Was I given a refurbished Z Force phone

[Jaj4e]

I bought the Moto Z Force from Best Buy. It received the Nougat Update The day after I got it. It would randomly freeze up at least once a day & the battery drained fast. After researching everywhere I called Motorola who told me they had put a hold on the Nougat updates being pushed due to complications it created with the phone & that I could return mine to Best Buy (it was less than 2 weeks since I get it) & get a new one & the Nougat Update would not be pushed through so I could avoid the problems. Well I did that & Best Buy pulled the phone out from where they have the phones & swapped me over. Well guess what? This new phone came with Nougat on it. I also looked at the settings & it says last FDR was Jan. 21 2017 at 6:03 am. Does all this mean they gave me a reconditioned/returned phone or is it possible that it was just manufactured & shipped at a later date (Jan. 21 2017) & from different stock than the other phone & came with the update already? Everything was sealed up on it like it was new.
