How to wake the screen just by tapping the android screen

0

It would be possible to wake up a device with Android Operating System just touching your screen, without pressing any physical button like Power or Home, such as Nexus 5 and LG G2 in which a double tap on the deleted screen awakens them.

I need something already existing that performs this procedure because I do not know how to proceed. I leave a link for a Youtube video demonstrating the feature in more detail.

Not a conventional Android feature, but a modified ROM called ElementalX. In the video description there is a link to the from this ROM to Nexus 5 ( doubletap2wake functionality). This functionality even consumes more battery power when enabled, since the device's CPU does not enter sleep mode shortly after the screen goes off, having to be active to detect the onscreen taps.
