Just switched back to Android from being on iOS for three years. I got my V20 on the 24th of December. I've pretty much gotten it setup the way I want, but I have a question regarding Android pay on this phone. Is the only way to activate from the lock screen by holding it to a compatible terminal? The reason I ask is that with Apple pay I could double tap the home button to bring up the app on the lock screen. This would allow me to switch between cards or select a reward card for the cashier to scan. Is this possible, or do I have to unlock the phone and go into the app itself in order to do these things? Any advice would be greatly appreciated.
