TL;DR: Is Refurbished Samsung Galaxy S24 Ultra Worth Buying?
The refurbished Samsung Galaxy S24 Ultra is a genuinely excellent phone. It has one of the best cameras on Android, a gorgeous AMOLED display, S Pen support, and Samsung’s longest-ever software commitment.
- Fancy a little more power for a bit more spent? The refurbished Galaxy S25 Ultra (512GB, unlocked) is the clean pick.
- For broader buying advice, KYM’s best refurbished phones guide covers top-rated second-hand handsets across all budgets.
If you’ve been browsing the refurbished phone database lately, the Galaxy S24 Ultra keeps showing up. And honestly, the hardware case for it is strong. Snapdragon 8 Gen 3, a 5,000mAh battery, a 200MP main camera, a built-in S Pen, and Samsung’s promise of seven years of Android updates.
On paper, it’s one of the best refurbished Android buys you can make in 2026. But the Galaxy S25 Ultra – for not much more – is a much smarter play in 2026.
Recommended Options
Galaxy S24 Ultra 256GB – Orange – Unlocked
Flagship S Pen power at half the new price.
- Display: 6.8-inch Dynamic LTPO AMOLED 2X, 3120×1440, 120Hz
- Processor: Snapdragon 8 Gen 3
- RAM: 12GB
- Main Camera: 200MP + 50MP + 10MP + 12MP quad
- S Pen for real productivity
- Huge sharp 120Hz display
- Top Snapdragon performance
- Strong zoom cameras
- Heavy and bulky build
- 45W charging is slow
Go for this if you need S Pen, big screen and pro cameras without new-phone prices. Refurb from Back Market at $545-$655 with 12-month warranty is a no-brainer. I'd pick 256GB for the storage headroom.
Galaxy S24+ 256GB – Green – Unlocked
Flagship Samsung power at mid-range prices via refurb.
- Display: 6.7-inch Dynamic AMOLED 2X, 1440 x 3120, 120Hz
- Processor: Snapdragon 8 Gen 3 / Exynos 2400
- RAM: 12GB
- Main Camera: 50MP + 10MP + 12MP triple camera
- Huge sharp 120Hz AMOLED screen
- Fast Snapdragon/Exynos power
- Solid all-day battery
- IP68 water resistance
- Limited to Android 15 max
- No wireless charging
Grab the S24+ refurb if you want flagship Samsung screen and speed on a mid-range budget—ideal from a two-year-old phone. Back Market's pricing saves 40-50% with solid warranty. Go for it over mid-range clutter; I'd take 256GB for the small extra storage peace.
But before you get too excited, there’s a critical caveat that most buying guides quietly skip over. Let’s talk about it now.
Is the Refurbished Samsung Galaxy S24 Ultra Worth Buying?
Yes, but only if the carrier-lock situation doesn’t affect you. The S24 Ultra is still a flagship-tier phone in every meaningful way: elite cameras, a stunning titanium-framed display, excellent battery life, and software support that stretches well into the 2030s. The hardware case is genuinely strong.
For more background on why carrier lock matters when buying refurbished, KYM’s refurbished phone FAQ hub covers everything you need to know before making a decision.
How Long Will a Refurbished Galaxy S24 Ultra Last?
This is where the S24 Ultra earns its reputation. Samsung committed to seven years of Android OS and security updates for the Galaxy S24 series, which means the phone should keep receiving major software updates into the early 2030s. For a refurbished Android device, that’s genuinely exceptional longevity.
A few years ago, buying a used Android flagship often meant accepting a short update runway. That’s not the story with the S24 Ultra.
The Snapdragon 8 Gen 3 chip inside is still outrageously capable in 2026. Day-to-day performance is fast, multitasking is effortless, and One UI has matured into something genuinely polished. Apps open instantly. Gaming performance is smooth. Samsung’s Galaxy AI features work properly and keep improving with each software release.
If software longevity is part of your decision (and it should be), the S24 Ultra is one of the safest long-term Android bets in the refurbished market right now. For a broader look at how software support affects long-term value, the iOS and Android update lifespan guide is worth a read.
What to Check Before Buying a Refurbished Galaxy S24 Ultra
Not all refurbished units are equal. Here’s what to look at before committing.
Battery Health
The S24 Ultra’s 5,000mAh battery is large enough that it tends to age better than smaller flagships. Still, aim for at least 85% battery health on any refurbished unit. Below that, you’ll notice reduced endurance quickly, and replacement isn’t cheap on a phone of this size.
AMOLED Burn-In
This is the Samsung-specific thing to watch for carefully. OLED burn-in happens when static elements like navigation bars, keyboards, or app interfaces get baked into the display after prolonged use. Check for ghost images on a solid white or grey background before buying. Most reputable refurbishers test for this now, but it’s still worth verifying.
S Pen Functionality
The built-in S Pen is one of the biggest reasons people buy the Ultra over the standard S24. Make sure pressure sensitivity is intact, Bluetooth Air Actions work, and handwriting input feels responsive. A damaged or missing S Pen is a real problem, and replacements are not cheap.
Camera Lens Condition
The 5x and 10x zoom lenses are particular weak points. Scratched or hazed lenses ruin the image quality in ways that can’t be fixed in software. Check for focus hunting or haziness before buying, especially in the telephoto modules.
Warranty and Return Policy
I wouldn’t touch a refurbished flagship without at least a 12-month warranty. Make sure the seller offers clear grading transparency, a meaningful return window, and battery health guarantees. Vague listings are usually vague for a reason. For help identifying trustworthy sellers, KYM has a dedicated guide to the best refurbished phone sites.
Refurbished S24 Ultra vs Refurbished S25 Ultra: Which Should You Buy?
If unlocked stock matters to you, this question essentially answers itself right now. The S24 Ultra is all carrier-locked at present. The S25 Ultra has unlocked variants available, including the 256GB unlocked in Titanium Jetblack, the 512GB unlocked in Titanium Gray, and the 1TB unlocked in Titanium Silverblue.
If you’re on AT&T or Verizon and comfortable with the carrier situation, the S24 Ultra is still worth considering. Here’s how the two compare in practice:
| Feature | S24 Ultra (Refurb) | S25 Ultra (Refurb) |
|---|---|---|
| Chipset | Snapdragon 8 Gen 3 | Snapdragon 8 Elite |
| Unlocked stock available | No | Yes |
| S Pen included | Yes | Yes |
| Software support | 7 years (to ~2031) | 7 years (to ~2032) |
| Galaxy AI | Yes | Yes (more refined) |
| Real-world speed difference | Minimal for most users | Slightly snappier |
| Price vs. new | Significant saving | Good saving, newer hardware |
The truth is, in normal everyday use, most people won’t feel the gap between the Snapdragon 8 Gen 3 and the Snapdragon 8 Elite. Both phones are absurdly fast. The more important consideration is whether carrier lock is a deal-breaker for your situation.
What’s the Best Storage Size for a Refurbished S24 Ultra?
If you’re going for the S24 Ultra and the carrier situation works for you, 256GB is what’s currently available in refurbished stock. For most users, that’s actually fine. Between apps, photos, and downloaded content, you’ll feel it eventually if you’re a heavy media user, but the average person won’t hit the ceiling quickly.
If storage headroom matters to you, the refurbished S25 Ultra in 512GB unlocked gives you both the extra space and the clean carrier status. That’s probably the stronger buy for anyone keeping a phone for three or more years.
Did You Know? Samsung’s anti-reflective AMOLED coating on the Galaxy S24 Ultra was a genuine upgrade over previous Ultra models. In direct sunlight, glare is noticeably reduced. If you use your phone outdoors regularly, whether for maps, photography, or just scrolling, it’s one of those things you notice immediately and then wonder how you lived without.
Should You Buy a Refurbished Samsung Galaxy S24 Ultra?
If you’re on AT&T or Verizon: yes, absolutely, assuming the carrier lock poses no issue for your situation. The hardware is exceptional, battery life is very strong, the cameras are still among the best on Android, and seven years of updates give it a long useful life.
If you need an unlocked device, the S24 Ultra is not the right pick right now. Go for the refurbished Galaxy S25 Ultra (512GB unlocked) instead. The hardware is newer, the software runway is slightly longer, and you won’t have any compatibility concerns.
If Samsung isn’t a priority at all and you’re open to other options, the iPhone range and Google’s Pixel lineup also offer strong refurbished value. For a full breakdown of the market’s best options, KYM’s top-rated refurbished handsets guide is the place to start.
Tech Tip: When comparing refurbished Samsung Galaxy pricing, always check whether a listing is carrier-locked before assuming it’s a deal. Carrier-locked phones can look attractively priced but may be completely unusable on your network without an unlock process that isn’t always straightforward.
Know Your Mobile Verdict
The Galaxy S24 Ultra is a brilliant phone hamstrung by one editorial reality: right now, every refurbished unit in stock is carrier-locked to AT&T or Verizon. If that works for you, it’s a strong buy. If you need an unlocked Samsung Ultra, the refurbished S25 Ultra (512GB, unlocked) is the honest recommendation, and the newer hardware makes it the smarter long-term investment anyway.
For current pricing and availability across the Samsung range, check KYM’s latest refurbished phone deals.
Pro-Tip: Filter for “unlocked” explicitly when searching for any refurbished Samsung flagship. Carrier-locked Galaxy stock is common, and a locked phone sold at a great price is only a bargain if it works on your network.
Refurbished Samsung Galaxy S24 Ultra: FAQ
Is a refurbished Samsung Galaxy S24 Ultra worth buying?
Yes, if it’s compatible with your carrier. The S24 Ultra still delivers flagship-tier cameras, performance, and a seven-year software update promise. The key caveat is that current refurbished stock is all carrier-locked to AT&T or Verizon, so check your network compatibility before purchasing.
Is the refurbished Galaxy S24 Ultra carrier-locked?
Yes, at present. All available refurbished Galaxy S24 Ultra units are locked to AT&T or Verizon. If you need an unlocked Samsung Ultra, look at the refurbished Galaxy S25 Ultra instead, which does have unlocked variants in stock.
How long will the Galaxy S24 Ultra keep getting software updates?
Samsung promised seven years of Android OS and security updates for the S24 series, which means updates should continue until around 2031. That’s an unusually long support window for an Android device, and it significantly improves the long-term value of buying it refurbished.
What battery health should I expect on a refurbished S24 Ultra?
Aim for at least 85% battery health. The Ultra’s large 5,000mAh battery ages better than smaller phones, but anything below 80% will noticeably affect endurance. Always check that the seller provides battery testing data before buying.
Should I buy a refurbished S24 Ultra or S25 Ultra?
If you need an unlocked phone, buy the S25 Ultra — unlocked stock exists for that model. If you’re on AT&T or Verizon and the carrier lock is fine, the S24 Ultra is the better value pick. In daily use, most people won’t notice a meaningful performance difference between the two.
What are the most common faults on refurbished Galaxy S24 Ultra phones?
AMOLED burn-in is the biggest Samsung-specific concern, particularly on units that were used heavily for navigation or gaming at high brightness. Beyond that, check S Pen functionality, camera lens condition (especially the telephoto modules), and battery health. A reputable seller should test for all of these as standard.
