This tutorial is for people who’re forfeiting their Gmail inboxes during sales. Gmail.com is very strict on new logins, and transfers can be very, very painful. To limit possible problems, it’s advised that you follow our instructions and make sure your inbox is disconnected from your device. What can happen if you don’t disconnect your device? The worst-case scenario is you lose your inbox, forever (happened before). This will null and void the transaction, and you will be left without a payment or your inbox. So, we encourage every seller to follow our directions so transfers go by smooth.
How to remove Gmail from your phone?
When you remove an account from your device, everything associated with that account is also deleted from your device. This includes email, contacts, and settings.
- Open your device’s Settings app.
- Tap Accounts. If you don’t see “Accounts,” tap Users & accounts .
- Tap the account you want to remove and click Remove account .
- If this is the only Google Account on the device, you’ll need to enter your device’s pattern, PIN, or password for security.
Note: Settings can vary by device. For more info, contact your device manufacturer.
