Whenever the GPU goes into idle mode it is displayed as 320 MHz. Nothing wrong this is also stock kernel behavior.
[Nexus 4 Original Android Development] playya:
double tap to wake is there and you can see it in the changelog

Also instead of using an app try running the script and see if you have the same freezing issues.

[MENTION=2677519]mathkid95[/MENTION] amazing kernel. Using with liquid smooth 3.1 6/20 build with synapse/ukm and have one question, any way you can add 384 as the max screen off frequency?

[Nexus 4 Original Android Development] ruzkay:
I am still using the CFX ROM which unfortunately got discontinued. Well I'm sure there are other fast ROMs. Just pick a fast ROM set window animation in developer options to 0.5. Also I use Nova Launcher don't know if that makes any impact but it feels solid compared to others.

I let Matr1x kernel completely on stock because I believe the developer made the stock settings so that it works well (and he certainly knows more than me).

But you must consider that our device still is "only" HD while the current flagships are FullHD and are heavily customized and skinned and whatever so yeah while you might have more FPS in games and stuff with new phones (I am talking about stock) but a N4 with a custom ROM and kernel will breeze right through the OS.

What makes this phone feel really fast (at least with my configuration): I have the home button as a double for app drawer and when I click it as fast as I can it will instantly open and close the app drawer. It happens without lag and you can't say that about all current phones. Most iPhone owners with their snail animations were impressed (btw I actually like iPhone just we all have to admit animations arent the fastest).

TL;DR: The stock software on current flagships is really poor on the speed department especially Samsung with their S-Lag feature on their newest revision of TouchWiz.

PS (For all who don't know how to enable doubletap to wake): I use Semaphore Manager, since the changelog says it uses stratosk's doubletap mod I figured his official app would work and it is also free and it did. The feature is under "Tweaks".

Any reason for S2W being removed from the latest version? Surely whoever didn't like it/use it could have let it OFF, whereas for us who used it it is now a great inconveniece :(
[Nexus 4 Original Android Development] playya:
that can be easily fixed my friend all you have to do is simply go to the OP and build your own kernel based off of mathkid. Add in s2w and all done... Seems simple enough [emoji3]

Hey guys, first time here.

I'm on Mahdi with AK kernel since a couple of months. Everything is super smooth, but... in the kernel thread they said Matr1x is good for battery and AK for battery and performance, so now I am undecided!

Does anyone knows what maybe I can gain by switching to Matr1x? Is the msm_hsic wakelock reducer working good?

Also, does this kernel have GPU voltage control?

Thanks a lot!
[Nexus 4 Original Android Development] THEBANDIT420:
This better than ak for battery even with the same settings in my experience and no GPU voltages here but seriously UV the GPU does barely nothing anyway
[Nexus 4 Original Android Development] iRefleX202:

[Nexus 4 Original Android Development] xX NeOnShK Xx:
Whoa dude! Thanks a ton! Can you tell me how you found the files? They are at different locations for different kernels?
[Nexus 4 Original Android Development] mclisme:
Ok but using that reasoning I guess many other features could be dropped as well as they would be super easy to be added back in right?

I use this kernel since a long time and it was more a question of curiosity how come such a handy feature was suddenly left out. For example, there could be compatibility issues between S2W and 4.4.4 or maybe Mathkid discovered a bug of it etc.
[Nexus 4 Original Android Development] shilera:
Worse than 4.4.2
[Nexus 4 Original Android Development] T-luvR:
Thanks dev. For hard work but its not as fast and smooth and battery friendly as it was FOR me! I have lag in some games like minion rush (that I had lag before as well) ,angry birds star wars and a little fly in waking phone some times I think lags are because switching cores ! Cause while minimum core is on 4 the lag is almost gone! And I repeat maybe it only for me ! I donno my phone is bad or the ROM I use or maybe I have flashed or installed bad thing( that I think I haven't) thanks a ton for hard work for our old nexus
[Nexus 4 Original Android Development] Italico:
First time on Matr1x, using Mahdi latest build. So far so... super good! Even at 1.5GHz it's smooth as AK at 1.7!

Less tuneables (I'm using Synapse) but the ones that I like are there and useful. Wheatley governor too seems a good one, paired with FIOPS scheduler. Now let it settle and compare battery usage.

Thanks to the dev!
[Nexus 4 Original Android Development] playya:
I understand what you are saying but you keep making it sound like this is so easy and for that I am saying then just do it yourself and it will solve all of your issues. Mathkid may of had issues with s2w or not but on his kernel he can do what he likes. just lime you will be able to on yours...

I will do you a favor and ask him for you
[Nexus 4 Original Android Development] playya:
not sure if you have but give interactive a try and the row scheduler...
[Nexus 4 Original Android Development] ak:
I think you can't compare because have different governors and tunables. :good:
[Nexus 4 Original Android Development] Italico:
Oh, yes, you're right!

But I really like the governor and scheduler combo, seems a bit slower than ondemand, as I used on AK kernel since yesterday, only when using multiple heavy apps, or installing a lot of them. But for the rest, it is indeed smooth.
[Nexus 4 Original Android Development] ak:
It 'sure, this is a fantastic kernel, but I love to see comments with related technical tests, otherwise we avoid talking about other kernels outside of the correct thread.
[Nexus 4 Original Android Development] playya:
I agree talking about kernels especially negatively outside and even inside their thread should not be done. Technical test are a great way to measure roms and kernels but some just judge simply the old fashion way from there general daily use. All of the kernels in here serve a purpose and help out users in one way or the other.

Thank you for your kernel which I have tried out before but not to get crazy in here lets just let follow the wishes of I am sure both of you and no talking about other kernels....

:good: - Keep the Peace! LOL
[Nexus 4 Original Android Development] mclisme:
I didn't say or imply building a kernel is easy and I certainly didn't make a silly request of the type: "PLZ ADD!!!!!" I would understand the "do-it-yourself" reply if that was the case but it was an honest question, I think you totally misinterpreted my point.

Still, the question remains, how come S2W was dropped? Given that it's been included in previous versions for quite some time and working fine, there must be a logical reply other than "the developer did so don't question him". No offense meant at all.
[Nexus 4 Original Android Development] playya:
:D

No offense and I understand fully what you are saying but the "it must be easy part to add and remove" part is what I was referring too. Its ok I understand you may want an answer on your question but it may be as simple as searching the thread or going back a few days and reading this

I hope thats logical enough for you! :p
[Nexus 4 Original Android Development] snak3ater:
s2w had many issues...It was was like a hit or miss...freezing way too much..And dt2w in earlier versions..Way too sensitive..Phone waking up very easily while inside pocket...Coming towards current dt2w which is the Stratosk's implementation..It's nearly perfect..I haven't had any freezes so far..And it is really precise.Works only if tapped at the center of screen..And there is no sliding menu bug while using stratosk's dt2w..

There are other issues of s2w but i am just too lazy to write all of them...
[Nexus 4 Original Android Development] Axel85:
Is it possible to enable stratosk's dt2w in trickster mod? I can only see touch wake function
[Nexus 4 Original Android Development] playya:
sorry but you can't but please skim through the last few pages to see how to enable it from init.d.... This has been discussed previously.

Thank you, amazing kernel

Thanks for the matr1x kernel. Best battery life out of faux and franco. I use the faux clock app and i tried trickster. How come there are some features missing in one app and the other. Faux is missing battery extender while trickster is missing the c0 c1 c2 states. Is there a full packed kernel app that i am unaware of? Thanks!
[Nexus 4 Original Android Development] mclisme:

[Nexus 4 Original Android Development] playya:
Have you looked in themes and apps for kernel apps because there are a few out there packed with options. Also check out general section for a universal kernel manager

Can you update color gamma? I am using this values 238/228/240 and it looks very good
[Nexus 4 Original Android Development] playya:
When you say *can you" who is the you that you speak of? I am sure his gamma colors are what "he" wants them to be. If your colors suit you may I suggest you set the script up and flash it when necessary. I understand its only a suggestion but you have to remember everyone has a different opinion on what looks good. No disrespect to you at all... :D
[Nexus 4 Original Android Development] Tusnal:
If you use your brain you will realize I was talking to mathkid, I am suggesting this gamma colors because I am sure nobody is using the default settings. No disrespecting you but try to be more useful no a smartass

You don't realize how useful my response was my Friend. Rest assured though I use my brain on a regular and how do you know what people use. I get it its a suggestion....hey maybe he will do it for you...... :D

[Nexus 4 Original Android Development] gregorypeg1000:
Mates,what governor do you use with this kernel?I installed it and saw that,the ondemand is the default one,but the parameters were all the same(optimal freq,sync freq).they were 192000.Is that correct?
[Nexus 4 Original Android Development] playya:
What are you trying to achieve battery life or performance. Try Wheatley governor with simple gpu. Yes 192 is correct its the lower speed which most feel it will help with battery life
[Nexus 4 Original Android Development] gregorypeg1000:
I am trying to achieve something balanced.I don't mean the min frequency.The ondemand governor has some other tunables too, which all have the same setting(192000).Thanks for your recommendation.I'll try wheatley
[Nexus 4 Original Android Development] playya:
For balanced I am sure Wheatley and Interactive will work good for you and I apologize but I rarely ever used ondemand actually. What tunables are you referring too maybe you send me a screenshot or a pm and we can discuss other tweaks
[Nexus 4 Original Android Development] gregorypeg1000:
I meant these 3 settings.When u flash the kernel the stock values are (192000,10,192000)

As for interactive,i use him today since the morning with these settings and 4 cores always online

and the battery life seems great so far

Which app is recommended to adjust the settings for this kernel? Is Tricker Mod ok or should I try another app?

edit:

Another more important question:

Is this kernel still vulnerable to CVE-2014-3153? This was the vulnerability which had to be closed in all major distros, which has been closed in CyanogenMod and which allowed exploits like "Towelroot".
[Nexus 4 Original Android Development] TheNerd:]:
TricksterMod doesn't support the new dt2w, but other than that function it's perfect.

With dt2w that sounds amazing! You're all set buddy. That sounds perfect.
[Nexus 4 Original Android Development] cadarn07:
In addition to trickster mod, semaphore manager from the play store should take care of dt2w.
[Nexus 4 Original Android Development] playya:
Guys to run dt2w just use the script posted in this thread quite a few times its so much easier than having to download an app just to take care of that one function

[Nexus 4 Original Android Development] omgwtfitsp:
Sorry for this noob question guys but what is the difference between the cm vs non cm builds of this kernel? I'm guessing the cm refers to cyanogenmod? Meaning you should flash it if you're running cyanogenmod, yes?

Would it be fine to flash the non-cm build onto a CM rom? I was considering giving liquidsmooth rom a try with this kernel so then should I flash the cm or non-cm build?

Any explanations would be greatly appreciated so I can learn! Thanks in advance

it still comes and goes... are you using simple governor? try ondemand. also try flashing stock kernel then matr1x... but yh,..
[Nexus 4 Original Android Development] arffrhn:
There are two types of kernel for our device now, aosp and cm. Aosp kernel is the kernel based from aosp source by google and it is used for aosp based roms (read rom OP properly, should be stated there). Cm kernel cyanogenmod kernel which includes CAF codes (search for code aurora forum). Caf kernel has different drivers implemented in it so it cannot be used on aosp based rom and vice versa. If you happen to flash a wrong kernel, there will be problems like inverted colours and in the worse case, not booting.

Well that's the short explanation for it. Hope this gives you some idea about cm kernel a.k.a caf kernel and aosp kernel.[emoji4]
