[Q] matr1x kernel + stock 4.3 Android = graphical/animation stuttering? - Nexus 4 Q&A, Help & Troubleshooting

Hi all,
I am hunting for a Kernel that can give me improved battery life on the Nexus 4.
At the moment I am using stock 4.3 Android (I did try CM and AOKP in the past).
Today I installed the matr1x kernel v11 as I heard good things about battery life.
All seems to be working fine except for the following:
When I am swiping screens, I notice some graphical stuttering, as if certain areas of the screen are not running the animations as fast as others, i.e. screen tearing
Anyone else experience this? What could be the cause?

Please ignore/delete.
Did some more reading, and found a patch for matr1x kernel and screen tearing on JWR based ROMs.

ics rom issues

so ive been runnning ics roms for awhile now (since one of the first functioning cm9 builds were out), and im not new to flashing. but im a little unsure what i should be running that will fit my needs the best. im running slimics 3.7 right now with its stock kernel, and its great, if you get rid of their 'stock launcher' and change the screen settings, i just feel like i could be getting more. ive heard wonderful things about dark knights rom, but havent had a good experience and i dont know if its due to me flashing improperly. i started out on icssgs and it did me well....i just find slim a but of a step above (my opinion of course). but i find slim releases their updates before many apps become available to it. im just a regular user, i use facebook and web alot, and of course text, and camera, i also desire as much battery life as possible (of course) while running the best performance with what i need. Are there any suggestions for me out there for a rom/kernel combination?
Hi,
Did you already try MNICS kernel with SlimICS ?
I've got the best user experience with this combo.

+1.....mnics is a great basic kernel designed for everyday use, with a specially tweaked conservative governor for smooth ui experience, and good battery too

What's you're favorite kernel?

I just got a nexus 7 2 days ago and I'm going to root it this evening when I get home from work.
I want to have you guys opinion on which is the best/favorite kernel amongst you guys.
Personally Id like a kernel that's as smooth/fast as possible with decent OC capabilities. Battery lifes not an issue to me as I don't mind charging my tab everynight.

Hi, I use Clemsyn's Elite Kernel, it fast and offers great battery life, you can also OC to about 1.7ghz but I stay at 1.4 as I find that fine
Just wondering if anyone else has tried glados kernel, it was running nice with great battery/performance but started causing reboots so I'm back to trinity. Will be keeping my eyes on glados though!

I use the 520 mhz GPU version of Motley 1.1.1. I find it very fast and mostly smooth. There are a few problems with UI lag I have seen that seems to be related to this kernel but I can live with that because of the IO and general performance benefits. (Plus it will probably be fixed in an upcoming update anyway!)

Hey mate Nice phone you have there
I like Faux's kernels, I have always admired his work, the N7 is the first device with his kernel and I am using it right now
The newest kernel, from a few hours ago is slightly underclocked, performance is still top notch in day to day use, it has the tegra gaming fix, so many features and battery on previous version was great. I am looking forward to seeing what battery on this new one is like
I found Glados kernel to have issues randomly freezing where I had to press all 3 buttons to reboot it, and Morfic's kernel lagged a bit on the apex laucnher homescreen I have
No offence to those kernels/developers, but faux's kernel is my favourite now
But it is still early days in the life of this device
I tested all these with AOKP nighty builds

Very nice phone
I will probably try Faux's kernel out sometime but i'm really holding out until an update rolls out for motley.
OFFTOPIC - Have you tried the nik's JB builds for IncS? And if so, how have they been? (thinking of flashing CNA but not sure if I should wait for the new kernel to function with AOSP.)

Try faux's kernel, as I said its my favourite
Yeah I have, but they are not as butter smooth as they are on the N7 or even the Nexus S. I think it has to do with the hacked kernel and drivers. I am waiting for a proper kernel that can properly handle project butter.

[Q] Scroll stuttering and kernel question.

Hello world! My brother recently bought a Nexus 7. He unlocked it and did all sort of nasty things to it.
First of all, he installed latest CyanogenMod 10.1 nightly and changed the kernel to latest M-kernel.
When he slowly scrolls, there is stuttering (sometimes if you focus) and it's annoying. Is there any way to fix it?
Now for the kernel question. I want to show him a kernel like Siyah on Galaxy S 2 9100(I'm an S 2 owner) because this particular one provides stability and performance. Is there such kernel for the Nexus 7? (If you know about Siyah)
Thanks in advance guys!
P.S: The Google search I did was saying something about Google Currents, but it's not installed here.
BUMP! Come on guys, you can do better than that!
Both Franco kernel and Faux kernel are great. Franco's does not support overclocking, Faux does. The one I use is clocked at 1.4 - not too high, but it does make a difference. Smooth and stable.
Well, which one do you use? Care to mention?

M-Kernel mr1 easily seems like the best choice to me. Greatly improved performance with just slightly worse battery life (because of OC).
Any stability issues you encounter are likely a cause of the ROM you're using. Especially if you're using a nightly build.
The "stuttering" is either because of the hardware in the Nexus 7 or because of Android itself. I'm pretty sure you won't find a ROM or Kernel that removes that.
It's because there's a minimum scroll distance, that makes it look stuttery when you move your finger very small distances.
Scrolling with what app? Some always stutter.

[Q] CM 10.1 vs stock: battery life, performance, etc..

Running stock rooted. For all my other phones I've ended up on CM, and I think the N4 will end up the same.
How's battery life with the CM10.1 Nightly kernel? (Would probably flash to Franco anyways, but just curious).
Performance (smoothness, etc)?
Little additions you love on CM not in stock (Quick toggle the widgets, etc)?
Let me know anything else!

I've been an avid user of faux123's kernel. I mostly used the enhanced stock. The kernel is smooth as heck, but from day to day use I do not see a whole lot of difference between that and cm10.1 nightly kernel as far as battery life is concerned. The reason I recently quit using faux123 enhanced stock was because it recently starting making my hands free calling in my explorer do some weird stuff. Once I reflashed the rom (simply to just put the cm10.1 kernel back on) the problems went away.

[Q] Optimal Setup for Nexus 4?

Hi!
I got my Nexus 4 three days ago.
My Usage Specs -
I use my N4 mainly for internet ( WiFi, sometimes 2G ) and a little bit of gaming. I make occasional calls and text rarely.
I don't use WhatsApp or Facebook.
I'm using STOCK ROM+Kernel.
I'm getting around 10-12 hours of battery life, with 4-5 hours of screen-on time.
Now, I want to be able to over/under clock & volt my CPU+GPU. This is to increase battery life and increase performance, as required.
It looks like too much choice is very confusing. So, I'd like some experienced suggestions and recommendations.
So, which _ should I use? ( And, I've already narrowed down the choices a bit )
Kernel - Faux, Motley, Franco
ROM - AOSP(Stock), CyanogenMod, Paranoid Android, Xylon
Also, should I use Battery, CPU, RAM managers? If so, which ones?
What are some cool, useful N4 specific apps?
Any other tweaks and tips? - You can link to other xda threads, if available.
I will be unlocking and rooting tomorrow, once I decide which kernel+ROM to use.
Thanks!
Ram and battery managers are not necessary. You have 2GB of ram. Battery saver apps do not work. besides you said you're getting 4-5 hours of screen time. That's great!
Download greenify. It's a great app.

OP, "best ROM/kernel" questions are not allowed here. You will have to experiment and see.

Hi,
I understand that you are trying to prevent flame-wars and the like, however, I'm not looking for 'the best kernel/ROM'.
I want to know which combinations and configs other people have used, and I'd like some experienced suggestions.
I'm finding it confusing to differentiate between the variety of kernels and roms available, so I wanted some recommendations - preferably, with reasons.
Thanks!

I use Paranoid Android with its stock kernel. For me, no other rom can compare to Pa on the nexus 4! Not even cyanogen mod is as fluid, stable, and efficient. With my current setup I get around 16 hours battery life (5:30 am-11ish pm), with ~5 hours screen on time. I don't use any task killers or memory managers. I just make sure to force close all my apps when I'm done with them, and I reboot the phone every 24 hours to keep it at its maximum performance. Although my usage is slightly different. I use my phone mainly to browse the Web, text and occasionally snap some pictures and check instagram. Hopefully this helps you out a bit

Thanks! This is exactly the sort of information I was hoping for.
I think I'll try out PA today.
Also, Have you tried other kernels?

Trinity and Franco kernel works great with PA. And so does semaphore. I use Franco kernel mainly because I get more screen time than any other kernel I've used. Franco kernel delivers a balance between smoothness and great battery life.

Okay, and you use PA too?
Also, how does the kernel affect smoothness? Shouldn't the performance be the same as long as you don't change clock speeds? Or is it due to the new governors that the kernel uses?
Also, what about motley kernel? The thread is very spartan, and I can't glean much info about it.
Has anyone tried Xylon? - it looks efficient.

I've tried the Franco kernel before but I find the stock PA one to be perfect as far as colors go. I've never had an issue with smoothness using it and I don't even worry about clock speed or governors. As far as xylon goes, I found it to be very washed out using the stock kernel that comes with the rom, again in terms of display. When I ran xylon for a few days, I ran into a few hiccups in performance that weren't acknowledged, even when running with different kernels. I've also tried AOKP, Cyanogen, and axiom, but I always return back to paranoid

Okay, thanks. I'll experiment a bit, and see how it goes.
I've used PA before, on a HTC One V. It looks great, IMO too,

HI!
So I have experimented and tested most of the major kernels and ROMs.
AND..... My selection/combo for now is:
kernel - Franco Milestone 2
ROM - Carbon 1.7
I tried Paranoid Android, but I didn't really like their interface adjustments.
And, just CyanogenMod is boring, IMO. Xylon, too.
Carbon has great customisation, and the specific adjustments that I like.
Thanks for the help!
Others - feel free to continue post your suggestions and recommendations for kernel+ROM combos.

Oh, I wasn't really sure whether it was stable, so I went with the milestone release.
Also, What are prime drivers?

Drivers with code from Code Aurora. They *may* fix stuff like slow WiFi speeds and delayed notifications. I personally use them but if you don't experience any problem with WiFi then I suggest flashing the normal ones. :fingers-crossed:
Try Matr1x kernel, gave me the best results when I tried through different ones.

I think I'll use the normal ones.
My internet speed is 4 Mbps and I don't use my WiFi to transfer files at all.
At the moment I'm getting the speeds I can technically get. So those won't help me, I guess.
Also, I've been running R140 without any problems for the last day.
Thanks!

They're pretty much the same really. But Matr1x does wonders in benchmarks. I would love to use it however I need those Prima Drivers badly :S
