1. Back Up Your Data – You may already have your phone setup to automatically sync to an online service like iCloud or your Google account. We have learned you can never be too careful with data and think it’s a good idea to make a manual backup of the data on your phone as well. You can create a backup using the tools provided by your phone’s manufacturer, such as Apple’s iTunes, Samsung’s Kies, or theWindows Phone Desktop App.
2. Perform a Factory Reset – The reset will wipe the phone, deleting your personal data and any apps you’ve installed. It will also reset the phone back to its default state. Each operating system handles this a little differently:
3. Change Account Passwords – For extra protection, change important passwords (e.g., your Apple or Google account) that you may have saved to your smartphone. The factory reset of the phone should remove any saved passwords along with your data, but we recommend clients take this extra precaution. You may also want to ensure that your phone is removed from any services, like Find My iPhone via icloud.com, or as part of the two-factor authorization in your Google Account if you set it up.
Once you complete these three steps, your phone will be ready to safely leave your possession.
