Android Pay is here in the UK now and I have started using it for the first time. I have successfully made a few payments but I find I need to open my S-View case for it to work. I don't need to unlock the screen but that screen needs to be on. I can't get it to work simply by pressing the power switch and light up the windowed screen when the case is closed. Is that how it works on the Note 4 (or other S-View case-equipped phones)? Or is there a trick to get it to work without opening the case or even having to power it on (from standby). I got the impression that on a typical Android phone it should work when the phone is in standby. Help and answers very welcome! I'm running Marshmallow, if that's of any relevance.
