Key Highlights

The Samsung Galaxy S21 Ultra stands tall as the most premium and powerful device in Samsung’s flagship lineup, combining top-tier hardware with a refined design. With its stunning 6.8-inch Dynamic AMOLED 2X display, ultra-sharp 1440 x 3200 resolution, and exceptional brightness, it delivers one of the best viewing experiences on any smartphone. Samsung has also equipped it with a massive battery and one of the most versatile camera systems ever seen on a Galaxy device, making it ideal for photography enthusiasts and power users alike. Interestingly, Samsung—after previously mocking Apple—has now adopted the same accessory-lite approach, offering the S21 Ultra without a charger, headset, or OTG adapter. Compared to the S20 Ultra, the new model is slightly smaller but features a refreshed design and upgraded internal components. It comes in variants starting with 12 GB RAM and 128 GB storage, going up to 16 GB RAM and 512 GB storage. Since the storage is non-expandable, choosing the right variant upfront becomes essential. In regions like Europe and India, Samsung ships the device with its revamped Exynos 2100 chipset. While past Exynos models lagged behind Snapdragon counterparts, Samsung claims significant improvements in performance and efficiency this time around. Paired with Gorilla Glass Victus and IP68 water and dust resistance, the S21 Ultra delivers durability along with flagship performance. The camera experience is where the phone truly shines. The 108 MP main lens captures detailed shots in daylight, while lower-resolution night images are recommended for better clarity in low light. The 3x telephoto and ultra-wide lenses perform well, although the 10x optical zoom and 2x digital zoom remain less impressive. Launched in early 2021 and priced from ₹48,990 in India as of November 2025, the Galaxy S21 Ultra continues to be a strong choice for users seeking premium performance, superb photography, and a feature-packed Android experience.
