    • Near-Perfect Phone
I bought this Samsung phone to use as an upgrade to my old iPhone XS, and this phone passed in quality for sure, even exceeded expectations that I had as a user. 1. The camera quality on this phone was top-notch, providing an extremely far yet clear zoom, and extremely clear selfies whenever I decided to take them 2. The fingerprint sensor is a bit hesitant at first, but you'll get used to exactly how it works over time, and the face recognition is perfect, with it recognizing my face every time I try to enter the phone. 3. The battery generally lasts even longer than what is promoted, surprising me a lot whenever I got this phone and is a major plus for me when vouching for others to get it to my friends and family As a whole, this phone was a great purchase, and for its price, it is a great investment. ... show more

    • Another fine Samsung phone
Color: Phantom Green Size: 256GB
I've been using Samsung phones since the Note 4, and I have no regrets. This latest model is pricey, yes, but the battery lasts a long time, the screen is sharp, and the camera takes great pictures.

    • Legit !!
Color: Phantom Green Size: 256GB
I unfortunately had the experience of buying an S23 Ultra on ebay and while trying to get the phone to work, I received and MCK code error. I called up Tmobile with the serial number and they confirmed the phone was either stolen or had a balance to pay off before I could use my Sim card in it for myself. Long story short, I returned that one and bought this one on Amazon. Took my Sim card out of my S22 and threw it in this S23 Ultra and it fired right up and was able to use. Pretty straight forward and the phone is phenomenal. Buy here from a trusted seller, you will not be disappointed ! ... show more

    • I'm Finally Current & Beyond
I use my phone for Work & Pleasure. I Love Living the Glory Days at Rock Concerts and I Finally have the BEST Camera on the Planet, for the Whole Last Year. I Can't wait til Next week to try it out. 200mp Camera, 8K Video. I also got mine with 512gb of Storage and 12gb of RAM. This One is a Global Model and handles Everything: 2G, 3G, 4G and 5G. I don't even hook up to the Company WiFi + I'm in a building that has Tons of Steel for Interferance and a Computer/IT Room that's almost as Big as my garage & they run on Verizon. The past week, I do Everything from my desk, whether I'm using the phone, adding emojis to a text, sending Pictures or sending emails; It ALWAYS WORKS, even if I forget to turn on Regular WiFi, Not Company WiFi. No more walking 75 feet to the window to try and get a Signal. No more Walking out to the Parking Lot to try and get a Signal. Ya gotta do your Homework and Granted, Everyone Wants a Deal, but sometimes If you Want the Best, you gotta Pay for it and It's Actually Worth it. I made sure that I had this thing as Loaded as I could afford & I am fully Satisfied. 😎👍🏻 ... show more
