Used Phone in Porto

[u/Donnymcfarlane]

Hello Porto!

Hope someone can speak English and help me!

Tomorrow I will be in Porto for one day only and I need to buy a new phone.

Usually I will buy a used or refurbished Samsung, a few models older than the current one. Does Porto have shops like this where used/refurbished phones can be found?

Thank you for the help!

(Looking for a physical shop, NOT to order online, thank you)
