The exact amount depends on your Samsung Galaxy Z Flip4's condition, storage size, carrier lock status, and any active security settings like Factory Reset Protection. ecoATM gives an instant cash offer at the kiosk (and you can get a price estimate online first) and in many cases the cash offer compares favorably to carrier trade-in routes. Because condition and settings change value, the kiosk runs a quick diagnostic before showing the final offer. You can accept or decline that offer right away.

Start by getting an online quote on ecoATM's website, then prepare your Samsung Galaxy Z Flip4 by backing up data and removing accounts and the SIM. Bring the device to an ecoATM kiosk in a retailer near you, connect it for the kiosk's diagnostic check, and review the instant offer the machine provides. If you accept, ecoATM pays cash immediately (or another offered payout method); if you decline, you keep your phone.

Yes — ecoATM accepts Samsung Galaxy Z Flip4 devices with cracked screens, dents, faulty batteries, and other damage, though visible or functional damage will reduce the offer. If the kiosk cannot make a cash offer for resale, ecoATM will ensure the device is recycled responsibly. Selling a damaged device at ecoATM still helps you recover value and keeps the device out of landfill when it can't be reused.

Yes — ecoATM buys both carrier-locked and unlocked Samsung Galaxy Z Flip4 phones, but carrier-locked devices typically receive a lower offer than unlocked ones because lock status affects resale value. A carrier lock means the phone is tied to a specific mobile network and may limit future buyers, which is why the offer can be lower. ecoATM will still run diagnostics and make a competitive offer based on the phone's overall condition.

Before you go to an ecoATM kiosk, back up any photos and files, sign out of your Google account and Samsung accounts, and disable Factory Reset Protection if applicable. Remove your SIM card and any microSD, then perform a factory reset so the device is cleared of personal data. Arrive at the kiosk with the phone powered on and able to connect so the machine can complete its diagnostic and give you an accurate offer.

You should factory reset your Samsung Galaxy Z Flip4 before selling to remove personal data, and ecoATM also performs additional secure data wiping on devices before resale. ecoATM follows secure data-handling practices on all devices to protect sellers and buyers. Taking the simple step of signing out of accounts and resetting the phone gives you the best protection.

Devices that can be repaired or resold are refurbished and resold, extending their useful life and keeping them in circulation. Devices that cannot be resold are recycled responsibly through ecoATM's recycling partners so hazardous materials are kept out of landfills. Selling to ecoATM helps recover value from the device and reduce electronic waste.

The trade-in value of your Samsung Galaxy Z Flip4 isn't fixed — it's based on factors like storage capacity, physical and functional condition, and whether the device is carrier-locked or unlocked. ecoATM gives you an instant cash offer at the kiosk (paid in cash or via Venmo/PayPal where available) rather than store credit, so you can see what your Samsung Galaxy Z Flip4 is really worth before you commit. Start with an online estimate, then complete a quick on-site diagnostic at a kiosk to lock in your final trade-in value.
