How do I turn on double tap to wake on my Nokia Lumia 635?

[Windows Central Question]

I went to display+touch but still can't find it...

Update to WP8.1 (should be actually 8.1 out from the factory) and after that you'll find Glance screen options under the settings

Edit: go to settings > touch > Wake up > On

I might be wrong. But I know on my backup 635 it does not have double tap to wake nor does it have anything but a vibrate selection for the navigation keys. You cannot even select higher sensitivity for the touch screen like you can on even the low end 520. Good phone; but they left out many things to get the price down. Glance screen is not available on the 635.

That feature is not on the 635. likely because the phone lacks a proximity sensor which would be used to govern activation. (so it won't double tap in your pocket for example)

I'm 99,9% sure double tap has nothing to do with proximity sensor (it activates even when tapping the lower part of screen which surely isn't close enough to the prox sensor and also requires actual physical taps) and pretty sure not with glance either.

I can assure you that both glance and the double-tap-to-wake features are tied to the proximity sensor.

Should you cover the proximity sensor, double tapping anywhere on the display with not function. (phone thinks its in a pocket or place where its not in use, thus ignoring double-tap inputs)

If its uncovered, double tapping anywhere on the display will work, regardless of where on the display the taps occur.

The sensor simply serves as a "should I be enabled now?" check.
