Why we picked it #1

If you want total peace of mind with your used S23 purchase, this is the option to beat. You’re getting a Galaxy S23 in excellent, refurbished condition—and the big deal here is that it’s factory unlocked, certified refurbished, and comes from a top-rated, highly trusted seller. What really sets it apart is the 12-month manufacturer warranty that’s somehow still in effect, which is rare for a 2023 S23. You also get same-day shipping if you order in time, direct seller support, and the genuine Samsung charger (not a generic one). It covers return costs for you and gives you 30 days to change your mind. Where it shines is on peace of mind: most other options are cheaper but don’t include that manufacturer warranty, authentic charger, or certified refurb status. You'll pay more upfront than for something in just “Good” or “Very Good” condition (and certainly more than carrier-locked or AT&T-only listings), but you're getting what amounts to the closest thing to “new” in this price range. If you want zero hassle and maximum reassurance that what you get will just work—and keep working—this is hands-down the buy. The only real tradeoff? You’re paying a little more, but you get a lot more security—worth it for most buyers.

Why we picked it #2

If your main goal is to spend as little as possible and you’re okay with some tradeoffs, this listing will save you money. For just $185, you’re getting a refurbished S23 in “Good” condition—which means it’ll show more wear than pricier listings, but should still function well. The seller is well established, highly rated, and offers a 30-day return window, so you’re protected if something’s wrong. Plus, the battery is reported to be at 95%, which is above average for a 2023 device. The biggest catch is that it’s locked to Verizon, so you can’t use it on other carriers. If you try to unlock it and fail, you can’t return it, so only go for this if you’re a Verizon user or 100% sure you know how to unlock it successfully. Also, you don’t get the original packaging or a genuine Samsung charger—just a generic cable—so the unboxing experience is minimal. You’re giving up flexibility and some polish compared to the top pick (which is fully unlocked and comes in excellent condition with a real Samsung charger), but the price difference is significant. If you’re on Verizon and don’t mind some wear, you’ll get a solid phone for a bargain.

Why we picked it #3

This listing splits the difference between affordability and condition. You’re getting a refurbished S23 that’s in “Very Good” shape—nicer than the budget options, with only minor wear—and sold by a top-rated, trusted seller. The price remains below many unlocked or “Excellent” listings, so it’s a good compromise if you want something tidy but don’t need “like new.” There are some catches you’ll want to know about. First, this one is carrier-locked to Verizon—so it won’t work on other networks unless you unlock it yourself. Unlike some carrier-locked deals, you do have a 30-day return window, so you’re protected if anything’s wrong out of the box. Just know that the packaging is generic and includes only a third-party charger, so don’t expect Samsung-branded extras. Compared to the top unlocked pick, you give up universal compatibility and that “nearly new” look, but you save a meaningful amount of money. This is a sensible middle ground for Verizon users who want a device that looks good but costs far less than “Excellent” unlocked listings.

Why we picked it #4

This listing gives you an unlocked S23 at a reasonable price, so you can pop in almost any SIM you like—no carrier lock headaches. The phone is refurbished in “Good” condition, so expect visible but not excessive wear. If you don’t mind that, you’re scoring a major discount compared to top-tier listings. The seller is extremely well established and highly rated, with an easy return process if anything goes wrong in the first 30 days. While the price is solid, you’re not getting the best of the best here—paying a bit more would get you “Very Good” or “Excellent” devices from the same or similar sellers. Also, the charger included is third-party, and there’s no original box or accessories, so the overall presentation and extras are basic. There are also some shipping and payment quirks if you’re an international buyer or in a hurry over the weekend. Overall, this is a flexible, practical pick if you want unlocked freedom and don’t mind a bit of cosmetic wear. If a few scuffs help you keep more cash in your pocket, this is easy to recommend.

Why we picked it #5

Looking for a phone that feels nearly new but still saves you a chunk compared to buying brand new? This “Very Good” condition S23 strikes a sweet spot. You’re getting a factory unlocked phone—no carrier restrictions—so you’re covered no matter your carrier. The device should only show minor signs of use, and the seller is established and gets stellar feedback. The 30-day return policy gives you breathing room in case something doesn’t feel right. Compared with cheaper, carrier-locked, or “Good” options, you’re paying a bit more, but you’re rewarded with a cleaner looking device and more flexibility in how you use it. There’s even an ejection pin included, which is a nice little touch (most on this list skip small accessories). On the flip side, you don’t get original packaging or a genuine Samsung charger—the accessories situation isn’t as complete as with the top-ranked choice. Shipping is U.S. lower 48 only, so you’ll need a U.S. address. All said, this listing gives you great blend of condition, compatibility, and value—perfect if you want a phone that’s a step above entry-level, but aren’t willing to pay new-phone prices.

Why we picked it #6

If you want a phone that looks and feels almost new (but don’t want to pay new-phone prices), this is a strong pick. The condition is “Excellent—Refurbished,” so you’ll get minimal wear and a smooth, polished experience. The phone is factory unlocked, which means you’re completely free to choose or switch carriers. The seller is very well regarded and accepts returns for 30 days, covering your return shipping if you need it. Compared to the top-ranked listing, you miss out on a manufacturer warranty and a genuine charger (this one includes a third-party charger), and there’s no certified refurb status—so a bit less safety net and polish there. Shipping is only within the U.S., and if you have any plans for international use, be aware that the warranty will be voided if you send the phone abroad. In short: if you put a premium on a device that looks great in your hand, and want unlocked flexibility—but don’t need the extra warranty or Samsung charger of the #1 pick—this option lands right in your sweet spot, with a savings to match.

Why we picked it #7

This is the lowest-priced way to score a Galaxy S23 outright, but you give up on a few comforts. The phone is fully used (not refurbished) and carrier-locked to Spectrum, so you’ll need to be on that network or willing to figure out an unlock yourself. The good news is that the battery is stated to be in “Grade A” condition, and you’re still getting the full feature set of the S23 at a bargain price. In terms of what you’re missing: the listing does not include a charger, a SIM card, or original packaging, and the cosmetic condition will likely reflect real-life use instead of “refurbished polish.” Compared to the top listings here—which offer certified refurb status, warranty, and clean accessories—this one is no-frills. The seller does accept returns, but you have to pay return shipping, adding a little risk if you’re not satisfied. If you’re okay with basic cosmetics, don’t mind sorting out your own charger, and plan to stick with Spectrum (or know exactly how to unlock), this is easily one of the cheapest ways to get into a high-end Samsung. But if you want a warranty, fewer surprises, or universal compatibility, it’s worth considering a step up for a bit more money.

Very Good - Refurbished

$228.99
View on eBay

Why we picked it #8

This listing gives you a “Very Good” refurbished S23 from a top-rated seller, and it’s unlocked—so you have full carrier freedom. It includes a generic UL-certified charging cable (so there’s something, but not a Samsung original), and the phone will have only minor wear. You also get free shipping and a 30-day return window with return shipping covered, keeping things low risk. Compared to the best-value picks up top, you’re paying a bit more and missing out on the “Excellent” near-new finish. You’re also not getting a manufacturer’s warranty, and if you ship internationally, you’ll void any warranty the seller provides—so this is best if you’re in the U.S. and not planning to send it abroad. There are more restrictions on payment and no address changes after purchase, so double check your details before you buy. If you’re after a solid, dependable S23 that’s just shy of perfect condition and want the unlocked flexibility, this is a sound middle-ground—giving you reliability, a good seller, and genuine value, even if it’s not the absolute bargain or most “like new” option on the list.

View on eBay

Why we picked it #9

This S23 is listed in “Very Good” refurbished condition, so you’re getting a device with only light wear—perfect if you want something that still feels premium in your hand. It’s unlocked for use with most carriers (except Sprint or Boost Mobile), which gives you more freedom than the locked picks. With a generous 60-day return window and return shipping covered by the seller, you have extra reassurance. Where this one differs from others is in the fine print: it doesn't play with CDMA networks (Sprint, Boost), so make sure your carrier is compatible. You’re not getting the original box—just a generic one—and only a charging cable is included (no wall adapter or SIM). Packaging and included accessories are fairly basic compared to the very top listings. With its long return policy and great seller rep, this is an especially good fit if you want extra time to test things out—but if you demand a flawless out-of-the-box experience or use Sprint/Boost, look at the “Excellent” condition unlocked picks higher up. For everyone else, you’re getting quality and flexibility at a reasonable price.

Why we picked it #10

You’re not going to find an S23 for much less than this. At $169, this is easily the most affordable option on the list—and you’re still getting a device in “Good” refurbished condition, from an established, top-rated seller with a 30-day hassle-free return policy. If you want to keep your upfront costs ultra-low, here’s where you start. The big caveat: this phone is locked to AT&T, so you can’t use it with other carriers. If you’re on AT&T and don’t plan on switching, the savings are great. If not, skip this one—unlocking isn’t guaranteed and can be a pain. Also, since it’s “Good” condition, expect visible wear, and there’s no original charger or packaging (and the listing’s not explicit about whether a charger comes at all). So: if you’re willing to accept cosmetic imperfections, don’t care about missing packaging, and you’re with AT&T, this is the lowest-cost path to an S23. But if carrier flexibility or pristine looks matter to you, you’re better off paying just a bit more for a “Very Good” or unlocked listing further up.

Samsung Galaxy S23

Samsung Galaxy S23: Why Buy Used?

The Galaxy S23 is Samsung's 2023 flagship -- a capable smartphone with the Snapdragon 8 Gen 2 processor, a 6.1" FHD+ Dynamic AMOLED 2X 120Hz display, and a 50MP+12MP+10MP camera system. Now two generations old, it represents outstanding value on the used market with substantial savings over newer models.

What Makes the Galaxy S23 a Great Choice

Every Galaxy S23 has the same core hardware -- the only thing that varies between units is storage capacity. That makes buying used straightforward: you're getting the same phone regardless of who owned it before.

  • Snapdragon 8 Gen 2 processor -- Samsung's 2023 flagship chipset delivers top-tier performance for gaming, photography, multitasking, and everyday use.
  • 50MP+12MP+10MP camera system -- 50MP main, 12MP ultra-wide, 10MP 3x telephoto. Capable of detailed photos and 4K video recording in virtually any condition.
  • 6.1" FHD+ Dynamic AMOLED 2X 120Hz display -- Dynamic AMOLED 2X panel with vivid colors, deep blacks, and smooth 120Hz scrolling. Excellent for media, gaming, and outdoor visibility.
  • 8GB RAM -- Plenty of memory for smooth multitasking and app switching.
  • 128GB or 256GB storage -- Choose the capacity that fits your needs. Larger options command a premium on the used market.
  • 3900mAh battery -- Large battery with fast wired charging and Qi wireless charging.
  • Android 13 + One UI 5.1 -- 4 years of OS updates + 5 years security. Samsung's long update commitment means this phone will receive software support for years to come.
  • IP68 water resistance -- Dust and water resistant (up to 1.5 meters for 30 minutes).
  • Samsung DeX -- Connect to a monitor for a desktop-like experience.

Who Is This Phone For?

  • People who prefer compact phones -- The Galaxy S23's 6.1" screen offers a true flagship experience in a pocketable size.
  • Budget-conscious buyers -- The standard Galaxy S model offers the best value entry point to Samsung's flagship line. As a two-generation-old model, used prices are especially attractive.
  • Most people -- It has a powerful chip, a capable camera system, and all the modern features you need for daily use.
  • Upgraders from older Samsung phones -- If you're coming from an S21 or older, the jump in performance, display quality, and camera capability is significant.

Smart Tips for Buying Used

  • Check Google FRP lock -- A phone with Factory Reset Protection still tied to someone else's Google account is unusable. Make sure the seller confirms FRP is cleared.
  • Verify Samsung Knox status -- Knox 0x1 means the phone was rooted or modified at some point. This permanently voids Samsung warranty and disables Samsung Pay, Samsung Health, and some enterprise features. Knox 0x0 is what you want.
  • Check IMEI status -- Should be clean (not blacklisted or reported lost/stolen). You can check this for free at imeipro.info or similar services.
  • Screen burn-in -- AMOLED displays can develop burn-in over time, especially around the navigation bar and status bar areas. Ask the seller about any ghosting or permanent marks on the display.
  • Battery health -- Samsung doesn't show battery health percentage as easily as iPhones. Check Samsung Members app data if the seller can provide it, or look at battery cycle count. On a two-generation-old device, some battery degradation is normal.
  • Network lock -- Unlocked phones work on any carrier and command a premium. Carrier-locked phones are cheaper but restricted to one network.
  • Look for returns and warranty -- 30-day returns at minimum. Some professional sellers offer 90-day or 1-year warranties. All units are past Samsung's original warranty -- seller warranty matters more.
  • Trust the AI rankings -- Our system analyzes price, condition, seller trust, and return policies to surface the best deals. The top picks represent genuine value.

Frequently Asked Questions

Is the Samsung Galaxy S23 worth buying used?

Yes. Every unit has the same Snapdragon 8 Gen 2 processor, the same camera system, and the same 6.1" FHD+ Dynamic AMOLED 2X 120Hz display -- there's no performance lottery. The only variable is storage size (128GB or 256GB). Buying used saves significantly off the original retail price. As a two-generation-old model, used prices are especially attractive -- you get a Samsung flagship with 50MP camera and 120Hz display for a fraction of the current retail price.

How does used compare to refurbished?

  • Used: Sold by the previous owner. Condition varies -- check the listing carefully for cosmetic wear, screen burn-in, and battery health.
  • Refurbished: Professionally inspected, tested, and cleaned by a seller or authorized refurbisher. Often comes with a warranty and graded condition (Excellent, Very Good, Good).

Both can be great value. Our AI evaluates condition, seller trust, and return policies regardless of the label.

What should I check before buying a used Galaxy S23?

  • Google FRP lock -- Make sure Factory Reset Protection is cleared. A phone still tied to someone else's Google account is unusable.
  • Samsung Knox status -- Knox 0x0 is good. Knox 0x1 means the phone was rooted/modified, which disables Samsung Pay and voids warranty.
  • IMEI status -- Should be clean (not blacklisted).
  • Screen burn-in -- Look for ghosting or permanent marks on the AMOLED display, especially around the navigation bar.
  • Battery health -- Check the Samsung Members app data if available. Some degradation is normal for a two-generation-old device.
  • Network lock -- Unlocked phones work on any carrier. Carrier-locked phones are cheaper but limited.
  • Return policy -- At least 30 days. Many top sellers offer longer.

What's the difference between the Galaxy S23 and the Galaxy S23+ / S23 Ultra?

The Galaxy S23 is the compact, most affordable model in the S23 series. Compared to the Plus, it has a smaller 6.1" display (vs 6.6"), a smaller 3900mAh battery, and FHD+ resolution instead of QHD+. Compared to the Ultra, the differences are larger: no S Pen, no 200MP/108MP camera, and less RAM. But the standard model shares the same Snapdragon 8 Gen 2 chip and core camera hardware -- you're getting flagship performance in a compact, affordable package.

What's the difference between 128GB vs 256GB?

Storage is the only hardware difference between units:

  • 128GB -- The base and most common option. Fine for most users.
  • 256GB -- Good for heavy photo/video shooters or large app libraries.

Our AI factors storage into the value ranking, so higher-storage deals that represent good value will rank accordingly.

Why are prices so different for the same phone?

Pricing varies by storage tier (128GB vs 256GB), network lock status (unlocked costs more), cosmetic condition, screen burn-in presence, battery health, and seller reputation. Our AI analyzes all of these daily to surface the best-value deals.
