Why choose the refurbished Galaxy S21 in 2026?
The Galaxy S21 was Samsung’s flagship in 2021 and, five years later, remains a fast and capable phone. It has a Dynamic AMOLED 2X 120 Hz display, flagship processor (Snapdragon 888 or Exynos 2100) and a versatile camera set with zoom. For everyday use - social media, messaging, photography, video - it handles everything without hesitation.
The main advantage is the price. The S21 is the most affordable Samsung flagship in refurbished form, from €144 at iOutlet, with 24 months warranty. An A‑grade S21 is hard to tell apart from a new one, and the battery is tested with specialised technical software before sale.
Being a 2021 model, it is closer to the end of major Android updates than newer models. That is why the price is so attractive. If you want the longest possible lifespan, look at the S23; if you want the best price for a premium Galaxy, the S21 is unbeatable.
Who does it make sense for?
- Who wants the cheapest Samsung flagship - 2021 flagship at entry‑level price.
- Who is moving from an old or low‑end phone - the jump in screen size and smoothness is massive.
- Who is getting their first premium smartphone - great value for money for a young person or a secondary phone.
- Who doesn’t care about always having the latest Android version - the S21 remains safe and speedy for everyday use.
Galaxy S21, FE, S21+ or Ultra: which to choose?
- Galaxy S21 (from €144) - the compact 6.2" model. Balanced and easy to use with one hand.
- Galaxy S21 FE (from €154) - the "Fan Edition" at 6.4", with a larger battery. Most of the S21 experience for a little more.
- Galaxy S21+ (from €149) - 6.7" display and longer battery life. Because it is less in demand, it sometimes appears at prices close to the base S21, making it a good opportunity.
- Galaxy S21 Ultra (from €212) - the 2021 top‑end: 6.8" display, 108 MP camera, optical zoom up to 10x and S Pen support. Still today a respectable photographic machine.

Prices by grade - and what they mean
At iOutlet, the price of a refurbished Galaxy S21 varies mainly with the condition grade, which describes only the external appearance. Performance is the same across all grades.
| Grade | Galaxy S21 from | Condition |
|---|---|---|
| Grade C | €144 | Good condition, with visible signs of use |
| Grade B | €154 | Very good condition, small marks on the chassis |
| Grade A | €219 | Excellent condition, minimal marks |
| Premium | €266 | Like new, no visible marks |
Indicative prices, which vary with available stock. Check the refurbished Galaxy S21 page for current prices and colours.
Which grade to choose? If you plan to use a case, Grade C gives you the same phone for the best price. If you want an immaculate appearance, choose Grade A or Premium.
Updates: how long does the S21 last?
Be honest with yourself about this point. The Galaxy S21 launched with Android 11 and has already received its major Android updates over the years, and it continues to receive security patches from Samsung. In terms of new system features, it is closer to the end of its lifecycle than a recent model.
For most people this isn’t an issue: the phone remains fast, secure and does everything you need. But if your priority is to have the latest software features for as long as possible, it pays to look at the S23 or the S24. If you’re after the best price, the S21 delivers and more.
