Double tap to wake up and glance view stopped working.

[Stylazation]

As the topic says, the glance view and double tap stopped working after shutting down there phone and leaving it in charge. Turned back on noticed that some features like glance view, double tap to wake up, vibrate on tap wouldn't work. Fixes vibrate on tap by turning off and on again, recalibrated phone still the glance view and double tap to wake up isn't working with screen time out being 1 minute and it dims and turns off in seconds.
Any one know this problem or a fix may be. Kindly put your effort and thoughts I to the topic thank you.

You have to have one of the lock screens turned on to use it I believe even if its just the swipe to unlock
