Can the GN ever be as smooth as an iPhone 4S?

Alright, you're gonna be mad about the topic but I'm being honest here.
I never had a nexus phone and I was hoping that if I got a Galaxy Nexus, the phone wouldn't stutter (in browser and in apps) and it does. On websites the stuttering when scrolling is annoying. The phone is fast (home screen, app drawer, settings) but a lot of apps are jittery and not fluid.
I'm running AOKP Milestone 4 with Lean Kernel v2.4.
So my question is, is it possible to get the Galaxy Nexus to be as smooth as an iPhone? Some reasons would be good because there's no doubting the 4s is very fluid with rare if any hiccups.

what apps...all mine are as smooth as the iphone.

AOKP is the king of extra features, but if you want smooth you should try Peter Alfonso's Bugless Beast.

The selling point if the iphone 4s is Suri.
My buddy tried to show it off and it didn't work at all.
He was really embarrassed.. It screwed up everything.
I showed him my nexus, and then I proceeded to pull 15 down 13 up in a speed test.
Boy was he jealous of my Nexus.

If all you care about is smooth scrolling, use the stock firmware. It's smoother than most ROMs, but lacks many features in the custom ROMs.
Don't forget, you're running a beta version of community created code. We don't have as much access to the hardware as the original designers, and can't optimize things as easily.
Whinging about it not being as smooth as an iPhone when you're running user created firmware is like complaining that the shelves you built yourself aren't as nice as the ones that your friend paid a professional carpenter to create.
AOKP runs great for most people, myself included, but there are tradeoffs for the extra features.

also, one more thing you gotta take into consideration is that aokp is more for customization. you want more of a rom that works only on stability. i havnt tried m4, but i do know that bamf is amazingly smooth. and alsooo when was the last time you saw the 4s? sure you can slide smoothly but doesnt it matter much more how quick you can load the page? try a diff browser also... mines working perfectly on google chrome and stock.

That's a poor analogy. The ROM devs are not building these ROMs from scratch, they are making relatively small changes to the code provided by Google. A better analogy would be assembling an office desk from IKEA (store that sells put-it-together-yourself furniture for you non-U.S. folk) vs having a carpenter friend put it together. Sure your friend might drill a hold here or there to make the fit better, but he isn't carving the shelf out of lumber.

stock browser and chrome are jerky but the stock browser is a little better
Stock software was slow for me too, worse than AOKP M4

android will never be as smooth as the iphone, its running a dalvik client

Do iPhone users just get Android phones and swipe and down all day to see how fluid it moves. You guys know there is much more to the phone then just scrolling pages up and down, right?
You also realize the device is pushing a higher resolution then an iPhone as well so a lot more pixels are in play.
Seriously, even if the GN scrolled smoother then it already does, I don't think I would really give a sh.t......It would not change my experience in the least.

Not to mention iPhone 4S GPU absolutely blows away any other mobile GPU on the market, and on top of that pushes fewer pixels.
iPhone 4S is a graphical beast.

Have you turned on Hardware Acceleration in the Settings?

of course its true, everything is in java

and of course don't forget about the fact that Android handles the UI in a different way compared to iOS (the UI isn't prioritised or something along those lines).

[Q] Project Butter

I understand that project butter was a feature of the newest android builds. Now does that mean when a phone officially gets the build they also get project butter? Is this only a nexus thing? If project butter is on a touchwiz rom, does that mean that it could lead to a faster cm10?

Its a jellybean thing. Any android with 4.1 or higher is supposed to have "project butter" its supposed to be 60fps now.

Yes, I mean that's what I assumed, I just mean to ask what could be holding it back? Is there a need for more development? Shouldn't the release of an official 4.1 release dawn the integration of project butter to all 4.1 roms?
I'm just trying to get a better understanding.

I'm confused, I told you its built into 4.1 ROMs we have it officially and unofficially through cm....

Project butter is BS. If you have a ROM and kernel combo with good performance and tuned properly without conflicting scripts anywhere in the ROM monitoring CPU.... or GPU... then you should never see a blip of "lag" ever.
Don't buy into the hype.

I agree its just a hype thing to get people excited and promote android for this and that. I still hardly notice anything different in JB compared to ICS, does it scroll better? a little. Doss it feel smoother in the app drawer? No. It feels extremely smooth still. Overall just enjoy your phone and don't worry about gimmicky names for things.

Hey, I read all of your comments, but here's where I'm confused... I know that disabling hardware overlays disables project butter, but wouldn't you want the GPU doing the work instead of the software anyway?

You will get better performance from the two CPUs "aiding" in rendering your UI... but the cost will be battery life. Honestly, an over clocked GPU can accomplish the rendering tasks in UI AND GAMES that your CPUs would. I have never noticed a difference in performance running my handset with the "disable hw overlay" ticked in the dev options.
Not sure what you meant by the GPU doing the work instead of software. Bottom line is, your hardware is doing the computing of what android (your UI) is telling it to do in either case. If you look at a kmsg log while touching your screen you can see finger touch events being communicated through the UI... touch boosters.. specific to jelly bean. Kind of interesting really. I guess this is part of "butter"
But like I said. Seems like a bunch of bs. I have never seen terrible lag in the last 4 devices I have owned - s3, 4g LTE, s2 and an Evo 3D.. and the latter two were running gingerbread!
Anyways, yeah. I type too fast. Lol

Project Butter is not bs. Flip through your widgets in the app drawer and tell me it doesn't feel a crapton smoother than it did on ICS.

So you want us to flip through our app drawer, Which I put money on 50-75% don't use stock to see if it feels a "crapton smoother" in the app drawer, I ran stock for a week without a separate launcher and nothing felt different...

I don't think project butter is really bs, have you guys ever used a galaxy nexus or the nexus 4? I've never used a device that smooth. My sgs3 is quick, but it's not butter. I think that that's what I want.

Smooth though
Having been on lots of ROMs I can say this -
Whenever I come across the system tweaks 'Project Butter',and they are ACTUALLY implemented, there NEVER is a corresponding increase in speed i.e. response to touch BUT over time, there is a definate velvety experience that I appreciate very much. Buffered almost. Fuzzy, like Vinyl vs. Digital.
There are many ROMs that are so quick, they feel twitchy...tense.
Anytime I'm OFF 'Project Butter' what I realise I'm missing is a certain finish to the 'beginning and end of action' - I'm miss a certain silkiness.
Over a period of time, I have come to actively look for these components first in ANY ROM - everything else can be APKed to fit my needs, but the overall feel of predictable, regulated, smoothness across the whole system is something that I have come to look for before anything else..

GNEX RUNNING SLOW !!help!!

Hello there new to the Gnex... OK here is my issue. I previously had an S2. On quadrant I was scoring 3600. My GNex is only scoring 2300 on a good day! I do not have a lot of apps, as a matter of fact I have the same apps I was running on my s2. I switched to the gnex for the pure Google experience and the plethora of knowledge on this forum. I've been scouring the different threads reading about all of the different ROMs and kernels out there all I want to do is to make my gnex as fast as the S3. On some other forums I was reading about the SUPER NEXUS which is an S3 rooted with the gnex software. Can you guys and gals help me to solve this issue??? I'd surely appreciate it. My apologies in advance I'm really not all that techy as most of you here but again that's one of the reasons I switched up to the Gnex because of the huge support base . Hey thanks in advance!
P.S. is there a swype gesture feature on this device? Or do I have to download swype? I find it most useful at times when I can't use both hands to type.

Dude benchmarks don't say everything about user experience, and especially not Quadrant. GPU on Gnex is slower than Mali-400 on S2. Plus it has bigger, higher resolution display and thus more pixels to push. It will always score worse than S2 unless you OC it.
Galaxy Nexus still provides great user experience but it cannot compete with todays flagships like S3 in terms of speed. It' a different league. No matter how you try u will not make tiomap 4460 faster than S4 Krait.

Making a GNex as fast as an SIII is simply impossible, you'd fry your hardware before you would even come close to the Quadrant results of that phone.
That being said, I have to agree with the previous reply, pure horsepower isn't everything, and I for one have never experienced any lags or slowdowns.
Then again, I keep my phone clean of anything running in the background, for example I only use ONE widget, and that also only on the Lockscreen (CyanogenMod's cLock).

I have a widget on every homescreen and device still feels snappy. Smoothness remains practically unaffected by those widgets.

I just picked up a Nexus and have been using it lately, I think it's fairly snappy for the age of the device. I was curious on the Quad score so I just ran mine and I'm at 2676 which isn't to hateful....no overclock just a custom kernel and rom

P.S. is there a swype gesture feature on this device? Or do I have to download swype? I find it most useful at times when I can't use both hands to type.

try using custom kernel like AK

^ive been meaning to give that kernel a try

Really you must uninstall that benchmark, do a lot of read and help yourself. I was a sgs2 user, and i am happy when i switched to gnex. The only thing that bad from this device is camera, s2 is better but i don't care.

Your GNex will never be as fast as an S3. It just doesn't have the hardware. With that said, benchmarks test a different set of the phone's capabilities relative to the way a normal user uses the phone. I would try out some ROMs and kernels, read up on tweaks for your chosen ROM/kernel combination, and go from there.
And swiping is in 4.2.1 and 4.2.2 stock keyboards. You might need to enable them from the Settings - Language and keyboard menu (I'm not 100% sure because I use Kii).

Want a really fast GNex?
1. Install CM10.1 latest nightly
2. Install Franco kernel
3.Over clock to 1.6ghz
4. Enable force GPU rendering
5. profit
You will get 54fps in epic citadel high quality and never lag. This phone may not "keep up" spec wise but there isn't a game or anything I can't run on this phone. Nothing can challenge my GNex

Galaxy S 4 Stutter fix?

The phone stutters often and it is frustrating! I just switched from the Galaxy Note II to the Galaxy S 4 and simple task like switching between home screens and application screens stutter. Third party applications run perfectly smooth. Face unlock has massive stuttering and I used it on my past devices just fine. The only thing I can think of is that it is powering a 1080P display.
I've been looking around online and all I seen were complaints or people saying they do not experience it. People who have what are some fixes?

The simple fact that you downgrade from the tw camera to the aosp camera is enough for me. Plus the fact that when you record video the volume is way lower. There was also a call bug that sometimes you or the other person couldn't hear each other ( I'm not sure but I think it was fixed). Cm was great for me when I had the Motorola Triumph since the triumph sucked, but cm has always had issues on all my phones that I've owned. Honestly people say it's so much smoother but I don't see a difference from tw and cm.

No bugs on my end. Could care less about the camera, and yes, the smoothness is apparent as soon as you flash cm. Anyone can tell you that. The only reason to go with TW is the features.
It just depends on personal preference.

I flashed the 4.3 Google Edition ROM and it is butter smooth along with the face unlock. So maybe it is not the 1080p display. I also noticed ram usage dropped by a good 50%. The TW ROM uses around 900mb-1.1Gb probably due to the bloatware that was on it. A Google Edition phone for only $580 I am happy.

It's apparently Touch Wiz that makes the phone laggy.I'm expecting Samsung to make this less of an issue with updates since it is a new phone but I didn't want to wait.
I flashed the Infamous rom since I am not willing to give up the Samsung camera features. Then I use Nova launcher within it and it runs much faster.

Horrible touchwiz is what causes the lag, flashed GE ROM. BUTTER SMOOTH, I don't use the Samsung gimmicky features and the only camera mode I use is HDR that's included in the GE ROM

I've had 2 M919 Galaxy S4's so far.
First one I returned because it was so incredibly laggy, everyone said theirs was butter smooth (all of whom were in denial), I thought I had a defective device. I tried all the custom roms using the Tmobile base and also international 9505 roms. Still did not fix the microstutters. Second one was laggy as hell also out of the box so I knew it was just the device. The latest international 9505 roms seem to make the phone smoother, but there are microstutters still present which should NOT BE THE CASE with a phone that's this powerful, but the biggest offender for me still is web browsing.
Open up the stock browser or chrome and go to theverge.com website, call up the full site and browse around. Pinch and zoom, then pan around. Tell me how incredibly slow it is to use. It seems like I'm using my original Motorola Droid all over again.
I'm sure by the time the Galaxy S5 comes around, Samsung "might" finally come out with a smooth working firmware for the S4, in the meantime I say ditch this device and get the HTC One. That baby is liquid smooth in EVERY operation and rips the S4 a new butt hole when it comes to web browsing smoothness and speed. Hell it even still supports full Adobe Flash even with 4.2.2.
The One is also pushing a 1080P screen so it's not the pixel count that is slowing the S4 down. It's something else. I had initially blamed the S4 lagging because of 4.2.2, reason is on my Note 2 running 4.1.2 it had next to zero lag and it's also running a heavy TW skin. I thought the HTC One was so smooth because it was still on 4.1.2. Well after updating to 4.2.2 on the HTC One, it even GOT SMOOTHER and FASTER.
I have also ran the google edition ROM's on both my S4 and my HTC One, and guess what?? The HTC ONE ran the pure GE ROM smoother than the S4 still!
The GE ROM still has slight microstutter on the S4 which is mind boggling. I noticed it a few times when opening the dialer and gmail app, the animation has a bit of microstuter in the animation when opening up. Something is definitely up with the S4 hardware wise.

[Q] Is my phone slowly deteriorating? (terrible performance)

Hello whoever is reading this,
I'm getting real tired of how slow my phone has consistently been slow for months now. I've tried a bunch of roms and kernels in combination, and while it seems to work smoothly after a clean flash, it slows back down to its usual laggy state within a few days (or even hours!)
I partially blame the age of the phone, as it's old processor probably can't handle all of the customizations being thrown at it that are really being developed for the Nexus 4. But aside from that, everyone in every rom or kernel thread is always raving about how "buttery smooth" or "lightning fast", or whatever else their phone is, claiming performance is awesome. It could just be that all those users are just used to some lag, but I'm really starting to feel like I'm the only one who has such performance issues.
For this reason I'm wondering if it's possible that something hardware-wise might be starting to die, similar to how "cheap memory is killing off Google Nexus 7". Is this possible?
Is there any app that can run hardware tests to check for things like that? I would love to see if my suspicions are correct or totally wrong. Is there anything else I should try?
I'm currently running the latest ak47 rom (AOKP Milestone 2 on top of VANIR (linaro), and using Fancy Kernel. I've found the performance is pretty good compared to other roms I've tried but I still find myself waiting seconds for the app drawer to open, to scroll through pages in the app drawer, etc.
Any help would be much appreciated. Thanks.

Hmmm... if it is anything related to what was happening with the Nexus 7, then you've probably heard what Android 4.3 did for it. I'm writing this from my Galaxy Nexus, and it hasn't been faster since 4.1; whatever 4.3 did for the Nexus 7 has a similar effect on my GNexus. It took a couple days, but I have my butter back!
Before the update, I was in the same boat as you. Even the keyboard was ridiculously laggy. Now? Buttery. Not Nexus 4 buttery, but buttery.

Hmmm... if it is anything related to what was happening with the Nexus 7, then you've probably heard what Android 4.3 did for it. I'm writing this from my Galaxy Nexus, and it hasn't been faster since 4.1; whatever 4.3 did for the Nexus 7 has a similar effect on my GNexus. It took a couple days, but I have my butter back!
Before the update, I was in the same boat as you. Even the keyboard was ridiculously laggy. Now? Buttery. Not Nexus 4 buttery, but buttery.

I didn't hear what 4.3 did, but I gather that it improved the speed? Sweet, maybe I'll try that. My issue is I'm too addicted to AOKP
But I'll have to try a stock 4.3 rom or something and hopefully I'll find the same results as you. Thanks for your input!
My question about an app that runs hardware integrity tests still stands.

No problem! And it provided a lot of behind-the-scenes improvements for graphics processing. It also made FSTRIM turned on by default in the system; it will run whenever the battery is above ~70% and the device is idle. It basically stops the device from needing to perform multiple actions in the storage whenever it needs to read or write. You only notice the effects of it NOT being present over many write cycles, which is why performance may seem to have deteriorated over time.
And yeah, custom just gives you so many choices! But a few days with 4.3 should REALLY ramp up your performance. It takes a little while for FSTRIM to do it's magic. App drawer opens after 0.7 seconds or so, and swiping between pages is quite fluid and responsive.
Glad to be of service! Hope it helps out.

Aside from 4.3, I've found that if you goto Developer options, and lower the Transition, Window, and Animator scales from 1x down to .5x things seem to move more smoothly. Albeit they only reduce animation times, the visual effect may be enough. I also use Nova Prime launcher and turn animations to "Nova" speed. Things like the app drawer open instantly. Absolutely zero lag. What I'm running is in my sig...

Hello whoever is reading this,
I'm getting real tired of how slow my phone has consistently been slow for months now. I've tried a bunch of roms and kernels in combination, and while it seems to work smoothly after a clean flash, it slows back down to its usual laggy state within a few days (or even hours!)

Any help would be much appreciated. Thanks.

This frustrated me for a long time until I came across this app (root needed):
LagFix Free: https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en
XDA thread: http://forum.xda-developers.com/showthread.php?t=2104326#fm
"Some Android users suffer from poor performance after some days/weeks of heavy usage. This is due to a well-known TRIM bug affecting these devices. The source of the problem is that internal storage is not properly TRIMmed when needed. It is also well-known fact that running fstrim Linux tool from time to time fixes the issue until internal memory runs out of free blocks. LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily."
Android 4.3 finally implements this fix, so if you go a 4.3 ROM, you won't need this.

Yep, like they all said, 4.3 fixes that with things like TRIM, and I can attest to that firsthand.

I must say that the phone is faster on 4.3, but my battery life is horrible when comparing to 4.1.1 or even 4.2.2, especially when using the phone.
I don't know if it's true or I'm too bugged about it. Could someone please confirm it to me?

I guess it's just bad luck haha.
Gonna test it calmly to be sure.
