Sell your ZenFone 8 for cash

Average is where most used ZenFone 8s sit, and it means light wear you can see but cannot feel with a fingernail. A 128GB in Average pays $85 and a 256GB pays $94. Clean it up a grade to Good and the 256GB becomes $108. Run your own one through the quote tool at the top of the page for the exact figure.

Wired headphones, something with clear vocals, volume at about half. Play it and listen to the left ear on its own, then the right. Both should be present and equal.

Then wiggle the plug gently in the socket while it plays. Crackling, cutting out, or sound that only holds when you push the plug in a certain way all count as an audio fault, and an audio fault grades the phone Faulty. Same answer if the socket is packed with lint and a plug will not seat properly. It is the one hole on this phone that goes straight inside, and on a five year old phone that has lived in pockets, it is the first thing to fail.

Look at the front and the back. The ZenFone 8 has a small hole-punch selfie camera in the top corner of the screen and a fixed camera bar on the back. The ZenFone 8 Flip has no front camera at all, because the rear camera unit motors up and swings over the top edge to face you, and it is a noticeably bigger phone at 6.67 inches. If the camera on yours moves, you have the Flip, and this is not the right page for it. Also worth knowing: the Flip has a moving part, so on that model the motor working is part of the grade.

Yes. A crack or a chip anywhere, front, back or camera lens cover, means Faulty regardless of whether the phone works fine. That pays $20 on a 128GB and $22 on a 256GB. Pick Faulty at the quote step. The whole point of grading yourself honestly is that the price you accept is the price we pay.

It can, because the panel is a Super AMOLED. Display a plain white image at full brightness and look for a faint permanent shape: the status bar across the top, the navigation bar at the bottom, or the outline of a keyboard. Tilting the phone often makes it easier to see. Burn-in grades the phone Faulty, even if the screen is otherwise perfect and undamaged, because a permanent mark cannot be resold as a clean display.

Good means light wear that you would not notice holding the phone at arm's length. Flawless above it means no marks at all. Average below it means wear you can see but not feel with a fingernail, and Fair means heavy wear you can feel, with no crack or chip anywhere. The fingernail is the test rather than your eye, because eyes are generous and fingernails are not. Drag one slowly across the screen and around the frame edges: anything that catches counts.

Then it is Faulty. The Android rule we work from is a single principle: if something on the phone does not work, the phone is Faulty. That takes in the power and volume keys, the under-display fingerprint reader, both microphones, the speakers, the USB-C port and both rear cameras. Testing all of it takes about two minutes and it is worth doing before the quote rather than after.

It does not. There is no battery percentage rule on Android phones here, so there is no health screen to find and no threshold to clear. A 4000 mAh battery in a small phone gets worked hard and will have faded, and that is expected rather than penalized. The only battery that changes your grade is one that has actually failed, which is caught as a functionality fault like anything else.

No. Nothing beyond the phone is required. The 30W charger, the bundled case, cables and the original packaging are not priced into any grade, so including them adds nothing to your payment. Keep them, or pass them on to whoever gets your next phone.

Not for money. A phone that will not power up cannot be tested, and your data cannot be cleared off it, so putting a price on it is not something we will do. Free recycling is the alternative and it is a real one: same prepaid label, a DoD-grade wipe when it lands, and proper disposal. Prefer to keep it, and we will send it back at no cost.

Only once it is paid off. While a balance is running, on an installment plan or a lease, the phone is under a financial obligation and we do not purchase devices under financial obligations. Settle it and it quotes like any other ZenFone 8, no waiting period beyond that.

No on both counts. A Google account lock, which you might see called FRP, blocks the purchase at every grade, and clearing it is on your side: sign out of the account and erase the phone before it goes in the box. The IMEI is the separate check, and it has to come back clean. Reported lost or stolen, blacklisted or carrier blocked all fail, and we return the phone rather than buy it.

ASUS sold this phone unlocked and direct in the US, so the table above is the unlocked pricing and it applies to virtually every ZenFone 8 in the country. Choose unlocked when you quote, whatever network the SIM in it belongs to. Nothing in our carrier pricing for this model pays above these numbers.

Not usually, and often they will not take it at all. Carriers put their money behind the handsets they sell in volume, and ASUS phones were never that in the US. When an offer does exist it tends to be bill credit spread over 24 months rather than money, and only if you stay on the plan. Ours is a single payment the day the phone clears inspection, in whichever form you pick. Get their number and compare. If theirs is higher, take it.

Erasing: open Settings, then System, then Reset options, then Erase all data. Sign out of your Google account before you run it, since that is the step that lifts the lock. Photos, messages and saved passwords are erased and cannot be recovered. Our erase your device page has the walkthrough.

Payment: gift card, PayPal, bank transfer or check, chosen at checkout. Gift cards come out roughly 3 percent ahead because the brands add a bonus. PayPal is instant with PayPal's 2.99 percent fee. Bank transfer is 2 to 4 days, a check 3 to 5. Everything leaves the same day inspection clears, and a sealed Brand New phone is PayPal only.
