    Pretty good, I didn't expect interface/experience differences between T-Mobile and Unlocked versions of the S8 but I'll adjust. Only issue was a black spot of no screen in the bottom left of it's display, otherwise its perfectly fine and a great deal for the $67 I paid.

    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

    I have made several purchases before on this site with no problems and equipment was as expected. I think more diligence needs to be performed on a phone advertising Like new Excellent condition. Home Screen has red burn in from previous owners Home Screen. The front facing camera doesn’t work and the android proximity sensor doesn’t work. Screen goes black on receiving phone calls. I chose not to return this phone. Just wanted to give Back Market a heads up about their vendors slack.

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?

This is why we suggest buying all your devices from a dedicated refurbished retailer like us here at Back Market :) We offer a 1-year warranty on refurbished phones and a 30-day money back guarantee just in case you’re not 100% satisfied with your purchase. 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 :)

What's the best place to get an unlocked Galaxy S8 for sale?
