Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What we like about Samsung Galaxy S21 5G (8GB + 128GB)

  • Excellent and vibrant 6.2-inch Dynamic AMOLED 2X 120Hz display with great outdoor visibility and brightness.
  • High-quality camera system that produces clear, bright, and detailed photos and supports 4K at 60fps and 8K video recording.
  • Fast and powerful performance, thanks to the Snapdragon 888 (US version) or Exynos 2100 processor and 8GB of RAM, handling multitasking and gaming smoothly.
  • Hand-friendly, compact form factor that is easy to use with one hand.
  • Durable design with Corning Gorilla Glass Victus front and an IP68 water and dust resistance rating.
  • Good, loud stereo speakers with quality audio.
  • Improved in-display fingerprint sensor that is faster and more accurate than previous generations.
  • Inclusion of 5G capabilities (both Sub-6 and mmWave).
  • Fast 25W wired charging support, along with wireless and reverse wireless charging capabilities.
  • Useful software features like the Director's View camera mode and Samsung DeX.

What we don't like about Samsung Galaxy S21 5G (8GB + 128GB)

  • No microSD card slot for expandable storage, which is a significant drawback for some users.
  • No 3.5mm headphone jack.
  • Battery life can be average and drain quickly with heavy use, with some users reporting heating issues, especially with the Exynos variant.
  • Does not include a charger in the box, requiring a separate purchase to utilize fast charging.
  • Features a 'plastic' (polycarbonate) back instead of glass, which some reviewers found disappointing for a flagship phone.
  • Lower resolution Full HD+ display compared to the S20's QHD screen (though many users don't notice the difference).
  • Software support is nearing its end (expected January 2026), making it a less advisable purchase in 2025/2026 due to lack of future updates.
  • Some minor software bugs, such as occasional random reboots or camera app issues, have been reported.

Verdict

The Samsung Galaxy S21 (8GB + 128GB) is a compact, high-performance flagship smartphone featuring a 6.2-inch Full HD+ Dynamic AMOLED 2X display with an adaptive 120Hz refresh rate and an in-screen fingerprint sensor, powered by either the Snapdragon 888 or Exynos 2100 5G processor. Its primary pros include a capable triple-lens rear camera system (12MP wide, 12MP ultrawide, 64MP telephoto) with advanced software features like 8K video recording and Director's View, fast and smooth performance, and IP68 water resistance. Primary cons include a "Glasstic" (polycarbonate) back instead of glass, the removal of the microSD card slot for expandable storage, the absence of a charger or headphones in the box, and potentially average or inconsistent battery life, especially with the adaptive 120Hz refresh rate enabled.
