:se:Not sure if this is old news as I have only just found out about it

Torch is a java app. for the k800/k790 and works by activating the red led next to the flash. (you can exit by pressing backbutton)
Be sure to change the permission for the app. to "Multimedia" = No, or you will get a question about access to the camera every time you start Torch.
(highlight Torch in Applications > press More > select Permissions > select Multimedia > select No)
IT WORKS! I've just put it on my phone and it is really cool!!
