The jump from a Windows Mobile phone to Android was necessary one, considering Microsoft's decision to abandon mobile computing. I had read too many good reviews of the Galaxy series of phones and found this seller with a reasonable price in a non-black color. I find I really like the Orchid Grey. I ordered a Patriot 256 GB microSD in addition and haven't looked back. I am very pleased with the phone and carry in a pouch around my neck which was used for the also 6" form factor Nokia Lumia 1520 this Samsung phone is replacing.I really question the whole Locking/Unlocking requirements, but fortunately the Samsung phone has been taking OS updates successfully, so this seller is NOT misusing the "Unlocked" as a tease. I like the phone, great graphics, although many software writers do not accommodate the slightly narrower screen width in their rigid game field aspect ratios. >> I would buy from this seller again, should they have a similar good price for what I am looking for. No problems with the product that showed up nor the transaction/delivery. <<
