SELL YOUR GALAXY S25 PLUS
A Galaxy S25 Plus is worth between $73 and $465 today, with every step between them printed in the table below. Storage is half of that spread, because this phone was sold as a 256GB and a 512GB and the bigger one is worth more at every step. The rest is wear, and on a Galaxy S25 Plus most of the wear that moves your number is on the screen, which is why the next few minutes are worth spending.
Worth separating two things people treat as the same errand. Your carrier's version happens at a counter: you drive to a store, you wait, somebody looks at the phone for about as long as it takes to fill in a form, and the offer exists only while you are standing in front of them. A Buyback happens at your kitchen table. You run the white screen test below in your own dim room, at your own pace, and the postage is prepaid in both directions, so if the inspection finds something you missed, the Galaxy S25 Plus comes home without costing you anything to get it back. Nobody here is waiting on you to decide today.
Your Galaxy S25 Plus has a sharper screen than it has been showing you. The panel is QHD+, 3120 by 1440, and Samsung ships it set to FHD+ out of the box. Open Settings, tap Display, tap Screen resolution, and move it to WQHD+.
Do that before you grade the phone, because the screen is where two of our Faulty rules land. Any crack or chip in the glass is Faulty, however well the phone works. Screen burn-in is Faulty too, and every Galaxy S has an AMOLED panel, so burn-in is a real risk on this one rather than a theoretical one.
Here is the test, and it takes a minute. Turn the brightness all the way up, go somewhere dim, and fill the screen with a plain white image. Now look straight at it. What you are hunting for is a faint permanent ghost of something that never moves: the Always On Display clock, the three navigation buttons at the bottom, the status bar icons across the top. If you can see one, that is burn-in and the phone grades Faulty.
Two things that are not burn-in. A greenish or bluish cast when you tilt the phone is how AMOLED panels behave off-angle, and it goes away when you look at the screen straight on. One dead pixel is not burn-in either, though it is still a fault. Do not grade a healthy Galaxy S25 Plus down over either of those.
That resolution setting also settles one identification question quickly. If Settings, Display has a Screen resolution row, you are not holding the small one. The 6.2 inch Galaxy S25 has no such row, because its screen is FHD+ and there is nothing to switch. The Galaxy S25 Edge is the phone this test will not settle for you, because it carries the same 6.7 inch QHD+ panel your Plus does. Count the rear cameras instead. The Edge has two. Yours has three.
Unlocked handsets pay the most on this model, at every grade and both storage sizes. The grid below is the unlocked price, and AT&T, T-Mobile, Verizon and anything else sit under it in every cell. Pick the carrier you actually pay a bill to, because we check the lock when the phone arrives.
We buy used Galaxy S25 Plus handsets and we buy broken ones. Sell your Samsung Galaxy S25 Plus for cash here and shipping is free in both directions. The one we cannot buy is a Galaxy S25 Plus that will not power on, because a phone with no power cannot be tested and your data cannot be cleared off it. Send that one in anyway and we recycle it free, or mail it back to you free.
LIVE PRICES
The used resale value of a Galaxy S25 Plus runs from $73 for a cracked 256GB up to $465 for a sealed 512GB. Most phones land above the middle. A used 512GB in Good condition is $405.
What you can sell yours for comes down to three things: storage, wear, and whether it is carrier locked. Every number below is pulled live from our own price feed.
| Comparison row | 256GB | 512GB |
|---|---|---|
Brand New | $405 | $465 |
Flawless | $405 | $465 |
Good | $365 | $405 |
Average | $343 | $381 |
Fair | $219 | $243 |
Faulty | $73 | $81 |
HOW IT WORKS
Pick 256GB or 512GB, then your carrier, then the grade that matches the wear. Run the white screen test first, because burn-in is the one fault on this phone you can look straight at and still miss. To find your carrier, search your settings for SIM lock. If it says the phone is unlocked, choose Unlocked. If not, choose the carrier you pay. The Buyback price you accept is held for 14 days.
A prepaid USPS label arrives by email. Before you box the phone: remove your Google account, remove your Samsung account, turn off Find My Mobile, then factory reset it. Take your SIM card out and leave the empty tray in the phone. Keep the charger, the cable and the case, because none of them are priced into your quote.
Your Galaxy S25 Plus clears inspection within 48 hours of landing with us. If it matches what you told us, the money leaves the same day, by gift card, PayPal, bank transfer or check. Every phone gets a Department of Defense grade wipe whether we buy it or recycle it, and we tell you what we found either way.

GALAXY S25 PLUS BUYBACK QUESTIONS
Storage, wear and the carrier lock set the number. An unlocked 512GB in Good condition is worth $405. That same phone in Average condition is $381. A 256GB with a cracked screen is $73. Use the quote tool at the top of this page for your exact one.
No, and the difference shows up in your bank account. A trade-in is what a carrier or Samsung runs. Your old phone comes off the price of a new one, and the value reaches you as credit, usually dripped out over a two or three year contract.
A Buyback is a straight purchase. We buy the Galaxy S25 Plus, you keep your carrier and your plans, and the money arrives as a gift card, a PayPal transfer, a bank transfer or a check. Put both numbers next to each other before you sign anything.
Open Settings and tap Display. If there is a Screen resolution row, you have the Plus. The 6.2 inch Galaxy S25 does not have that row at all, because its panel is FHD+ and there is nothing to change. The screen size is the other giveaway, 6.7 inches against 6.2. The certain answer is in Settings, About phone: a Galaxy S25 Plus reads SM-S936U or SM-S936U1. If yours turns out to be the smaller phone, its page carries its own prices.
Count the rear cameras. Your Galaxy S25 Plus has three. The Galaxy S25 Edge has two, and it has no 3x telephoto, so there is no 3x button in its camera app. Both phones carry the same 6.7 inch QHD+ screen, which is what makes people second guess it, but the Edge is 5.8mm thick and 163 grams while the Plus is 7.3mm and 190 grams. Pick one up and you know. Model numbers settle it: SM-S936U for the Plus, SM-S937U for the Edge.
Burn-in grades the phone Faulty. Every Galaxy S has an AMOLED panel and an AMOLED panel can keep a permanent shadow of anything that sat in one spot for months on end.
Test it properly. Set the screen to WQHD+ in Settings, Display, Screen resolution. Brightness to maximum. Go into a dim room and fill the screen with a plain white image. Look for a faint ghost of the Always On Display clock, the navigation buttons, or the status bar icons. Any ghost you can see means Faulty. On a 512GB that is the gap between $405 at Good and $81 at Faulty, so it is worth the minute.
Yes. Any crack or chip puts the phone into Faulty, and that covers the screen, the back glass and the camera lens covers. It applies even when the phone works perfectly, which catches people out. Faulty is a price, not a refusal: a cracked 256GB pays $73 and a cracked 512GB pays $81. Choose Faulty at the quote step and nothing changes when the phone reaches us.
No. There is no battery percentage rule on a Galaxy S25 Plus, and there is no battery health screen for you to go hunting for. You may have read about an 80 percent rule on an iPhone page. It does not apply here.
What does apply is the general rule on this phone: if something on it does not work, it grades Faulty. A battery that will not hold a charge through a morning, or that cuts the phone off at 30 percent, is a battery that does not work, and that is how the battery reaches your grade. A battery that just is not as good as it was on day one is normal wear and changes nothing.
The rule is broader than people expect, so it is easier to learn as a principle than as a list. If any part of the phone does not work, the phone is Faulty. A dead speaker, a mic nobody can hear you on, a button that has stopped clicking, a fingerprint reader that will not read, a camera that will not open, a charging port that only works at one angle. Any of those, on their own, and the grade is Faulty.
Then there are the faults that cost you the grade even though the phone is working: any crack or chip, screen burn-in, an aftermarket or replaced display, and an engraving. Choose Faulty when one of those is true and the price you see is the price you get.
Then it is Faulty. The reader on a Galaxy S25 Plus is ultrasonic and it sits under the glass, so it can fail without leaving a single mark on the outside of the phone. Lock the screen and open it with your thumb three times before you choose a grade. If it misses every time, or if the phone has quietly gone back to asking for your PIN, that is a functionality issue and it grades Faulty. The same goes for face unlock.
Yes, and unlocked wins on this model at every grade and both storage sizes. An unlocked 512GB in Good condition pays $405. The same handset locked to AT&T pays $289. To check yours, search your settings for SIM lock. If you are not sure, choose the carrier you pay a bill to. If you tell us it is locked and we find it unlocked while we are processing it, we raise your offer without being asked.
That one we cannot buy. Without power we cannot test the phone and we cannot clear your data off it, and we are not going to put a price on something we have not been able to check. Free recycling is the offer instead. Post it on a free label, we destroy the data to Department of Defense standards, and we dispose of the handset properly. Would you rather have it back? That return is free too.
Not while there is money owed on it. A phone still running on a carrier payment plan or a lease counts as being under a financial obligation, and we do not purchase devices under financial obligations. Clear the balance, own the Galaxy S25 Plus outright, then quote it like anything else.
No. A locked phone is one we cannot buy at any grade and any price, so it is worth clearing all of this before you post.
Google FRP has to be off. Remove your Google account from the phone first and factory reset it second. In the other order, the next owner is stopped at the setup screen and the phone comes back to you.
Samsung's reactivation lock has to be off as well. Turn off Find My Mobile and take your Samsung account off the phone.
The IMEI has to be clean. Reported lost or stolen, blocked by a carrier, or carrying an unpaid balance all fail that check.
A Galaxy S25 Plus with a tripped Knox counter is also one we cannot buy. Knox trips the first time a phone is rooted or flashed with custom software and it can never be put back.
Order matters. Take your Google account off first, in Settings, Accounts and backup. Then take your Samsung account off and turn off Find My Mobile. Then open Settings, General management, Reset, and choose Factory data reset. Your photos, messages and saved passwords are erased and they cannot be recovered. There is a walkthrough with pictures on our erase your device page. We run a Department of Defense grade wipe on arrival too, but yours needs to come off first so the phone is not locked when it lands.
You choose the method when you accept the quote. A gift card is emailed and works out about 3 percent better than the rest, because the brands add a bonus on top. PayPal is instant and PayPal charges a 2.99 percent fee on it. A bank transfer takes 2 to 4 days and a posted check takes 3 to 5. Whichever you pick, it goes out the same day your phone clears inspection. One exception: a Brand New sealed Galaxy S25 Plus is paid through PayPal only. Worth knowing on this model, Brand New and Flawless pay exactly the same, so a phone you opened and looked after loses you nothing and can still be paid all four ways.
Pick your storage, your carrier and your grade. It takes about a minute, and we hold the price for 14 days.
