A factory reset can help with troubleshooting or prepare a device for resale, but it may remove local data and app settings. The risk is not just forgotten photographs. It is losing the one device that approves your account sign-ins. Plan the move before pressing the reset button.
Confirm your backups are usable
Check that important photos, files, notes, contacts and application data are backed up somewhere you can actually access. Open a few sample files on another device. Some apps store information only locally or require a separate export, so do not assume the operating system backup captures everything.
Move sign-in and recovery methods
Review authenticator apps, passkeys, backup codes and recovery phone numbers for essential accounts. Some credentials sync securely; others need an explicit transfer or re-enrolment. Confirm you can sign in from another device before wiping the old one, especially for email, banking and work services.
Unlink the device where appropriate
Follow the manufacturer’s steps to sign out, remove activation locks or ownership associations and disconnect smartwatches or other paired devices. For managed workplace hardware, contact your administrator rather than resetting it without permission. If selling the device, check that it is no longer tied to your personal account.
Use official reset instructions
A reset may differ from a simple restart or network-settings reset. Read the relevant official instructions for your model and software version and keep the device powered appropriately. Avoid unofficial tools that request your account password or claim to remove security locks.
Check the result before handing it over
When selling or recycling hardware, confirm that personal data is erased using the manufacturer’s supported process and that the setup screen no longer exposes your accounts. Remove SIMs and memory cards if applicable, and dispose of batteries and electronics through suitable local recycling channels.
