Value Position in 2026

At the listed price tier around €293.32 / $255.00 / £238.75, the Galaxy S21 Ultra 5G sits in a strong legacy-flagship bracket. You get high-end materials, a QHD+ 120Hz panel, advanced zoom cameras, and flagship-grade connectivity that many newer midrange phones still do not combine in one package.

Design and Build Quality

The phone uses Gorilla Glass Victus on both front and back with an aluminum frame, plus IP68 water and dust resistance. It is not light at 227-229 g, but the tradeoff is a sturdy build and support for stylus input, which adds productivity flexibility.

Display Experience

The 6.8-inch Dynamic AMOLED 2X display remains a major reason to buy this model. With 1440 x 3200 resolution, 120Hz refresh rate, HDR10+, and up to 1500 nits peak brightness (1023 nits measured), it still delivers a flagship-level viewing experience for media, reading, and gaming.

Performance and Hardware Variants

Performance depends on region: Exynos 2100 (international) or Snapdragon 888 (USA/China), both built on 5 nm and paired with fast UFS 3.1 storage. Memory options scale up to 16GB RAM and 512GB storage, and test results such as AnTuTu 657150 and GeekBench 3518 show it remains comfortably capable for heavy daily use.

Camera Strengths and Limits

The quad rear setup is still one of the most versatile in its class: a 108MP main camera, 3x telephoto, 10x periscope telephoto, and ultrawide. It supports 8K video and strong stabilization features, making it especially attractive for users who prioritize zoom range and multi-scenario shooting over newer but simpler camera stacks.

Battery Life and Charging

A 5000 mAh battery and a 114h endurance rating (older test) point to reliable longevity. Charging is practical rather than class-leading by current standards, with 25W wired, 15W wireless, and 4.5W reverse wireless charging.

Software and Daily Features

Samsung launched it on Android 11 and committed to four major Android upgrades, with One UI 6.1 available. Features like Samsung DeX, Wireless DeX, an ultrasonic in-display fingerprint sensor, and Circle to Search help it feel more complete than many devices at similar pricing.

Connectivity and Network Flexibility

Connectivity remains a highlight: Wi-Fi 6E, Bluetooth 5.2, NFC, USB-C 3.2, and broad global positioning support are all onboard. Network support is extensive across 4G and 5G, including mmWave on SM-G998U1 and strong Sub6 support on SM-G998B, so choosing the right model for your carrier still matters.

Who Should Buy Samsung Galaxy S21 Ultra 5G

This phone is best for buyers who want premium display quality, long-range camera zoom, and flagship extras without paying current flagship prices. If your priority is very fast charging, microSD expansion, or a lighter body, newer alternatives may fit better.

Conclusion

Samsung Galaxy S21 Ultra 5G remains a smart buy for users who want an affordable former flagship with excellent display quality, versatile cameras, and complete connectivity.
