No matter where you buy a new one it will be factory fresh.
Lol, obviously. But I mean in terms of build dates. Who gets the phones that were manufactured last week, and then sent out? Do carrier stores get first dibs? I saw someone on Reddit claim that their S10+ that was purchased from Best Buy had a mid April build date. Since we're in Mid May, where do the phones that are hot off the assembly line go first?
Edit: it may sound dumb, I know, but I'm really anal about not being an early adopter, and waiting until after the first few batches are sold.
