Why does nobody buy the Samsung Galaxy S21 5G anymore?
The key points in brief: The Samsung Galaxy S21 5G is Samsung's flagship from 2021, featuring a 120 Hz AMOLED display, triple camera with 3x optical zoom, 5G, dual SIM, and IP68 rating. Available from June 2026 at Revendo starting at CHF 206, refurbished, with a 1-year warranty and 14-day return policy. For anyone looking for a complete Android flagship without a premium for the release date, it is one of the most honest options in the range.
"That’s from 2021." True. And that’s exactly why it’s more worthwhile in 2026 than ever before.
The Samsung Galaxy S21 5G is the flagship the market has forgotten. And that’s your advantage.
What’s still inside the Galaxy S21 5G in 2026?
The S21 5G was Samsung’s flagship of 2021. Exynos 2100 processor, 6 GB RAM, 128 GB storage. At launch, it was the best Samsung had to offer. Today it’s a flagship that has long passed its price but not its hardware.
What the device offers:
- 6.2" Dynamic AMOLED 2X display with 120 Hz refresh rate
- Triple camera: 12 MP wide-angle, 12 MP ultra-wide-angle, 64 MP telephoto lens with 3x optical zoom
- 5G Dual-SIM (two physical SIM slots)
- IP68 certification: dustproof and water-resistant up to 1.5 meters
- 4000 mAh battery with 25 W fast charging
If you use WhatsApp, SBB, TWINT, e-banking, Spotify, and Instagram, you don’t need a newer device. The hardware meets the Swiss smartphone everyday needs without compromise.
Who is the Samsung Galaxy S21 5G worth it for in 2026?
The reliable everyday device under 210 francs. You don’t need a statement, a camera miracle, or AI features. You need a device that can do everything you do daily and doesn’t give up after a year. The S21 5G is exactly that.
The first smartphone. Yesterday still clothing size 128. Today there’s nothing but phone, phone, phone. The S21 5G does everything a child that age needs. And if it falls off the table, you sigh and grab the next one from the drawer. Definitely worth it at CHF 206.
The conscious choice. You buy refurbished not because you have to save money, but because you know that every new device costs resources that it doesn’t have to. The S21 5G comes with a MATT quality label and 1 year warranty. A flagship that already exists. Not a new device. No new damage.
Camera, display, 5G: What the S21 5G can still do today
Camera
The 64 MP telephoto lens with 3x optical zoom is no longer unique in 2026. But it is better than what is usually offered in this price range. Everyday photos, group shots, close-ups, short videos in 4K at 60 fps: the S21 5G consistently delivers good results. Night Mode works. Autofocus is fast. If you want to see specific test images, Teltarif offers a detailed camera test with everyday examples.
Display
The Dynamic AMOLED 2X panel with 120 Hz is still one of the best displays under 300 francs today. Contrast, color accuracy, and brightness are at a level that many current devices in this price range simply do not reach.
5G and Dual-SIM
5G is widely available throughout Switzerland, and the S21 5G supports all relevant frequency bands. The two physical SIM slots are a concrete everyday advantage: ideal for anyone who wants to use two numbers or two plans on one device. If you're also looking for a new subscription: With Revendo Mobile, there are affordable Swiss SIM options directly from us.
S21 5G vs. S22 vs. S23: What You Get at Revendo
| Device | Price at Revendo | Display | Telephoto camera | 5G | Dual-SIM (physical) |
|---|---|---|---|---|---|
| Galaxy S21 5G 128 GB | from CHF 206 (June) | 6.2″ AMOLED 120 Hz | 64 MP, 3× optical | Yes | Yes |
| Galaxy S22 256 GB | from CHF 256 | 6.1″ AMOLED 120 Hz | 10 MP, 3× optical | Yes | Model-dependent |
| Galaxy S23 256 GB | from CHF 348 | 6.1″ AMOLED 120 Hz | 10 MP, 3× optical | Yes | Model-dependent |
All devices at Revendo are refurbished, tested, with 1 year warranty and 14 days return policy.
The S22 and S23 have a higher resolution on the wide-angle lens (50 MP vs. 12 MP) and benefit from newer camera algorithms. However, the telephoto sensor on the S21 5G is more highly resolved at 64 MP. Those looking for optical zoom at the lowest price will do well with the S21 5G.
What the S21 5G Can No Longer Do and What Still Works
No Samsung Galaxy AI: The deeply integrated AI features from Samsung are reserved for the S24 and newer. What runs smoothly: All common AI apps like ChatGPT, Gemini, or Copilot work without restrictions.
Performance-Intensive Applications: The Exynos 2100 is not weak. Very demanding games or regular video editing run noticeably smoother on current flagships.
Software updates end in 2026. This makes no difference for everyday use.
