The Samsung Galaxy S21 Ultra comes with a revamped design, featuring the camera module prominently highlighted with an elegant cut-out design. Its nearly bezel-less Dynamic AMOLED display, with an optimal aspect ratio, is equipped with a dynamic refresh rate ranging from 10 to 120 Hz, ensuring smooth scrolling and fluid playback of videos and games. Additionally, the display allows for precise inputs with the separately available Samsung S Pen. An octa-core processor and optimal RAM deliver swift performance for demanding applications and games. The quad main camera captures stunning images with fine details, utilizing a 108-megapixel main sensor and two optical lenses for zoom (1x 3x and 1x 10x). The 40-megapixel front camera not only takes great selfies but also enables secure and instant unlocking of the smartphone. The Galaxy S21 Ultra provides the usual robustness and security expected from a Galaxy smartphone, with both the front and back protected by durable Gorilla Glass 7. Thanks to its IP68 certification, the S21 Ultra is also resistant to water and dust. A powerful battery ensures all-day endurance, and with Wireless PowerShare technology, it can also charge Galaxy Buds or Galaxy Watch. The reliable ultrasonic fingerprint sensor under the display allows for quick and secure unlocking of the smartphone. This phone can accommodate more than one SIM card, enabling the use of multiple mobile subscriptions simultaneously. This is particularly convenient for separating business from personal use or for utilizing an optimal local subscription while abroad, without sacrificing accessibility under the familiar number.
