Keep screen turned off function missing from settings.

[Yaf13]

As the title says it. I'm not complaining or anything but I am kinda tired of pushing my lock button 2 times whenever I am in the dark place and want to unlock my phone with KnockON feature (double tap on the screen). Is there a way to get around that "press lock button 2 times to unlock the phone" or it's something wrong with my phone that is missing that setting?
Would be appreciated for an answer.

What phone model do you have? I only have to press mine once to unlock it.

Just increase the screen timeout.

That didn't help. I still can't get it unlocked by double tapping in a dark room.

it's how the phone prevents from accidental unlocks in pocket: when condition is pitch dark, double taps won't work; only with double press the lock button and fingperprint sensor.

Thanks for the explanation but I was wondering if I can disable that function just for ease of use. Btw fingerprint unlock won't work in the dark either for some reason.
