KnockOn app brings double-tap to lock to most Androids. and wake to ones with OLED displays
If you think that LG's Knock Code feature to lock and awake the screen with two taps in quick succession instead of fumbling for buttons is awesome, then you'll be delighted to know that you can have it on your non-LG phone, too. Provided that you have a phone with an AMOLED display, that is, as the tap-to-wake function doesn't work with LCDs.

Anyhow, the app does what it advertises - when you tap two times in a quick succession on an empty homescreen space it locks your phone, and when you double-tap on a locked screen it wakes it up (AMOLED only). In everyday usage this has proven to be somewhat faster and more convenient than finding and pressing a physical side or home key. We've already shown you how to do the tap-to-lock thingy on any Android without root, but the process is somewhat convoluted, requiring a paid NOVA launcher, and the Greenify app.

Of course, an app like KnockOn isn't without bugs and kinks, but on most phones with AMOLED panels both gestures seem to work well. With the paid Pro version you can set both actions at once, or customize the double-tap speed.
