Hi Ansar,

First, can you please clarify how this issue manifests? I suspect that when you lock the screen, you can at least see the Smart Lock icon next to the password field. Is that correct?. If so, does hovering your mouse over the icon provide any information via a tooltip?

The logs of your feedback report include the line: "Updating screenlock state from [phone locked and rssi too low] to [phone not lockable]". This suggests to me that your phone does not have a lock screen -- is that correct? If so, setting up a lock screen on your phone (e.g., a PIN or Pattern to unlock) should resolve your issue (please confirm).

Thanks,
Ryan
Thanks Ryan, after enable PIN on phone, i can unlock the device with smart lock.
Hi Ansar,

Glad to hear that helped. While you were having this issue, did your Chromebook display the following text? [1] (It's a bug if it did not): 

"To keep your Chromebook safe, Smart Lock requires a screen lock on your phone."

Even if this is displaying correctly, it's possible we may need to adjust this string to be more explicit.

No i didn't see that message.

I just reproduced this scenario on 11151.17.0 (as well as HEAD), and confirmed that the message "To keep your Chromebook safe, Smart Lock requires a screen lock on your phone" does correctly show.

I suspect real issue at hand here is the significant latency of Smart Lock (it took over 10 seconds for the message to display while the Chromebook scanned for my phone) leading to a confusing user experience. It's also possible you clicked anywhere else on the screen, dismissing the tooltip message before getting a chance to read it.

Even though everything seems WAI here, the UX could clearly be improved -- at the very least, we have plans in the future to improve latency. Hopefully the UI can be revisited as well.

Closing as WAI.
