The SIM card tray was cracked along the edge and it was tricky to reinstall without further damage. Luckily I had an old S8 and I swapped the trays. Other than that the phone functions as expected. 4th purchase on BM 1st issue.

Phone was in top condition, fast delivery, great value for the price. It is a great phone for standard use - calls, texting, apps, and more. Camera is very nice and just the write size for me^ want to be able to use the phone fully on one hand only. Would definitely recommend.

Very happy, the phone looked and operated like it was brand new. Transferred all my data from the old phone to the new Black Market phone with no problem. Shipping was fast. I don't expect any, but so far I have no complaints with Black Market...

I ordered a fair condition phone but felt almost new. It had just 2 micro dents on the frame which were hard to notice. Battery backup is good and easily lasts a whole day for medium use. A full charge gives a solid 3 hours screen on time or 2.5 days on standby

The customer service is great! Shipping was right on time, happy with that. Phone looks great, however; the volume is so low I have to put it on speaker to hear when on a phone call. My previous Galaxy S8 was fine, I had no problem hearing.

Is the unlocked Samsung Galaxy S8 a good phone?

From my experience, every premium device sold by Samsung will give you quick performance and customization. Even though you won’t get the newest Android version on the unlocked Galaxy S8, you’ll still have a phone that feels modern and works great. Samsung is praised for their screens; they’re great for watching videos because of their amazing color contrast and OLED technology. Also, if you’re tech-savvy, these phones are great for “rooting” because of their impressive specs and developer support.

What if I don’t like my unlocked Samsung Galaxy S8 after buying it?

And since these models are unlocked, they’ll work for just about any carrier here in the US. Verizon, AT&T, T Mobile, we got you covered :)
