But with patterns here
How it works ?
Divide your screen vertically and horizontally , you get four divisions
They are numbered as
1 | 2
-----
3 | 4
The pattern is stored in sysfs file sys/android_touch/tap2unlock_pattern
You tap the right combination to open your screen
Pressing the power button will turn your display on but not the touch sensor.

version 3.0
-Disable t2u by default.
-Fix reboot security vulnerability.
-Remove many security vulnerability
-Finally it can be a reliable daily lockscreen driver
version 2.0
-You cant view your pin from sysfs file
-You cant change your pin without tap2unlock app (v0,2 is a must)
-You dont need to press pwr button then pattern and attend call 
-Incoming calls (and only that) is allowed without entering your pin
-After the call your phone will go to touch freeze(if u havent entered ur pin to attend call)

version 1.0
-Ability - 4 number pattern
-[STRIKE]Currently the pattern gets restored to 1234 after every boot(can be solved by init.d workaround)[/STRIKE]
(download the appfrom 2nd post)

-keeping your phone facedown will suspend touch sensor , so needless to worry about battery drain during nights or when within ur pockets
-deep sleep will work even when its on

Many credits to showp-1984 for his D2w which made this possible.

Want this for your phone ?
Post a link of this thread to your kernel developer .

have a moto E?
http://forum.xda-developers.com/moto-e/orig-development/cm11-0-kernel-alpha-kernel-0-1-t2931985

It required heavy commitment, testing and hardwork give credits if you use it , press thanks it encourages



Download the Application for T2u Control in the second post

Note : even during a call u have to press power button , pattern then open to attend call


Video description :

Message for kernel control application developers and kernel developers :

If you would like to provide support to this feature , i can help you with whatever details you want to.
There is patch files provided below for convenience git apply it , --author="goutamniwas <[email protected]>"(this assumes u have already implemented dt2w and s2w , if not u wud be required remove some lines after imlementing the patch

if u use this in ur kernel source u are very free to use it (giving credits is optional) -any support will be provided


developers - If you have a working kernel with t2u for ur device notify me , so that i add it here

https://github.com/goutamniwas/Tap2unlock

Screenshots :

Instructions :
-Download the latest version of the app(if u have already have installed previous version, just download apk and install)
-Push it to your system/priv-app/ and set permission rw-r-r
(or) Flash the flashable zip
-Open the app use the t2u on/off button once , and set a new pattern(default oldpin is :1234 )

T2u Control Application :

Download v0.6 apk
OR Flashable zip (v 0.6)
Download v0.5(push it to system/priv-app)
OR Flashable zip (v 0.5)
Download v0.4(for t2u v2.0 with call fix commit )
Download v0.3(for t2u v2.0 and above)
Download v0.2(for t2u v2.0)-not recommended
Download v0.1 (For t2u v1.0)

what can the app do ?

version 0.6(stable)
Fixes
-Failing to load the lockscreen at occassions
-Taking too much time load the lockscreen.
-Awkward looks
-Screen freezes some times.
-problems on lockscreen load after phonecalls.(sometimes screen appearing b4 incoming call)
changes
-compatible to t2u 3.0
-Prevent app getting shown in recent appslists(its a lockscreen afterall)
-Fixed all know securit glitches
-T2u is now a daily lockscreen driver 

version 0.5(major upgrade)
-Fix a lot of bugs
-Fix t2u getting off after an incoming call sometimes.
-Now u can pattern with ur screen ON also
-After attending an incoming call you are shown a screen to input pattern

version 0.4
-No screen freeze whatsoever during calls
-Fix t2u switch settings not getting set after boot
-Now u cant mess up with pattern inputs as the app checks if ur pattern and entered data
is valid b4 accepting it.
-when u havent used the t2u switch once with the app , t2u switch sets to default 0 (untested)
-when u havent set a new pattern with the app , t2u pattern is set to default 1234 by the app now (untested)

version 0.3
-Fix screen freeze after outgoing call.
-Now the t2u switch(on/off) is also set at boot time in addition to the pattern
-New icon

version 0.2
-Integrated working with t2u 2.0
-Leave security to kernel
-Allow incoming call without entering pattern
-Pattern can be changed only if u know the old pin
-Freeze touch after incoming call if u havent pattern unlocked it 

version 0.1
-switch on/off t2u
-change pattern
-set pattern on boot(takes some time though)

The kernel mod is currently available for :

Motorola Moto E

Alpha kernel -thread link

Motorola Moto G

Felcia kernel -thread linkby @Shuttwind215

Notify here if you have added t2u to your device .
If you want support for your device , find a kernel developer of ur device's forum and notify him about this thread,request him kindly

hope for kernel control apps to support this sooner....
.
any way init.d can work this out??

 

[eloko]

So is like patern-pin unlock but without turn on the screen?

Probably if you personally copy your init.d statement in it , so everytime it sets ur default pattern

So is like patern-pin unlock but without turn on the screen?

we do this double tap 2 wake and then a pattern , so its like combining it wake+unlock

 

[AshuGite]

Probably if you personally copy your init.d statement in it , so everytime it sets ur default pattern

as screen is divided into 4 regions which yields mostly 24 combinations so if we define a numeric code to each one it can be set easily...

Adding echo "4letter-pattern" > sys/android_touch/tap2unlock_pattern to init.d file will do it

okay that's good...then there is not a great need for an app to do it.... BTW very good implementation...

New video description !!

i have made a video to describe how it works and how to change the pattern

 

[ChinmayKunkikar]

Hello!
Awesome work!

Is this similar to the LG G3's Tap Code?

Sent from my Xperia Sola using XDA Premium 4 mobile app

 

[syedtahir16]

This is awesome. Thank you

 

[matmutant]

@goutamniwas : looks great :laugh:, but what about trying to make a .ko module instead, that end-user could insmod at will (via init.d?) and that wouldn't require any kernel modifications ?

 

[EasyGoingXD]

@ak Kernel for the OnePlus One would be awesome if you would work together with him :angel:

@goutamniwas : looks great :laugh:, but what about trying to make a .ko module instead, that end-user could insmod at will (via init.d?) and that wouldn't require any kernel modifications ?

Its not possible as we need edits with the device's touch , proximity and display drivers

@ak Kernel for the OnePlus One would be awesome if you would work together with him :angel:

Pm him the link to this thread

 

[manups4e]

hi ^^ i was looking it to cherry-pick it into my kernel repo.. but ^^ this "Currently the pattern gets rstored to 1234 after every boot" prevents me from doing it ^^ mmm i was thinking.. you could check the LG G3 kernel sources for some improvements with their knock code

as the post says the users need to edit their init.d for their own pattern , otherwise we need an application level support

 

[manups4e]

mmm understood thank you well anyway if you want to take a look at the G3 knock code you can download kernel sources here don't know if it could help ^^ but i hope so

I dont think if they have implemented it through kernel , probably they did it with an application ???

a github link wud be appreciated and useful

I would second that. To think this further: If you make a module, you could also do a flashable zip for this. In the flashable zip, you could use aroma to let the user set his/her code initially. Changing the code could be done by aroma again. Just an idea.
