DEFECTIVE - Samsung Galaxy S20 5G - 128GB - Gray - GSM Unlocked - 11999
Used
Why we picked it #1
If you want the absolute lowest price for a Galaxy S20, this is the cheapest option on the list. You're getting all the core features—speedy performance, great screen, expandable storage—for a fraction of what this phone cost new. But there are some serious tradeoffs here: the rear camera doesn't work, the battery is quite worn, and the sale is final with no returns. This is a phone for you only if you rarely or never use the main camera, and are comfortable with a heavily used device that may need a battery replacement soon. If you want a backup, a device for non-camera tasks, or are very tech-savvy, it could be a steal. But if you use your phone for photos or want even a basic safety net for returns, I'd pay a bit more for something less risky—there are options not much higher priced that offer a working camera and return window.
Samsung Galaxy S20 5G Unlocked 128GB SM-G981U Cosmic Gray Poor Used
Used
Why we picked it #2
You're getting a fully unlocked Galaxy S20 that's been inspected, sanitized, and ready for use on most carriers—a solid, straightforward buy. It even comes with a USB cable, which is a bonus at this price point. Compared to the top pick, this does cost more, but unlike that one, all key functions (including the camera) are expected to work, and there's no 'final sale' risk—though do double-check the return policy. The big tradeoff? There's a cracked backdoor, so it'll look rough and offer less protection, but the front screen should still serve you well. If you want a Galaxy S20 that's reliable and actually usable for daily photos, this is a balanced pick—worth considering over cheaper, more compromised options, so long as you don't care much about cosmetic flaws.
SAMSUNG GALAXY S20 5G SM-G981U (UNLOCKED) 128GB Cloud Blue Light Screen Burn
Used
Why we picked it #3
This listing is for you if you want to keep your costs low but still have a working phone with all the main features; it’s noticeably cheaper than refurbished or “excellent” options on the list. You get a factory reset device, a clean IMEI, and all major functions tested, plus it comes with a third-party charger. The catch is screen burn-in and a battery at about 80% health—it’ll show visible marks on the display (especially on white or light backgrounds), and you should expect less-than-stellar battery life. Both are livable if you aren’t picky about visuals or plan to keep the screen brightness low. If you value price over perfection and don’t mind the screen flaw, you’re getting strong value here. A step up in condition (with no screen burn) is available—but you’ll pay significantly more.
Samsung Galaxy S20 5G SM-G981U (UNLOCKED) Smartphone 128GB Cosmic Gray VERY GOOD
Very Good - Refurbished
Why we picked it #4
You're paying a bit more here than for other used devices, but you're getting the reassurance of a 'Very Good - Refurbished' phone with a clean IMEI and no screen burn-in—both big wins at this age. All main functions have been tested, it’s sanitized before shipment, and you get a third-party charger included. On top of that, the seller has a stellar feedback record, so you can buy with confidence. The battery is decent for a six-year-old model, but keep in mind that it's not new—don't expect all-day power without charging. If you're willing to spend a little extra for the peace of mind that comes with a solid refurb and seller rep, this is a smart pick. Compared to the cheapest deals, you're getting more reliability and less risk.
Samsung Galaxy S20 5G SM-G981V (UNLOCKED) Smartphone 128GB Cloud Blue VERY GOOD
Very Good - Refurbished
Why we picked it #5
This is another "Very Good - Refurbished" S20, priced the same as the prior listing and offering much the same: clean and sanitized, all main functions tested, battery in reasonable shape for its age, and the basics (wall adapter and USB cable) included. The big difference is it ships quickly (next day handling), so if you want your phone fast, that's a bonus. It does arrive in a generic box, which matters only if packaging is important to you—it doesn’t affect the phone's quality. For just a bit more than the rougher used options, you’re getting reliability and a clean experience. This stands shoulder to shoulder with the other “Very Good” refurb above: pick based on your color preference or whichever listing inspires more trust.
Samsung Galaxy S20 5G Cosmic Gray 128GB Unlocked - Good w/ LCD Burn In
Used
Why we picked it #6
This is a very affordable S20 with all the core specs you expect, but be aware of its downsides: you’re getting a phone with noticeable screen burn-in—which means faint ghost images or discoloration are present, especially against lighter backgrounds. There's also no box or accessories, so you’ll need to supply your own charger. That said, if you just need a phone with decent performance and don't mind the visual flaw or lack of extras, this is still a step above the absolute cheapest options: there’s no mention of camera failure or serious defects, and you're not locked into a final sale. If the screen isn’t a dealbreaker and you’re handy with sourcing chargers, it’s a budget-conscious pick. For a better screen and restored accessories, look a little higher up—but expect to pay more.
Samsung Galaxy S20 5G SM-G981U 128GB Cosmic Gray T-Mobile Unlocked W085483
Used
Why we picked it #7
This listing offers a low price—great if you want to spend as little as possible—but the tradeoffs pile up here. There’s screen burn-in, which is common at this price, but also two tougher issues: the back is lifting (which could expose internal parts to dust or damage) and there’s a black spot on the screen. So you're facing both visual blemishes and a compromised build. While it’s still an unlocked Galaxy S20 with all the fundamental talent—speed, display, cameras—it’s best for you if you’re DIY-oriented or looking for parts, not a pristine daily device. If you can stretch your budget, other listings get you fewer defects and greater peace of mind, but for the lowest upfront price with full disclosure of issues, this is at least honest about what you’re buying.
SAMSUNG GALAXY S20 5G SM-G981U (UNLOCKED) 128GB COSMIC GRAY (LIGHT SCREEN BURN)
Used
Why we picked it #8
You’re getting a Galaxy S20 here with the important upside of a third-party charger included, so you can start using it right out of the box. The price is middle-of-the-pack, but you're trading off for a visibly used device: the screen has light burn-in and the battery sits at about 80% health, meaning it won’t last as long between charges—expect to top up more often. The burn-in shouldn’t interfere with most tasks, but you’ll spot ghost images or color shifts on light backgrounds. If you’re focused on function over form and need a complete kit (no need to hunt for a charger), this could be an easy low-hassle option. If you’re especially picky about the display or battery stamina, you may want to step up to a “Very Good” refurb—they cost more, but you get a cleaner experience.
Samsung Galaxy S20 5G G981U (Verizon Unlocked) 128GB Cloud White (Excellent)
Excellent - Refurbished
Why we picked it #9
If you want a Galaxy S20 that feels as close to new as possible, this is your splurge pick. You're getting an 'Excellent - Refurbished' phone with no screen burn, third-party charger, a clean look, and—crucially—a one-year warranty that brings major peace of mind. It's ready for Verizon and other compatible networks, and includes little extras like a SIM remover tool. The price is the highest here, but you’re paying for a lot less risk and maximum confidence in condition. Downsides: no original box or accessories, and battery health isn't specified (typical for older phones), so you may still need to plan for some battery wear. If protection against future headaches matters most to you, it can be worth paying up for this pick. Otherwise, if you’re OK with some cosmetic or screen flaws, you’ll pay far less elsewhere.
Samsung Galaxy S20 5G G981U Unlocked Mint T-Mobile Verizon Straight Talk Boost
Excellent - Refurbished
Why we picked it #10
This listing is at the top in price, but you get an 'Excellent - Refurbished' S20 with a genuine Samsung charger—which is rare among these options. Despite the mint condition claim, there are important caveats: this phone has screen burn-in, carrier compatibility quirks, and you won’t get a SIM card or ejector tool. There’s also no guarantee of water resistance. If you want a nearly-new feel and care about original charging accessories, this is one of the few ways to get both. Just be ready to set up your carrier’s data/MMS manually if needed, and to live with some minor screen imperfections. For not much less, you could grab a still-very-good S20 with no burn-in or compatibility hassles, and probably won’t miss the OEM charger. Pay up for this if original accessories and top refurb quality are your priorities, but otherwise you might find better value-for-money elsewhere.
