Update Your Mobile 1-Click
1-Click on your mobile device is a separate feature from the 1-Click Shopping which you use on your computer. Mobile 1-Click must be turned on directly from your mobile device.
To update your Mobile 1-Click from your mobile device:
Launch the Amazon App.
From your Android device, tap the three horizontal bars in the upper left of the home screen and then Your Account
From your iOS device, tap More on the home page and then Your Account.
From your Windows Phone, tap Your Account from the home page.
Tap 1-Click Settings.
Tap the provided address under Delivery Address and Payment.
Choose a default address and payment method.
You can go to Manage Addresses and 1-Click Settings
on your computer to view your Mobile 1-Click settings once you've switched it on. You'll see a box in the upper right-hand corner labelled Mobile 1-Click
that will display your device name or number and provide a button to turn off mobile 1-Click if you wish.
