  • Fantastic phone and arrived in great condition
The phone arrived in excellent condition but didn't quite match the image provided by the seller. The blue s21 ultra pictured had a carbon fiber like finish on the camera bump but the one i received was solid blue on the camera bump. No complaints it's still a great looking phone that works perfectly but just something to note. Very happy with the product that arrived and would definitely buy again from the seller. ... show more
