Product Title

Samsung Galaxy S21 Ultra 5G (Unlocked) – 6.8″ Dynamic AMOLED 2X QHD+ 120Hz Display, 108MP Quad Camera, 100x Space Zoom, S Pen Support

Product Description

Redefine what a smartphone can do with the Samsung Galaxy S21 Ultra 5G. Engineered for those who want the absolute pinnacle of mobile technology, the S21 Ultra features a massive 6.8-inch Dynamic AMOLED 2X display. This was the first Galaxy screen capable of running at a crisp Quad HD+ resolution while simultaneously maintaining a buttery-smooth 120Hz adaptive refresh rate. With a peak brightness of 1,500 nits and HDR10+ certification, it provides an unmatched cinematic experience, even under direct sunlight.

The Galaxy S21 Ultra 5G is a creative powerhouse, featuring a professional-grade 108MP Quad Rear Camera system. Unlike its predecessors, it utilizes a Dual Telephoto lens system (3x and 10x optical zoom) that works in tandem to provide a remarkably steady 100x Space Zoom. With 12-bit RAW support in Pro mode, photography enthusiasts have DSLR-level control over their shots. For the first time ever on an S-series device, the S21 Ultra brings S Pen compatibility, allowing you to sketch, annotate, and edit with precision. Powered by the 5nm Snapdragon 888 and a colossal 5,000mAh battery, this phone is built for a life that’s always “on.”

Key Features & Specifications:

  • 8″ QHD+ Dynamic AMOLED 2X: The most advanced Galaxy display, featuring a curved edge and an intelligent refresh rate that scales from 10Hz to 120Hz.

  • Dual Telephoto Zoom: Two dedicated zoom lenses (3x and 10x) provide the clearest long-range shots in the industry with AI-powered Zoom Lock.
  • S Pen Support: Bring the productivity of the Note series to the S-series for precise editing, drawing, and note-taking (S Pen sold separately).
  • 8K Video & Director’s View: Record cinema-quality 8K video or use Director’s View to see and switch between all lenses while filming.
  • 5,000mAh All-Day Battery: A massive battery capacity designed to power your 5G lifestyle, supported by 25W Super Fast Charging.
