The exact amount depends on the Samsung Galaxy Z Fold4's condition, storage capacity, carrier lock status, and whether security protections (like Find My Device / Factory Reset Protection) are removed. ecoATM gives an instant cash offer at the kiosk and you can get a price estimate online before you go. Many customers find ecoATM's instant-cash offers are competitive and can beat typical carrier trade-in values, but the final price is set by the device's specifics.

Start by getting an online quote on ecoATM's website so you have an estimated value, then prepare your phone (back up your data and sign out of accounts). Next, bring the Samsung Galaxy Z Fold4 to a nearby ecoATM kiosk (they're located inside Walmart and other major retailers); connect the device at the kiosk so it can run a quick diagnostic. Finally, review the instant offer the kiosk displays and accept to get paid instantly or decline and keep your phone.

Yes — ecoATM accepts Samsung Galaxy Z Fold4 devices with cracked screens, dents, faulty batteries and other damage, but condition will lower the offer you receive. ecoATM will still evaluate the device and make a cash offer when possible. If the kiosk determines there is no resale value, ecoATM will recycle the device responsibly so materials stay out of landfills.

Yes — ecoATM accepts carrier-locked Samsung Galaxy Z Fold4 phones, though locked devices typically receive a lower offer than unlocked ones because they have more limited resale options. A carrier-locked phone is one that can only be used on a specific wireless provider until it's unlocked. ecoATM will still evaluate locked devices and make a competitive cash offer based on the phone's condition and market demand.

Before you sell, back up any photos and data you want to keep and sign out of accounts on the Samsung Galaxy Z Fold4. Disable Factory Reset Protection / Find My Device, remove your SIM card, and perform a factory reset so the phone is clean for the next owner. Arriving at the ecoATM kiosk with the device reset and ready speeds the diagnostic and offer process.

You should factory reset your Samsung Galaxy Z Fold4 before selling to remove personal data, and ecoATM recommends doing that as part of preparation. ecoATM also performs additional data wiping and secure handling on devices before resale to protect customer privacy. Together these steps help ensure your data is removed to industry-standard practices before a device is resold.

Devices in good condition are refurbished and resold, extending their useful life and keeping functional electronics in circulation. Devices that can't be resold are recycled through certified e-waste partners so valuable materials are recovered and toxic components are kept out of landfills. ecoATM participates in large-scale device reuse and recycling efforts to reduce electronic waste.

The trade-in value of your Samsung Galaxy Z Fold4 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 Fold4 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.
