After seeing a lot of comparison videos of the HTC One m8 and the Galaxy S5 I realized one of the big things HTC has is their motion launch gestures. Unfortunately for HTC it is limited to doing just a few things. So since the Galaxy S5 has an OLED screen which is turned "off" when displaying black pixels, I figured I could create something like the motion launch gestures that uses minimal battery.
So I created Knockr an app that allows users with OLED Screen devices, like the Samsung Galaxy S5 and Moto X, to quickly enter an app with gestures without having to turn the screen on.
Gestures include:
Double Tap: Double tap the screen to open any app you choose or unlock the screen
Swipe Up, Down, Left, Right: Users can set each Swipe to open a separate app or unlock the screen
Long Press: Long press the screen to open any app you choose or unlock the screen
Volume Up when in Landscape: Pressing the volume up button when the device is in Landscape will automatically open the camera
I am still working on improving some of the things in Knockr, but wanted to post it on here to get some feedback and suggestions to make it better.

**EDIT**
The newest update 2.1 now includes Knocks. Knocks is like LG's Knock Code. You can create multiple Knocks to unlock or open apps.

Going to give it a try with my Galaxy S4 Mini, I hope it's not too harsh on the battery. Nevertheless this application seems like a great idea, Thank you.
EDIT: Seems to work very well. Just a few things I noticed.
-The screen can turn on by a single touch to the screen (it will then display lockscreen)
-The backlight keys turn on after the app is activated once the screen is locked (the keys are only on for a few seconds on my phone anyway, no big deal)
-Is it possible to decrease the delay between when the phone is locked and when the Knockr app is loaded/active?

You said that this is for screens with OLED yet someone commented checking whether it would work with their S4 Mini. Now I thought that S4's had AMOLED which was different, if I'm mistaken, does this mean that it will work on my S4-19505?
Thanks, it looks brill by the way.
Nandish-
AM-(OLED) your device has an OLED display. It only works with OLED type screens cause they use no power to produce black screens.

Only one touch and the screen is awake to show the lock pattern on Samsung S4.
What an awesome app! My only recommendation is to take away the one tap to turn on the screen, as the screen can accidentally turn on in your pocket very easily and cause unwanted battery drain.

Thanks for the feedback. It shouldn't use much battery especially if you use the power management since you probably wont have your phone turned off to often outside of your pocket during the day and if you do you can just turn it over and still get the same benefit.
I have already uploaded a new version that has removed the single tap action so there aren't any false touches registered. It also made the screen on an option to choose for any of the gestures. It also fixes a bug that cause Knockr to close when the orientation was changed after being pocketed.
Unfortunately I don't think there is a way to load Knockr any faster since I already have it setup to load as fast as possible. The problem is that I have to use a broadcast receiver to receive the screen off and the broadcast takes a little bit of time to be sent out (I'll keep looking for ways to make it faster though).
Really cool app!
Few recommendations:
1. Any way to show clock and notifications every couple of seconds? (Ex 15s)
2. Way to bypass knockr when power button is pressed.
Thanks!

awesome app
awesome app.
but there is delay while unlocking phone (or performing any action while screen is locked).
i don't know it is because of my s3 or app
but cool idea.
one more suggestion screen should be unlocked after pressing power button.
mind blowing app.
works great.
thanks for this and keep going on.
it is really nice idea.
questions :
can it detect multi finger on screen off? we might get more gesture thts why only.
screen segmentation? means on some part of screen it detects then that gesture recognized.
just some ideas.
Awesome app. Just awesome. I didn't want to install a custom kernel just for this feature and now I don't have to. Working great at the moment. Power button is no use for unlocking but app is working with almost no hitch.
A suggestion for people who use this. Install screen on&off from play store and add that to nova launcher's double tap gesture to lock the screen. Now you can use double tap to both locking and unlocking.
Also, I have to swipe twice to open an app. Can't we do that with one swipe?
Edit: It opens with one swipe but it isn't always working. Needs some work.
Bug
found a bug :
proximity sensor always on for me on stock 4.4.2 Note 2 N7100.
whether i check power management or not.
App works on Galaxy S3, only that the proximity sensor thing for pockets, it isn't very accurate. I kinda cheated to test it, covered my sensor, then swiped left to try to launch camera, and it did. I didn't want my camera to be turned on and heating my phone in my pocket during school

I don't have a OLED lcd panel but I decided to try it. is it because I don't have a OLED panel that the screen shows black with 2 navigation buttons on it? And if that's the reason is there a way to make it work on TFT panels?
I am having this issue with my Verizon Moto X. Does it need any extra settings?
It installed on Galaxy Nexus (It is having SUPER AMOLED), when I double tap, screen wakes but shows black screen.
Cool app!
I can see navbar when i turn screen off though. And i can press power button and turn device off...
Im using a n7000 running Slimkat

Hey! This works very nicely! I'm having no problems so far. However, on my stock 4.4.2 Samsung Note 3 N900W8, I've noticed that if I have Multi Window on (use two apps at the same time), the multi window tab shows on the screen when Knockr becomes active. Specifically, I turn off my screen using the power button, and a second or two later the tab pops up. I don't know if this can be prevented without turning multi window off entirely, but thought I'd bring it up. Great app!
By interface I mean the lock screen icon and any custom info that has been set. For example I have time remaining, time etc in the top corners. The only workaround is to switch on-off the screen with a hardware button, and the device will leave lock mode.
Using the last pro version in a Samsung galaxy 10.1 2014 but this issue is already several month in.

I can reproduce it. But, there is no need to screen off & on to unlock. Just touch the screen again. It will show lock button (not other custom Settings). You can easily unlock it to show the interface again.
BTW, you can fix this issue by simply adust the settings
Open Settings > Player > Lock Screen & set it to mode 3.

Hi. I'm new to Nova Launcher. I have a Samsung phone and I'm using Nova to replace "Samsung Home Experience" which I guess used to be Touchwiz. One of the things I don't like about the Samsung Launcher is that my home screen is sensitive to long presses to the very edges of the screen. I can't disable that. So it's easy to long press by accident at the edges of the screen with your hand when holding the phone. When you do, the home screen switcher mode is activated. Then you have to press screen to bring home screen back to top. Annoying.
One of the the reasons I became interested in Nova launcher is because you can lock the home screen. So I did that. However, whenever a long press takes place on the home screen, a message stating the screen has been locked pops up... Can I disable this notification since I know that the screen is locked since I set it this way? This way my hand won't set off the notification, just like it did with the home screen switcher? Thanks.
maybe an answer can be found here https://forum.xda-developers.com/showthread.php?t=1389071
On my Samsung S8, I had a feature, so when I had auto-rotation locked, if I physically rotated the phone to a landscape position, a little phone icon with a padlock appeared in the button bar on the bottom. Pressing this icon, would manually rotate it to landscape.
I loved that feature, because I think auto-rotating is irritating, and having to manually unlock and lock rotating when I want to manually landscape the phone is irritating.
However, sadly my S8's battery started popping and swelling and become cracks in the backplate.
So had to ditch it and buy a Note 10.
Now to the question: How I do to enable this feature on Note 10?
good lock navstar

On my note 10+ the icon appears when I move the screen. Back and forwards. But it disappears quickly, so I have to rotate once more.
Would me nice if it staid longer in that right corner.
See no settings however.
This is enabled by default
Hi there . I've been using a Galaxy S10 for the past 3 years. When I flicked open the cover, it went straight onto the home screen, without ANY lock screen, not even swipe.
I did disable the lock screen on this Xiaomi 12T, but I still can't get rid of a screen that requires me to swipe before I get to my home screen. How can I get rid of it?
Thank you in advance!

Not possible and this prevents an app from accidentally launching.
Damn . Since I have a cover with a latch, apps accidentally launching are a non-issue
Another case of product design which sacrifices customization in the name of "saving the majority".
Ouffff. Anybody know any workaround? Other than rooting the phone
No workaround,without rooting and this remains to be verified, except maybe with an AOSP rom.
I believe in the extended settings/ developer options (to activate hit several times miui version in detailed cell phone overview from settings) it is possible to deactivate lockscreen.
