Experience a pocket-sized cinema with the Samsung Galaxy S21 Ultra (5G). Its 6.8 inch Dynamic AMOLED 2X display with 120 Hz refresh rate delivers buttery‑smooth scrolling and HDR10+ colours that rival a high‑end TV. Under the hood, the Exynos 2100/Snapdragon 888 chip and up to 16 GB of RAM give you workstation‑grade performance in the palm of your hand. The quad‑camera system pairs a 108 MP main sensor with dual telephoto lenses offering 3× and 10× optical zoom and a 12 MP ultrawide lens, so you can switch from wide vistas to far‑off details like a DSLR with interchangeable lenses. A 40 MP front camera keeps selfies crisp. The 5 000 mAh battery supports 25 W wired and 15 W wireless charging, while IP68 water resistance and S Pen support add durability and versatility. With 5G connectivity and up to 512 GB storage, it’s as future‑proof as flagships come.
