The difference between original and copies of mobile phones?

[dtm4]

Can anyone tell me how to spot copies of mobile phones? I am interested in copies of galaxy s3 and s4, but any general advice is welcome.
And I know it is a copy if it says Sasmung on the box...

Why would you be interested in copies? To scam someone?

Idk like look around on Ebay, very hard to spot on pictures if they are fake.

If the price is generally too good to be true and it's not a reputable seller, it's a 50/50% gamble at that point, and that's just theoretically.

I will be buying from local sellers, and will meet them in person so I can inspect the phone. Yes, the price seems too good, but it might be someone in desperate need of money.

Oh, local sellers. S3/S4 can be like $100 bucks, so it's not necessarily out of the world to find it for really cheap.

Open phone look info on the back of the phone, below battery cover.
Dunno, I'm just throwing tips randomly.

Don't buy if price is too good.

Why would you buy a copy and not the original?

If the seller is Mexican don't buy it, if Armenian, Russian, Indian buy it.
