I've been messing around with the various White Noise settings to see if I can fix this, but I'm completely stumped. Basically, I have white noise on all night on my iPhone 4 which means I usually put it on charge at some stage. But the screen lock doesn't work on charge with White Noise running in the background, regardless of whether I switch to home screen (with background audio going) or whether I leave it on the White Noise screen. The screen goes dim, but never switches off completely. Does anyone have a fix, or is this an iPhone problem, not an app problem?
Any help much appreciate.
