I've just discovered the disconnect between SmartLock and Android Pay - and the last Android Pay update broke it completely for my LG V10.
My setup:
- LG V10, secured with fingerprint and PIN
- Microsoft Band 2, set as Trusted device in SmartLock
- Citi MasterCard, apparently an "approved" AP provider
Before the January update, I was able to tap and pay, but with a little weirdness - unlock the phone with fingerprint, open Android Pay, make sure Citi is default card, tap terminal... the phone would vibrate
multiple times asking for PIN (even though provider is "approved"?), enter PIN, tap terminal again, green checkmark pops up.
After the update, I would follow the same procedure, holding the phone up to the terminal, but instead of asking for the PIN, it would get stuck on the black "Hold phone to terminal" screen, vibrating every other second, and never prompting for PIN. After pulling the phone away from the terminal, it would back out to the card screen, and the cashier would say that it never processed. Reattempting the tap gets the same result, and this was with multiple merchants where Android Pay worked before.
I setup a support request with Google, which was a complete waste of time. The email response was:
The specific error message that you saw means that your device can't support Android Pay's advanced security. If you've heavily modified your device, may I recommend returning it to its original state and trying again? Otherwise, you may want to use Android Pay on a different device for the most secure payments.
Really? A device that worked fine before, now is suddenly insecure? Replying to the email with more detail (my V10 is stock, this worked before, using fingerprint and PIN) got me a response asking me:
Please reply to this email if you are still experiencing difficulty after clearing the cache and cookies of your device, please also include screenshot of the action that you're trying to perform. We'll be happy to investigate further for you.
Cookies??? A screenshot of the "Hold phone up to terminal" screen??? Again, waste of time.
After checking this forum (and this post as well!) I tried disabling SmartLock... went to BestBuy, tapped to the terminal,
instant checkmark, just like in the ads. No multiple vibrations, no prompt for PIN, just tap and done,
like it's supposed to be!
Given this, Google really needs to get their act together when it comes to Android Pay. I used Wallet on my Nexus; only one merchant in my area accepted NFC payments then, and it was a breeze - unlock with PIN, tap, done. I stopped using Wallet when I switched to Windows Phone, but now than I'm back on Android, Android Pay is a convoluted mess by comparison.
Moral of the story? Don't use SmartLock with Android Pay. Lose one convenience to gain another.
