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...

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!

Sent from my R800x using XDA App
I am interested in it. I'm trying out the free version (before I buy) but I notice somethings. Maybe its just me but when I watch a movie on the default player on my Evo4G, after tapping on the screen a few times, the lock disables. I can skip through the entire movie and even get out. I'm going to try it with a different player later today.
A few suggestions,
1) It would be nice if the toggle button changed (ex. inverted colors) because when I had the movie problem, I couldn't tell if it was locked or unlocked.
2) Is it possible we can change the location of the toggle button, at least like different corners because it's too close to the home button when in landscape.
One final note, when its locked, you can still drag down the notification bar. So far its looking pretty good. Let me know if I'm doing something wrong since I've only been playing with it for about 30 minutes. Thanks.
Man, this is just what I was looking for ( http://forum.xda-developers.com/showthread.php?t=1431037 ). Super!
I want it for e-reading in kindle or aldiko. Tested so far briefly on Galaxy Tab 8.9 (android 3.2) and an HTC Desire (2.3.3) ... Just fine so far.
I first tried Screen Tools 2, but that one messed up the use of volume buttons for page flipping in both kindle and aldiko.
it took me a while to understand some of the options, like the meaning of "auto on toggle". Also, the toggle app shortcut only works as "on switch" for me... With touch screen disabled, the toggle can't be used to deactivate.
It also took me a while to figure out how to unlock (the use of the tiny toggle button is not documented in the settings or anywhere)
EDIT: I realize now this is what's meant by onscreen button in the settings
The option to leave the edge active is also great, although I will probably opt to switch pages with volume buttons.
EDIT: swiping pages this way works well on the tablet, but is hit and miss on the phone. The edge size may need to be user selectable?
I second the idea to color code the tiny toggle.
Great work.
EDIT: I was searching (Google) for a long time using keywords like "disable touch screen" (all about turning screen off) and "disable touch sensitivity" with no results... Until I found screen tools 2, and then very accidentally this one.
---------- Post added at 01:53 AM ---------- Previous post was at 01:25 AM ----------
Extra feature idea....
disable touch sensitivity along the edge only, keeping sensitivity on the center
Use case: I need something that allows me to hold the tablet a bit more firmly, in one hand, which means putting my thumb in the screen just a bit.

I can add the feature to block edges only, but there is an app called grip it which does just that.
And yes, I should probably use the icon for the status + maybe done kind of animation to tell you when toy unlock vs lock the screen.

After it installs, I can't open it. The screen blinks when I click on the icon, then.... nothing. According to my file manager, the app is running, but I can't access it.
I have the exact same problem with Screen Tools 2.
I tried to uninstall, reboot and reinstall, but it still won't work.

How can I make this work on Galaxy S2? Original 2.3.4 Rom
I have no camera and search button. Where are the settings?
I have installed it, but when I press on it, nothing!
Please help! I need this application!
After buying hardware key support, on my Galaxy S2 the home (and power) bottons still work... even with No Touch active, ofc. Otherwise no problems on my device, also on 2.3.4 ^^.
Also, I absolutly need a popup window on trying to unblock, for inputing a code to unlock, optionaly and maybe only on the payed for version . It is way too easy for my 2 and 4 year olds to unlock otherwise.
Also, I agree, change the color on button when unlocking/locking No Touch.
I would like to be able to choose which tiles on the homescreen to lock. That would be just perfect.
Just tried it and it works nice. I just have one question before I upgrade. If I block the hardware buttons will I skill be able to unlock using a long press of the search key?
is there any chance to make this app lock the screen with long press home button? that would be universal for all android phones. no camera button in my s2. and also so the phone will not respond to any other buttons (ie power button)

Hey,
Could You please modify the upcoming egde kernel so that the screen won't turn on when the home Button is pressed inside our pockets. It would really improve our battery and omit unwanted pocket photos. LG already has it in all their G series, it's a simple proximity Sensor addon. I am asking cause I would like to enjoy edge Features and therefore planning to stay Stock.
Kind Regards,

While I agree with having a option to wake with the home button or not. Use a pattern or password lock screen. You can omit having a camera icon from any lock screen.
That way if your screen does turn on, the likely hood of taking pictures or pocket calls is very minimal.
I use gravity screen app. Keeps phone off in pocket and auto turns it on when pulling it out. Customisable. Great.
You can modify it to disable home button wake. @dwitherell

I'll Sure try it cause what happened to me today was really frustrating, I had my phone in my pockets and after sometime I felt my legs were burning hot so I quickly brought it out thinking the LiPo was about to explode or something but it turned out to be the phone activated the quick camera shortcut on the fingerprint lock screen and started capturing 4k video which for sure heated the processor up and other compnents as well. that was really annoying.
I tried this Gravity app but still I got unwanted phone wakes, I also looked into Rooting and disabling it, but still that's not what I want. I would like to use the home button normally but deactivate it only when in my pocket with the Proximity sensor.
I'm wondering how the feature in the OPO that recognize screen gestures, while the screen of the device is off, actually works? For example, the feature to double tap to awake the phone, or draw a circle to open the camera app. Does the screen really been turned off, or actually the screen is on, and just the screen is black. (this way the screen is on, hence can recognize the gestures, and on the other hand save battery energy).
Thanks!

The display (what you seem to call the screen) is one thing and the touch digitizer is a different thing. The display turns off, but the touch panel stays active and listens for taps/gestures.

Ok, and from development point of view, can one build an android app running on OPO that listens for gestures while the display is off? Meaning allowing the user to define gestures and their actions, expanding the OPO limited fixed gestures and their actions?

I don't think an app can do it. I think (if it is at all possible to add custom gestures) it'll have to be done in the kernel.
here's a small thing I have seen on many phones that have come out in the past year or so that I was taking for granted would exist on the s7, double tapping on the screen to wake it and view your notifications.
its one of the smallest, yet most useful (I feel), little tricks that will save tons of time.
I was hoping it'd be in the "experimental" features the galaxy labs have to offer but nada.
any ideas about getting it on there and/or a way to feed this back to samsung while they still have time to implement this?
re:
"double tapping on the screen to wake it and view your notifications."
Hi
since 7.0 : you can directly go to any of the lock screen, - shown by : AOD - notifications, by clicking on any.
but if AOD is disabled, than there is no way to see them, SO a Xperia z3 like double tap to wake would be appricated

Its on other devices as well. Samsung doesn't really have it because they have physical button where others don't. But yeah, they all should have it
having physical button solves screen turn on comfortability so, why we need double tap? it's additional drain for battery

Seriously:laugh: I said less than 1% to not say 0% and for me, Double Tap is way more convenient than having to press a home button. And u could always turn double tap feature off if u don't like it, i.e, if there was ever a double tap feature!
A 'touch fingerprint button' to wake up & unlock the screen like other Androids would also be great.

being s7's button physical, it's not able to unlock device from deep sleep, at least samsung won't include it if it's even possible and having 2tap2wake will be nonsense at this point... well i dont say it's bad feature, but i just try to explain that Sammy won't include it until we got rear mounted half-physical sensor
The KnockOn feature that LG has would never be nonsense on any phone. It is more convenient than waking with the home button. With the button you have to push a button in a specific place on the phone. With KnockOn you quickly double tap anywhere on the screen.

I love LG's double tap unlock, it is most useful especially during one hand operation with these humongous 5.5in phones. It eliminates fear of dropping phone trying to reach home or power button with 1hand.
As switching off the screen can be a pain sometimes i created this little app to make life more easy
doubleHome is the easiest and fastest way to turn off the screen of your phone!
Turn off the screen from anywhere! Just double tap your home button to turn off the screen.
This app is designed for the latest android versions and supports fingerprint unlocking.
Works with software and hardware buttons and any launcher!
Enjoy!
FEATURES:
Double tap the home button to turn off the screen
Different screen off methods including ROOT
Edge Glow effect
More to come soon
Galaxy S7 users will have to disable double tap to launch camera to get this working i guess.

Among the hardware keys the Power is most effected to be damaged with the passage of time. Thanks for a good application...
Here is my suggestion...
With the screen off feature it get more attraction if you add Power menu or Shut Down menu by pressing three times consecutively the Home button.

Works with my s8plus. Can the same be done for a double tap to wake? That's what I miss. Great amazing work sir
Pretty useful, thanks for share with XDA community.
I'm using root method (Nexus 6p, fingerprint) and I feel that the unlock became slower - I feel the vibration that means the fingerprint was recognized and the screen still black for a second. Is it expected?
Don't work on s7 edge ?
Damn the timeout method doesn't work on my LG g6.
I've tried other apps and no matter how long I set the timer, it doesn't work.
It probably has something to do with the always on display.
Hopefully this thing gets rooted so I can use other methods soon.
Still, great work, it's awesome!
