SELL YOUR ONEPLUS OPEN
A OnePlus Open pays between $97 and $583. Where you land in that range is decided by wear and by whether everything still works, so five minutes of checking before you post it is time well spent.
Most people call it a trade-in. We call it a Buyback, and the difference is what happens after you mail it. We wipe it to Department of Defense standards. We track it the whole way. We tell you what we found, in writing, before any money moves.
Now the part that is specific to this phone. The Open has two screens and the one you actually live on is the outside one. At 6.31 inches the cover display is a normal phone shape, so most Opens spend the day shut, being used like any other phone. That outer screen is the one collecting pocket scratches. It is also the one most likely to hold a faint ghost of the status bar, because it is the screen showing a status bar all day.
Both screens count for grading. A crack in either one puts the phone in Faulty, and either one can burn in. Turn the brightness up, put a plain white image on the inner screen in a dim room and look for a shadow of the clock or the navigation bar. Then fold it shut and do exactly the same on the cover screen. Most people check the big screen and never think to check the small one.
The line down the middle of the inner screen is the crease. It came with the phone. The Open was built to fold and the crease is what folding looks like, so do not mark yourself down for it. It is not damage, we do not treat it as damage, and it does not cost you a cent.
If you are working out where to sell a OnePlus Open, or hunting for the best place to sell a used or broken one, we quote both. Shipping is free in both directions. A phone that will not power on we cannot buy, because we cannot test it and we cannot clear your data off it, but we will recycle it for free and wipe it on the way.

HOW IT WORKS
Pick your storage and the grade that matches the wear. Check both screens first, the outer one as carefully as the inner one, and work the hinge through its full travel. Most two year old Opens land on Average. The Buyback price you accept is held for 14 days.
We email you a prepaid USPS label. Sign out of your Google account, erase the phone, then fold it shut and box it with something soft around it. Keep the case, the charger and the box. None of them are priced in and they only risk going astray.
Your Open 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.

ONEPLUS OPEN BUYBACK QUESTIONS
It depends on wear and on whether everything works. A 512GB Open with light wear you cannot feel with a fingernail is $456, and that is where most two year old ones land. Tidier than that and it is $485. Heavy wear you can feel takes it to $291, and a cracked screen or a dead hinge is $97. Run the quote at the top of the page for the exact figure on yours.
No. Every book style foldable has one and the Open's is shallower than most, which is why some owners only notice it when the light catches it. It is the point the screen bends at. We expect to see it on every Open that arrives and it does not move your grade. Run a fingernail along it if you want to be sure of what you are feeling: a shallow dip that runs the full height of the screen is the crease, and a hard edge or a step you can catch a nail on is a crack, which is a different answer.
Yes, and it grades Faulty, which is a price rather than a refusal. A 512GB Open in that state pays $97. Worth saying twice: both displays count. A crack in the little outer screen does the same thing to the grade as a crack in the big inner one, and so does a chip anywhere on the frame or the back. Pick Faulty when you quote and nothing changes when it reaches us.
Test it before you decide. Open the phone all the way and hold it up so the screen faces you. The two halves should sit in one flat plane with no bend left in the middle. Now fold it shut. It should close with the halves flat against each other along their whole length. If it no longer opens flat, or no longer shuts properly, the hinge has stopped working, and anything on an Android phone that has stopped working grades Faulty. A little sound as it opens is normal and is not a fault on its own.
Both, and burn-in is an automatic Faulty, so this is worth five minutes. Turn the brightness right up, find a dim room, and put a plain white image on the inner screen. Look across it for a faint clock, a navigation bar or the shape of an app you leave open. Then fold the phone shut and repeat on the cover screen, which is the one people forget and often the one that has been showing a status bar all day. Two things that are not burn-in: a single stuck pixel, and a color shift you only see when you tilt the phone.
Good means light wear that you cannot see from arm's length. Above that, Flawless means no marks at all, and Brand New means sealed and never activated. Below it, Average is light wear you cannot feel with a fingernail, and Fair is heavy wear you can feel but with no cracks and no chips. Faulty covers anything cracked or chipped and anything that has stopped working. Grade it the way it looks in daylight, not the way you remember buying it.
No. There is no battery percentage rule on any Android phone we buy, so there is no health screen to go hunting for and no number to report. The only way the battery affects your Open is if it has genuinely stopped working, and that is caught by the same rule that covers everything else that does not work. If it holds a charge and the phone runs, the battery is not costing you anything.
They are close cousins and easy to mix up. Read the back and the model number. A OnePlus Open says OnePlus on it and carries the model number CPH2551, which you will find on the inside of the SIM tray and in Settings, About device. An Oppo Find N3 is the same hardware sold under Oppo's name with a different number, and it needs its own quote rather than this page. If the number on yours starts with PHN, you are holding the Oppo.
The Open was sold in the US as 16GB with 512GB, and that is the version almost everyone here has. A 1TB Open is an import, and it is not carrying a price with us at the moment. Quote it anyway. The tool shows the live figure and the table on this page moves with the feed, so if that changes it changes here too.
We cannot put a price on that one, and the reason is practical rather than fussy. A phone with no power cannot be tested, so we would be guessing at what we are buying, and your data cannot be cleared off it, which we are not willing to skip. What we will do is recycle it for nothing, on a free label, with the same Department of Defense wipe we give everything else. Want it back instead, that is free too.
Not while there is a balance on it. A phone sitting under an installment plan or a lease is still tied to somebody else, and we do not purchase devices under financial obligations. Settle it, own it outright, then come back and quote it as normal. Nothing else about the process changes.
We have to turn it down. A Google account lock or an FRP lock means the phone cannot be set up by anyone but you, so it cannot be resold and we cannot buy it at any grade. The fix is in your hands and takes a minute: sign out of your Google account, then erase the phone, in that order. A phone reported lost or stolen, blacklisted or blocked by a carrier is the same answer, and that one we cannot fix for you.
No. Nothing has to be in the box. The case the Open came with, the 67W charger, the cable and the retail packaging are not priced into the quote, so sending them adds nothing and only gives them a chance to go missing. Send the phone. Fold it shut, wrap it in something soft, and let the box do the rest.
Read both numbers before you decide, then pick. Carrier offers on foldables tend to arrive as bill credit spread over two or three years and tied to a new line, so the money is not really yours and it is not available now. Ours is cash, and on a 512GB Open with light wear it is $485, held for 14 days while you think about it. If your carrier beats that in real money you should take it. We would rather you did the arithmetic than took our word for it.
Four ways, and you choose at checkout. 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, with PayPal's own 2.99 percent fee coming off. A bank transfer takes 2 to 4 days and a check in the post takes 3 to 5. Whichever you pick, it goes out the same day your Open clears inspection. One exception: a sealed phone graded Brand New is paid through PayPal only.
Pick your storage and your grade. It takes about a minute, and we hold the number for 14 days.
