LG G3 camera auto opens on screen unlock

I've owned the G3 for about 9 months now and it's been great up until recently, when i swipe unlock the screen, the camera often opens straight away and i have no idea why, i don't have lockscreen shortcuts and i've disabled the long press for camera on the rear buttons, and there's no shortcuts for it on my main screen when unlocked, does anyone know what the issue is?
