Re: how to put flash light continuously when device back light is off?

the camera hardware goes into shutdown when the device enters standby mode.

you cannot avoid this presently.


your best bet would be to apply one of the window keepalive settings to your application window. (eg. set SCREEN_PROPERTY_IDLE_MODE to SCREEN_IDLE_MODE_KEEP_AWAKE)


Search around the forums for how to do this, as it varies between libscreen, cascades, air, etc.
