    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 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.

    Phone has missing part (SIM Tray) and was locked for ATT when it was meant to be unlocked. Backmarket agent unhelpful - have to return the phone to the vendor and wait for them to process before I can get a refund or replacement. Unacceptable.

    Phone did not work. Spent hours on phone with my provider and at the end of the day nothing. Refund could take over a week and my other option is to buy another and get a refund after I send other back. Why would I want to spend more money buying from you guys when my first experience was so very bad.

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.
