Any way to turn the screen off on the lock screen?

I prefer not to shimmy up the phone to reach the power button, and have it set up so a double tap on the back key turns the screen off. However, they do not shoe up on the lock screen. So I have to enter the pattern then turn the screen off. Does anyone know a mod or widget you can place on the screen in the lock screen to turn the display off?
Thanks

Viper ROM has that sort of option. I don't use Xposed, but I believe it does as well.

If you're willing to flash a custom kernel, Evolution's kernel has swipe to sleep feature (swipe right to left on the bottom of the screen to turn it off, works on lock screen.)

If you are using the stock LockScreen, double tapping anywhere on the display will turn the screen off. If you are using a replacement LS you can get an Xposed module that turns the screen off with a double tap on the status bar.

[APP][4.1+] Knockr - Lockscreen

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!

screen turns off on lockscreen

When I turn the screen on to check notifications and i expand a notification: text, facebook message, etc..
Even while my finger is touching the screen the screen turns off. This occurs both in power save mode and with power save mode turned off.
Its quite annoying, especially if i just want to read real quick what an email says.
Anyone else getting this?

Nope. Try doing a hard reset

Tried a second s6 and resetting the device. I get the same thing. I also have the unlock effect turned off.

My phone is also giving me problems on the lockscreen. I don't have an unlock effect either so I'm thinking be the problem. I notice when I turn on any other option my problem goes away. It just darkens my wallpaper to almost black. Did a hard reset as well.

I also noticed a huge lag when i tap a notification and then try to unlock. I'm also unable to double tap a notification on lock screen to open that specific app.
I tried using the buble unlock affect and still get the same problem. turn on screen->expand notification of given app while still holding my finger on the screen, then seconds later screen turns black

I see what you're saying about holding the finger on the screen and it still times out. Is it not like this on other lollipop phones, this is my first go with lollipop so I don't know? ...No lag for me, and I can tap then unlock and I'm in the app asap.

Well maybe its cause i came from an AOSP rom on my Lg g2 but i would think if your finger it touching the screen it should stay on anyways.
I wish i could just double tap the notification and it opens the app versus tapping the notification and then having to swipe to unlock.
the lag when trying to unlock after tapping the notification is a little, its not instant like how it would when tapping on a heads-up notification

I just tried again...If you swipe down on the notification to read it, it should go up to like another screen (not literally) but the notification slides up basically were the clock and weather would be. There it doesn't time out until the screen time out you have set under display is reached, and you can read the other notifications too. What you are doing is pulling down the notification without letting go then it times out. Swipe the notification and let go of the screen.

double tap to wake the screen

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

it'd be great if we didn't have to have AOD to get that considering how simple and awesome of a feature it is...

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.

Why do we need the Home button's force/3d touch?

I'm playing s8+ for over a week. Slowly the first dust settles down and I start thinking about the phone in a more reasonable way. One day I was using an app that allows rotating screen 180° (*). My first thought was: what will happen with the home button when it will be on the other side of the screen?
Will the force touch work?
It doesn't of course.
So will I be able to launch the assistant app? Yes. It launches when you keep your finger on the home button a bit longer.
Ok then. So I asked the question myself:
What this force touch is made for?
The only use I find is: enable use of Home button in immersive mode (On the AOD screen you need to double click to "turn on" the screen so I can't say that the force touch is necessary there).
Any other use you find for this sophisticated tech?

It's just to show off when the screen is off, and Always on Display is off (I don't use it due to it being a waste of battery) and allows someone to turn on the screen without using the power button.

Is just f'n awesome straight up bragging rights when you tell your friends that I can turn my phone on by touching the invisible button lol that's my only reason for needing it

I love the feature.... no screwing around with power button or anything just press and hold to unlock:good:

The only uses are turning on your screen from a screen-off state, and to return to home straight away when the buttons are gone. You can force-touch the place where the home button would be when the home buttons aren't there to go straight to your home screen, pretty useful when playing full-screen games. And it's super easy to unlock your phone when you set the touch sensitivity to the highest, just a small touch unlocks the screen easily

Heres a tip: If you leave the home button on with the always on display, you can also double tap it to have it open the lock screen instead of unlocking.

Why do people keep saying this? Is there some feature I'm not aware of? It's a hard-press or, in the alternative, a double tap if the home button is showing. I've never seen any option to "press and hold" (a/k/a "long-press") like you and others keep saying. What am I missing?

go to display settings then to navigation bar settings then there is option for unlock with home button, once that is on, with AOD on you just touch and hold the button and it will go right to your home screen or you can shut off AOD and with the screen off you can still press and hold in the same area where the home button would be and it will unlock the phone and take you to your home screen:good:

Strange. That doesn't work for me. I enabled "Unlock with Home Button," and when my screen is on AOD, I touch-and-hold on the home button, and nothing happens. Only double-touching or hard-pressing do anything. I'm on Verizon S8+.

Main use is for AOD. You wouldnt want your phone turning on simply be the home button screen area being rub.
But outside of that. There isnt a need for it. There had been phones with on screen home buttons before. This thing here is that they disapper when using full screen on the s8
