I bought the phone in September.
The reps would probably know....
I didn't speak to any reps on the sales floor. Actually, I don't think there were any reps on the sales floor. The only people there were the cashiers and they'll get a new phone from the back when you need it.
I researched the phone before I got it so I knew what I was getting. Maybe you check out the specs on the Xiaomi Hk site first just to make sure. Also, keep in mind that the phones don't come with the north American style charging plug and there is no option to buy one at the store as they don't have any.
