tried several kernels and come back to Matr1x again <3
[Nexus 4 Original Android Development] stuffynet:
I give up. Flashed rastakat with matrix (clean) still dellay. Flashed without kernel no dellay. O well. Back to purity stock.
[Nexus 4 Original Android Development] Blackcrx:
Same. But I always go back to 12.5
[Nexus 4 Original Android Development] SweetPant:
what's wrong with 13.0 ?
[Nexus 4 Original Android Development] ensboarder:
Nothing
[Nexus 4 Original Android Development] SweetPant:
I am currently using Rastr1x but don't have delay problem...
[Nexus 4 Original Android Development] Blackcrx:
Personally I find 12.5 to be smoother than 13. But that's just me.
[Nexus 4 Original Android Development] jimyiak:
Great job here!!!with latest purity that's always my rom,great combo!!

But it wouldn't be even better if we have the fixes from linux kernel 3.4.82+???

[Nexus 4 Original Android Development] Chochiwpg:
Mathkid, you planning on releasing this kernel on the Nexus 5. Matrix was one of my favs on the Nexus 4, kind of miss it on the Nexus 5. Peace.
[Nexus 4 Original Android Development] Maibol:
hey mathkid can you add francos interactive gpu governor ?
[Nexus 4 Original Android Development] TheNerd:]:
I think he has.... Anyways long time no see didn't know you got the Nexus 5
[Nexus 4 Original Android Development] Chochiwpg:
Ya, got it about a month after the release and sold my Nexus 4. I'm around the Nexus 5 forums on a daily basis, just felt like checking in and seeing how the old stomping grounds are doing :good:

Peace

hello

on pa beta6 i flash v13.0

or

CFS – GPU OC

thanks
[Nexus 4 Original Android Development] dppow:
If you don't want to over clock yr GPU flash the first one otherwise flash the GPU OC version
[Nexus 4 Original Android Development] Toyotaspeed:
I am using Paranoid Android 3.99 RC2 (Android 4.3). Which kernel version should I be using?
[Nexus 4 Original Android Development] philneo2:
thank you :o
[Nexus 4 Original Android Development] Ulqiorra:
Guys can you please tell the most battery frienfly settings for Matrix v13? Thx in advance
[Nexus 4 Original Android Development] Bonjo12:
You need to use version 11.0, and you also need to flash jss to jwr screen tearing patch
[Nexus 4 Original Android Development] playya:
thanks for coming back to some of us old tymers... LOL... If this is not on the N5 I am glad I did not get one yet since this kernel is leaps and bounds above the others in reference to battery life without taking away from performance. I am running Ondemand now and my battery life is as good as interactive or wheatley... :good:

---------- Post added at 10:04 AM ---------- Previous post was at 10:02 AM ----------

subjective - play with all settings do some googling and test on your device. Try all governors and cpu speeds. Your answer is not just a,b,c it's a-z
[Nexus 4 Original Android Development] HiM@L:
i do know you guys from Hercules days..anyways, r u on 12.5 or 13 ?
[Nexus 4 Original Android Development] playya:
think 13 today been running both for testing purposes..
[Nexus 4 Original Android Development] Chochiwpg:
Ya, it's not on the Nexus 5 yet. My go to kernel on the Nexus 5 is ElementalX. Another great kernel for balance of battery and performance. But still miss Matrix. Nice to hear from you Playya, have a good one.
[Nexus 4 Original Android Development] xenyz:
Well I have entered the Matr1x again after testing a bunch of other kernels. Although some others gave a small improvement in battery life, nothing else is as stable for me as Matr1x is.

My wish list to make this kernel even better. This is more for the benefit of others who use 'stock' Matr1x:

There's no init.d in ramdisk. I have to use Hells-core installer before Matr1x installer to get the init.d script support. You could borrow the edit ramdisk script from Hells'.

The default -100 mV undervolt is too much for my Nexus 4, but a -75 mV undervolt is just fine. Raise the default voltages a tiny bit to be safe.

row io scheduler beats deadline, this should probably become the default.

The bundi22 gamma profile is still not exactly the real profile, it's close though. :)
[Nexus 4 Original Android Development] playya:
Not too shabby for me with Ondemand...

---------- Post added at 06:23 PM ---------- Previous post was at 05:36 PM ----------

nice wish list and I hear ya but have you ever thought of developing yourself? Most of your changes are subjective and can easily be done with the use of an app. Maybe Matr1x makes his kernel to suit him and simply shares it with us. Either way if you get into developing and make a kernel for yourself share it with us and hopefully others wont tell you what to fix..... LOL :laugh:
[Nexus 4 Original Android Development] xenyz:
Perhaps I'll give it a shot, but for me so far, this is working out just fine. I do make the changes I posted, they were more for others to enjoy without having to do anything but flash. Of course the dev can do what he wishes, it was merely a suggestion, and not intended to sound like I was telling him what to do. :)
[Nexus 4 Original Android Development] philneo2:
what do you recommend governor with Matr1x v13.0 * for battery life ?

thanks:)
[Nexus 4 Original Android Development] xenyz:
ondemand or wheatley, depending on your usage. Try both.
[Nexus 4 Original Android Development] philneo2:
Thanks i try weathley . i using ondemand and it's very fast :)
[Nexus 4 Original Android Development] RealSlimShadyMC:
Ondemand drains battery heavily while multitasking

Guys..Can anyone help me tuning the interactive Gov in v.13..

Don't know why but it does not feel as smooth as in V12.5...At first i thought that my gov settings got messed up due to dirty flashing.But problem is something else..Today i did clean Flash & there is severe lag in Beach Buggy Blitz..Ui also does not feel smooth...

Just now flashed 12.5 & everything is buttery smooth again...Now that i noticed,v13 has got some extra parameters in Interactive Gov..I'll be experimenting with the values until i get same experience as older versions of Matrix..i'll appreciate if someone helps me out here

It's just not you..I also feel the same thing..
[Nexus 4 Original Android Development] playya:
Why do you have to use 13 if 12.5 runs better for you. Don't stress yourself man run 12.5 and enjoy
[Nexus 4 Original Android Development] philneo2:
thank you for the advice I am currently trying wheatley;)
[Nexus 4 Original Android Development] snak3ater:
Yeah..12.5 looks good but still wanted to tune v13 to get best experience.. playing with other parameters.. Let's see

Oh ok no problem good luck... I am running V13 with On demand and stock settings and if you scroll a page back you can see my results...

Thank you for your work.what is the difference between 12,5 and 13? I feel the 12,5 more smooth but what changed?
[Nexus 4 Original Android Development] Alvarinho20:
Does anyone else has problems with exchange? When I install for example telegram I geht the FC Massage of exchange. And I think this is why telegram doesn't read my contacts...?
[Nexus 4 Original Android Development] xenyz:
By FC do you mean the app has stopped working message? Try raising voltage by 25 mV using Trickster MOD. I get random app closing unless I do this.
[Nexus 4 Original Android Development] Alvarinho20:
No only when I install the app I get "exchange Dienste wurden gestoppt". Then telegram does never find my contacts. Sorry for my bad english
[Nexus 4 Original Android Development] xenyz:
I'm not sure if it's the same message I get or not. Can you take a screen shot?

Either way, if it's the system error it could be the voltages too low, otherwise its a user space issue and not related to Matr1x kernel.
[Nexus 4 Original Android Development] xenyz:
I don't see the 'report' button next to OK, so I'm guessing it's an app problem and not kernel related.
[Nexus 4 Original Android Development] nexuspur:
[MENTION=2677519]mathkid95[/MENTION] nice kernel. im running v12.5 for now because it gives me more performance and better bettery life than v13. my device keeps always cool, good bettery life and super performance with interactive governor. i think the minimum frequency is always good at 192mhz. so all in all super kernel good job:good:
[Nexus 4 Original Android Development] dermarks:
I really like this kernel, but I am having the problem that sometimes my touchscreen freezes after waking up the device. Only a reboot sloves it for some time. Sweep2wake and DT2W are both disabled.

With other kernels I tested, this didn't happen, but performance and SOT is much better with Matrix. Would be so great without the freezes :cowboy:
[Nexus 4 Original Android Development] playya:
please search thread since your not the first to have this issue and if you do not see an answer please pm another member that had your issue and see if they resolved it. dt2w and s2w were normally the problem so make sure you do not have script activating it or another kernel tuner running... Good Luck
[Nexus 4 Original Android Development] exen1986:
Hi, I am using Matr1x Kernel 13.0, it is so smooth and fast but the problem is my battery life, here i see some users that have 4-5 hours of SOT, i have always 3 hours SOT. I don't have any information about trickster mod and UV settings, i just read here ondemand drains battery too much so i changed it wheatly, what about other settings about battery life? Thanks.
[Nexus 4 Original Android Development] arffrhn:
Battery life depends on your apps and usage really. What apps did you install? How much of them ia running in background? Did you always use 3g? You can save more by using wifi instead of 3g. There are many tips on saving battery. Try those out. To me if you are always on 3g, then 3-4 hours is normal.
[Nexus 4 Original Android Development] dermarks:
Thanks for your reply. I searched before I posted. That's why I mentioned that dt2w and s2w were disabled. The freezes appear anyway. I'm on Stock with GravityBox and TricksterMod, where both settings are disabled. No other scripts or kernel tuner in use.

If someone else is facing the same problem, would be great to let me know, especially if you have any ideas how to solve it. Thx :)
[Nexus 4 Original Android Development] dmourao:
Yea... If he is all the time on 3G, 3h~4h is a pretty good time.

[Nexus 4 Original Android Development] exen1986:
The problem is i can't use 3g. i am always using 2g or wifi. With 2g i have 3 hours sot. i have just basic apps;Facebook twitter, an email sync one hour, whatsapp that is all. With 3g i have just two hours sot.
[Nexus 4 Original Android Development] hooligan_016:
I'm starting to have this problem as well, not sure what is triggering it. At first I thought it may have been PocketCasts, but I had a freeze earlier today just randomly checking it without any background activities occurring. No other excessive tweaks, all stock on GEL (interactive, row, cubic, simple gpu). I switched the gpu governor to ondemand, so I'll see if that makes any difference.
[Nexus 4 Original Android Development] Mohannad-K:
This issue from 12.5 ...I'm first guy report this issue to u and still somebody not believe and think its from script or other things
[Nexus 4 Original Android Development] ilyadan:
I can see the vast increase of this freezes when I install xposed framework. After uninstalling the xposed from my ROM the freezes almost disappeared.

[Nexus 4 Original Android Development] Mohannad-K:
I don't have closed installer

This issue happened randomly and some times
[Nexus 4 Original Android Development] xenyz:
I ran Matr1x 12.5 for a month or so in Jan-Feb and noticed it too. Didn't happen very often, but once in a while the digitizer stopped responding. I forget if it happened with the stock kernel as well...
[Nexus 4 Original Android Development] dermarks:
I was on Stock for several months before I changed to Matrix and I'm sure it didn't happen there.
[Nexus 4 Original Android Development] chappy824:
I have been running Matr1x forever and have zero stability issues. I'm sure this is ROM related or phones that can't handle the UV. Try bumping the voltages up a bit or get a logcat next time you have issues.
[Nexus 4 Original Android Development] dermarks:
Maybe you are right and it has something to do with UV. I have "fast" CPU, changed the voltages now and will test if it happens again.
[Nexus 4 Original Android Development] dEris:
v13 has OTG support right?
[Nexus 4 Original Android Development] tommypacker:
Yes
[Nexus 4 Original Android Development] dEris:

AFAIK, all apps to control gamma are paid apps. Support your local dev and buy faux clock or trickster, or instead use the free option: init.d scripts.

Is there any chance of you porting it in the near future????

Can't beat Trickster Mod /donate. Worth paying the extras you get. Depending on the kernel it does more. On Mat1x it's the best, IMO

[Nexus 4 Original Android Development] scissorscrush:
Never mind not gonna use matr1x anymore, apparently it can't handle nfs and rebooted twice while playing that. Going back to hellscore.
[Nexus 4 Original Android Development] xenyz:
It's got to be low voltage -- Matr1x is the most stable custom kernel. I have to +25 mV though; the default undervolt is a problem.
[Nexus 4 Original Android Development] arffrhn:
Mate, just use whichever kernel you want. You don't need to write it like that because without you noticing, some peoples may be hurt by your words. It can be translated as a disrespect behaviour towards the dev too.

Just a piece of advice in the future. We're a community here after all. :)
[Nexus 4 Original Android Development] howard bamber:
I agree but I've gone to the nexus 5 and really miss matr1x. It's the best there is and the sooner Mathkid can port it the better. My phone is not the same without his magic.

You use another kernel. Your loss. Did you give it time to settle?

Sent by mobile telephone.
[Nexus 4 Original Android Development] badaas:
Have gone to default volts +100 since reading the gains of UV are minimal, ie. +2% battery gain vs loss of battery due to reboots. ?

sent from a phone etc.
[Nexus 4 Original Android Development] Broooooook:
The reason for undervolting is to avoid overheating, not to save battery. And properly-set UV (which depends on individual device) won't lead to reboots.
[Nexus 4 Original Android Development] kassu99:
Sorry for noob question :)

Will matr1x kernel work on cyanogenmod 11?
[Nexus 4 Original Android Development] 26.2man:
So you are saying undervolting saves no battery. So what does then?
[Nexus 4 Original Android Development] Broooooook:
I would put it in this way: I did not notice a big difference w.r.t battery life with undervolting. IMHO, battery life depends more on the cpu frequency, cpu governor and most importantly, your apps and settings.
[Nexus 4 Original Android Development] snak3ater:
It's used to keep device cooler.. We got governors & hotplug driver to take care of battery/performance..UV plays very little part in saving battery
[Nexus 4 Original Android Development] Broooooook:
Only AOSP-based ROM for now. But if you look one page back, you'll find that mathkid is working on the cm version.
[Nexus 4 Original Android Development] scissorscrush:
I totally understand that but it is my duty to share my experience with the community. I flashed matr1x first time and i got great battery life, it was like 87% left with 2hr of SOT but full of lags. Then second time I flashed it, I got performance better but the battery life was not good but got the reboot without any reason. I checked it after +100 but same. I gave it enough time to test.

Not getting disgraceful to anyone, it might have worked for someone else.
[Nexus 4 Original Android Development] badaas:
Yh, sorry, it works for cooling. I dont play games etc., I have only had one SOD/power off with matr1x @-100 [MENTION=3296700]192[/MENTION]/118800mhz ondemand gpu/wheatly cpu... That was after i froze email/exchange on Purity rom, so i even now im thinking rom had a brainfart... But Matr1x is still win for me, all good.. as 99.9% of this thread suggest :_)
[Nexus 4 Original Android Development] xenyz:
I'm testing a low frequency interactive vs wheatley governor at the moment. I'll post settings and results when I have them, but initial testing gives me even more battery life than wheatley. Stay tuned.
[Nexus 4 Original Android Development] Swords.Grizzlebee:
Try to be more tactful. You don't need to write which kernel you will be using instead of Matr1x. Also if you get a reboot that isn't related to undervolting you should at least offer to try and recreate and post logs for the error, otherwise don't post about it.
[Nexus 4 Original Android Development] playya:
haha I as well have moved on to a different phone and honestly will miss this kernel but I must say the subjective posts are exactly that subjective. If this kernel does not work for you you simply move on and its not your duty to let everyone know that you do not like it or you are moving on to another kernel. We will all be fine with that decision.

Just an fyi for anyone else that likes to share their experiences. Like said prior there are tactful ways of doing this and if you cross that line remember you are disrespecting a developer that does this for free. He/she may not take your words the same way you think they should so be careful when typing or just simply STFU...

Matr1x works its been proven and if it does not mesh with your rom then choose one of the other half dozen kernels but its ok if you dont tell us
[Nexus 4 Original Android Development] xenyz:
After a week or so testing on various kernels, here's the Matr1x version of the low frequency interactive governor. You need root to change these settings; by now I'd imagine everyone knows how to do that. Although not quite as good as intelliactive, this still gave me about 5-10% more screen on time vs wheatley. I have a feeling it's because the energy consumption goes way up after 1026 MHz and this seems to keep it at and under that for ~75% of the time, with ~66% in the lowest frequency step. Try it out and report back how it works for you.

This m4tr1x kernel is only for aosp based rom so its not working with cm based rom...

But u can find in back page mathkid is working for cm based kernel...

[Nexus 4 Original Android Development] mclisme:
A stupid question maybe, but after I try different color profiles (Google, LG, Pa Brighter etc.) how do I revert back to Matr1x's "stock" profile (iphone5)? Is there such an option which I don't see or I have to re-flash the kernel?
[Nexus 4 Original Android Development] xenyz:
Are you using faux clock, trickster mod, kcontrol, etc? If so, you can save gamma profiles.

You don't reflash, just reboot to get defaults back.
