Hi all,
Additional use case may be, taping your mobile for nfc payment or nfc ticketing confirmation, without having to unlock your screen.

I actually think this is a great idea! This must be a MAJOR UX no-no when it comes to users watching content or working with content. My use case is looking at a recipe and having two hands covered in cake mix and then the device screen going off and I have no idea what to do next because I can¹t see the recipe anymore! Further than this, some people might watch videos and like to read comments (for example) at the same time.

Does anyone else think that this kind of API would be useful?

Thanks! Natasha
