Surprisingly, I received a device from Italy with Italian apps WITHOUT an opening code, which was NOT sent to me even after enquiring with the sender. I only received instructions in Italian to return the device at my own expense !!! The fact that Black Market might be responsible/responsible is not mentioned anywhere ( shipper = guarantor ). Fortunately, I was able to open the device via YouTube and enter my PIN code. The smartphone : Samsung A51 5 G (2020) works perfectly. 😊🙋‍♂️

The phone is in very good condition: screen... On the other hand, the touch side of the phone is unreliable. The right side of the screen does not respond well. This leads to typing errors and having to start the message again, or errors in the PIN code. Sometimes you have to press 15 times in the same place to get the character to register... As it took me a long time to get it up and running after I received it, the return time had passed...

The speaker microphone doesn't work but unfortunately I can't return the phone as I need it to work. Or one would have to be sent back to me before I could return this one.

I am very happy with the purchase, it is as if the phone was new but at a much lower price. The only downside I can put is that the battery doesn't last as long as I expected, but it has a reasonable battery life. I would buy a refurbished phone from Back Market again without hesitation.
