this in the s7 in another store after I bought it, also a Verizon model. The phone has a clean emei

Can anyone tell me if this is some kind of demo unit and if there is a chance this is not the real deal or the glass was replaced or something like that.

most likely a demo phone. the number is probably a serial # for tracking/inventory purposes/

If it was a fake then you'd not have been able to install the 930u firmware. Samsung firmware would hard brick a fake if you were able to install it on one in the first place.
