Samsung Galaxy S21 S991U 5G 128GB Review

The Samsung Galaxy S21 S991U 5G 128GB is a capable smartphone with a powerful processor, solid camera system, and a bright 120Hz display, though its plastic back and 1080p resolution were seen as compromises compared to its pricier Ultra sibling. It offers IP68 water and dust resistance, stereo speakers, and a fast under-display fingerprint sensor but lacks a 3.5mm headphone jack and microSD card slot. While offering strong performance and a durable build with Gorilla Glass Victus on the front, its 4000mAh battery may require more frequent charging for heavy users, and the 128GB of internal storage is fixed.

Key Features & Performance

Processor: Uses a powerful chipset, likely a Snapdragon (in the US) or Exynos, providing smooth performance for everyday tasks and apps.

Display: A 6.2-inch Dynamic AMOLED display with a 1080p resolution and an adaptive 120Hz refresh rate, offering a sharp and vibrant viewing experience.

Cameras: Features a triple camera setup with a 12MP main, 12MP ultrawide, and a 64MP telephoto lens, delivering high-quality photos with excellent color, sharpness, and low-light performance.

Battery: A 4000mAh battery provides enough power for most users to get through a day, though intensive use like streaming will drain it faster.

Storage: Comes with 128GB of internal storage, with no option for microSD card expansion.

Design & Durability

Build: Features an aluminum frame and Gorilla Glass Victus on the front for enhanced drop and scratch resistance.

Back Panel: Has a plastic back, which some reviewers found did not feel cheap and helped lower the phone's cost.

Durability: Equipped with an IP68 rating for water and dust resistance, and the front display is protected by Gorilla Glass Victus.

Missing Features

Headphone Jack: The phone does not include a 3.5mm headphone jack.

microSD Slot: There is no slot for expandable storage.

Charging Brick: A charging brick is not included in the box with the phone.

Overall

The Samsung Galaxy S21 5G is a solid, high-performance smartphone that delivers excellent cameras and display quality at a more affordable price than the Ultra version. While some compromises were made, such as the plastic back and fixed storage, it remains a capable device for most users, especially those looking for a compact and durable flagship experience.
