If you’re planning to sell your phone, performing a factory reset is one of the most important steps you can take before handing it over. A factory reset erases all of your personal data — including contacts, photos, apps, passwords, and account information — and restores the device to the same state it was in when it left the manufacturer.
Why You Should Factory Reset Before Selling Your Phone
Skipping a factory reset puts your personal information at risk. Even if you delete files manually, traces of your data can remain on the device. A factory reset ensures a clean slate for the next owner and protects you from potential identity theft or unauthorized access to your accounts.
If you’re selling your phone to a buyback service like Gizmogo, completing a factory reset before shipping is strongly recommended. It speeds up the inspection process and ensures your quote isn’t affected by data-related issues.
How to Factory Reset an Android Phone
To factory reset an Android phone, follow these steps:
- Open the Settings app on your Android device.
- Scroll down and tap System.
- Tap Reset options.
- Select Erase all data (factory reset).
- Review the information on screen, then tap Erase all data to confirm.
- Enter your PIN, password, or pattern when prompted.
- Confirm again to begin the reset.
The device will restart and the reset process will complete automatically. This may take a few minutes.
Note: The exact menu names may vary slightly depending on your Android manufacturer (Samsung, Google Pixel, OnePlus, etc.), but the path through Settings > System > Reset options applies to most Android devices.
How to Factory Reset an iPhone
To factory reset an iPhone before selling it, follow these steps:
- Open the Settings app.
- Tap General.
- Scroll down and tap Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- Enter your passcode or Apple ID password when prompted.
- Tap Continue.
- Follow any remaining on-screen prompts.
- Tap Erase iPhone to confirm and begin the reset.
Your iPhone will restart and restore itself to factory settings. The process typically takes a few minutes to complete.
Tip: Before erasing, make sure you’ve backed up any photos, contacts, or files you want to keep — either to iCloud or to your computer via Finder or iTunes.
What Happens After a Factory Reset?
Once the reset is complete, all personal data is removed from the device. The phone will boot up as if it’s brand new, displaying the initial setup screen. You do not need to complete setup — simply power it off and it’s ready to be sold or shipped.
