samsung galaxy s6 clear view case - Clock ?

[KarenLorr]

Hi

I have the samsung galaxy s6 (not the edge) with the Samsung clear view case.

When I close the case a clock shows for a few seconds then goes off.

Is it possible to get the clock to stay on somehow.

I used to do this with my old nokia N8 and I found it really good but I can't work out how to do this with the new Samsung G6. I have downloaded a clock app which works - but this also closes when I shut the case cover.

Thank you
