Not responsible... As is.. Bricked devices... You've read this thousand of times. 
Hope everyone here is understanding what he does.

Introduction

This is Unlegacy-Android kernel with some extra features that I added/enabled for personal use and decided to share in case someone else like them too.
I've done all I wanted by this moment so probably I am not going to continuously develop and improve this kernel if there will not be such necessity.
If somebody wishes to co-work or continue, I am all for it. Sources are open.

Features

Code:
Any bugs/features are the same as on Unlegacy-Android stock kernel except those listed here.

Color control

Allows to adjust display colors (really?).

You need to use third party app like "Trickster MOD" (Requires root) to edit it.

Touch wake and Proximity wake

Old cool feature reworked and improved by me.
Allows to wake device by touching screen and/or proximity sensor.

It's implemented with interrupts and no one wakelocks at all, that means:

No lags. It will always work and will be as responsive as if you pressed power button instead.
(If it still got lag than you would got the same lag if pressed power button at that moment instead.)

Power consumption as minimal as possible. It doesn't keeps device awaken like apps from market, so it can go in deep sleep and not consume power.
The only power is needed is to power the touch screen and/or proximity. It still consumes power but that is neligible.
See proof screenshot below.

You may say that 1.2% per hour is a lot but take in mind that I have 4 years old battery that doesn't work long any longer.

It has no timeouts. Why need them if power consumption is so low?
I've always hated apps from market that works while you play with them and don't in an hour.
But they at least had reason of big power consumption due keeping device awaken.

How to enable and setup:

Again you need to use third party app like "Trickster MOD" (Requires root) to activate and edit it settings.

The property "Delay" sets mode, not delay (I used settings from old version).

Touch - wake device by touching screen

Proximity - wake device by proximity sensor

LongTouch - addition to Touch. If long press screen than device will sleep again after finger released.
Example: Touch and hold, device will wake up you will see what you want (e.g. time), release, device fall asleep again.

1 = Touch

2 = Proximity

3 = Touch and Proximity

5 = Touch and LongTouch

7 = Touch and LongTouch and Proximity

Manually setting from terminal

enabling

Code:

echo 1 > /sys/devices/virtual/misc/touchwake/enabled

setting mode. multiply desired mod on 1000. e.g. 7 = 7000

Code:

echo 7000 > /sys/devices/virtual/misc/touchwake/delay

Installation instructions

Code:
Code:

*** Disclaimer This kernel only for [URL="https://xdaforums.com/t/3334574/"]Unlegacy-Android[/URL]. Sure you can try your luck in booting it on another ROM, but that is probably wasting of time.

Prepare your current zimage or boot.img backup for case this kernell will not boot

Boot in bootloader manually or by adb command

Code:

adb reboot bootloader

Flash downloaded zimage with fastboot. Replace zimage-file with path to downloaded zimage.

Code:

fastboot flash zimage zimage-file

Reboot

Code:

fastboot reboot

Sorry for not providing flashable in recovery zip. I had some problems with it.

Thanks for your reply @Voron.exe
I build VoronK touch-wake from source but it still not boot on 7.1.1. so I applied your commits on the aosp-7.1 branch of UA tuna kernel and resulting kernel boots fine.
Let's me test how touchwake work (tomorrow).
thanks

Cool! I was going to make the same today but you did it first. )
Going to publish that 7.x version a bit later.

UPDATE:
I've try ua_tuna-ota-20170122 (aosp-7.1) build and it doesn't boot even with stock kernel.
What build is the last working?

fiox · Jan 23, 2017

Ei Voron.exe, thanks for sharing your work.

I just want to point out a wrong link in the first post --> VoronK-zimage-5.x-7.x-220117-f6cad32 (link to 4.4 version).

Only for distracted people like me (I've flashed the 4.4 kernel on 6 build LoL)

Flashed the right version, and all is ok!

thanks!

I don't know, but I remember @Ziyan saying that 7.1 isn't booting yet, and they're still working on it

None of them, you need to rebuild a permissive kernel to be able to boot 7.1.1. ATM all nougat builds for tuna from unlegacy site bootloops due to some selinux denials.
Plus, to successfully build a tuna kernel from 7.1 ua branch you need to revert these two commits, which borked kernel build:
http://gerrit.unlegacy-android.org/1151
http://gerrit.unlegacy-android.org/1153
Hope it helps.

Oh..
I've spent a day and finally got working version for aosp_7.1_tuna_2016-10-21.zip that I published.
For 7.1.1. no luck. You said that have successfully booted by own build?
I can add your version here if you don't mind, cause I get tired of these rebuilds and don't want to spent more time on version that I am not going to use.

No problem, PM me a way to sent it... I've fresh built touch-wake-7.1 branch, works on today UA build.

Just a bug report: during a phone call proximity sensor is active and if you have enabled "power button end call" in Accessibility menu it hangs call. Thus even if you have enabled only touch or touch and long touch....

It's working flawlessly in ua_tuna-ota-20170116 (aosp-6.0) build, but I haven't tried phone calls. Could you consider to implement, if it's not to difficult, double tap to wake instead of only one tap?

massoudsh · Jan 24, 2017

oh my god...new kernel for old Gnex, it is excellent!!!:highfive:

I've already done workaround for phone calls and some more fixes but not yet published.
As for double tab I will see what can I do. Wait a bit for new versions soon, current is a bit buggy.

UPDATE THOUGHTS:
I am currently thinking on implementing all this in kernel module instead of rebuilding kernel.
The PGM/TouchControl guy did the same, sadly he didn't open sources and abandoned development for few income.
If I'll succeed than probably I'll turn this project into an app.

Voron.exe · Feb 1, 2017

Okay. I've done some work and have some success with modules.
I am planing to make and app that will allow to add this features (touch wake and color control at least) to any tuna kernel and rom and possible in future to other devices too.
The app will (obviously)require root and will be shared for free without ads/trial/limitations but with optional donate.
Does anybody interested in such app? Is it worth to continue?
Cause I've reached all features I wanted and there will be no sense to continue develop if no one interested in results.
Please tell me what you think!

I think that's a great idea. I think you could probably do it far more easily with AnyKernel2 also.

Seems a very interesting project to me as i'm currently running VoronK on top of ua.
Thanks

As I understand AnyKernel2 is a script for flashing a kernel into ROM with any ramdisk (Am I wrong?).
If so I can't see any benefits of using it, cause there are much bigger ROM/Kernel incompatibility issues than just a ram disk.
What I do (and almost done) done now is a kernel modules that can be loaded in any kernel (almost) so I can no more care about building own kernel for each ROM version.
Instead I will care about compatibility with different kernels. On the other side users will be free to use kernels which they like.

Thank you too! Your posts make's me to continue developing, although it's not easy, cause I have to study also.

I wonder how many Galaxy Nexus devices still in use?
I fill like there about 100 in the world and I am one of them!
Hope that isn't true =D

osm0sis · Feb 1, 2017

You can use AnyKernel2 to flash over any ramdisk as well as any zImage if you want, check out my GN Synapse Injector zip. So if you want to add modules, etc. to any kernel/ROM AK2 should be much easier than an app I would think!

bamtan2 · Feb 1, 2017

I cannot comment on technical issues, but I do think color control is mandatory in a ROM. And in any computer system, in fact.

One big release of CM13 has 9000 downloads, and a big release of UA 7.1 has 10,000 downloads. Maybe half or less of all current users would ever download these. Personally I have not downloaded either. So I think your feeling is not true. There are more than 100 Galaxy Nexus users.

With the app it's not hard too. It's like "insmod mymodule.ko". Only needs a root.
App can download anybody and no need to deal with recovery and manual flashing.
Anyway app will needed to control module settings. I think it's more user friendly..
