It totally breaks the home screen UI and requires a restart.

Comment 2

[Preeti Raghunath(:Preeti)]

Moving to 1.5 as NFC is not a feature included in the de-scoped feature list.

Greg, Could you please take this bug? Thanks.

[Greg Weng [:snowmantw][:gweng][:λ]]

This concerns to disable any homescreen and other actions that break the NFC sharing sessions (except the poweroff key pressing). I remembered that I discussed this with UX, and may provide a patch to review next week.

Set target milestone. If you can not make it, please update it. Thanks.

I can't reproduce this bug on new master. Although that my device is not a truly NFC device, but I triggered the same event to let it into the shrinking mode.

Can Walter check this bug again?

The video.

And I've tested it on the Nexus 5, the result is the same.

After discussed with Walter, the issue is:

1. Press home to make the foreground as background app
2. Trigger shrinking UI at this stage
3. The shrinking UI should not be triggered, but it was and would break the homescreen.

This bug blocks NFC 2.0 release.
