Not even low light mine works in.. and your face has to be too close to the screen for it to work..
Doesn't seem to work from regular viewing distance for me..
Same issue on Note4 so I just disable that crap...
Eye-scrolling is crap.. swipe to pan is crap.. crap crap crap
Only direct call makes sense to me.. and even that is slow as hell... it's faster I just press call. lol
