Samsung SAMSUNGSM-G975F/DSK-512GB Samsung Gal (Open Box)

Anyone buying this phone should be aware of two fairly obvious points: 1. It is not the U.S. model, so it has the Exynos chipset instead of Snapdragon, but that's the only option if you want dual-sim. 2. As it is not the U.S. model, Samsung Pay will not work unless you happen to be in the same country/region for which the device was made and have a bank account there. Google Pay should work as an alternative, if you live/have a bank account in one of the 28 covered countries. I wanted the dual-sim version and while I am from the U.S. I live in a country not covered by Samsung Pay, so these points were not dealbreakers. In benchmarks, Snapdragon always beats Exynos, but for regular phone users Exynos is more than sufficiently powerful and fast. The phone is definitely brand new but the package is opened to remove the region lock. The phone I received is apparently from the UAE, but it works fine on GSM networks in the U.S. in Europe. In the U.S. I used T-Mobile and had no issues on 4G/LTE. Indoor reception is not always ideal, but having previously owned Samsung phones, this seems to be a persistent issue for the company. The in-screen fingerprint reader is very good, but removing the included screen protector greatly improves the response. Face recognition is absolutely flawless. The only issue I have with this particular purchase is that included power adapter is a UK 3-pin and no U.S. or EU plug adapter is included.
