This is so far the best setting for me. The only thing is doesn't turn off automatically ,I have to press the right side button to turn it off. I'll try with 20 seconds to see how that works .Yeah looks like Standby is constantly ON
Try this instead (if you want)
In Settings > Standby > Display
And if Automatically is checked turn OFF Motion To Wake.
That was it only lights up if you touch the phone instead of coming on when you move.
