Desktop scrolling smoother after root?

Hey Folks. Just wanted to know if anyone else has experienced this after rooting. After root I thought it might have been a placebo effect, but my desktop scrolling is definitely smoother. I'm not saying that it flies, but it definitely takes less effort to swipe and there's less lag. Anyone else?

I believe I'm experiencing the same effect. ESP with my keyboard lag being better. Could just be a plecibo effect. Or the factory reset as opposed to root actually doing anything

The answer is no (rooting is just a file on the filesystem)

No relation (unless you did some modification).
You are experiencing placebo.

i think we're just getting used to the speed. going back to my tf and i notice how fast it feels now.

there is no way for rooting to affect performance. what will make the lag better is when we start seeing custom kernels and custom ROMS. The tiamat kernel running at 1.4Ghz completely eliminated lag on my XOOM.

Placebo effect it is then...I still think it's gliding along better though

Nahhhh After playing with an iPad today at the mall it makes my former Asus and current Samsung seem like molasses left outside in the Alaskan winter for 3 weeks! It's shocking how smooth IOS is vs. the competition but I still prefer my Samsung (admittedly I do have an iPhone but can't stand Apple as a company).

This is exactly how I feel.

The iPad is smooth and fluid because it isn't doing anything. There's no real multitasking or things running in the background. No widgets. Etc. It's easy to make an OS run smoothly when it's only doing one thing because it's so locked down.

Nexus 4 Input Lag

Hey Guys,
ever since i use Android im kind of annoyed by the responsiveness of the tochscreen. Even with state of the art smartphones like the S3 (ICS version) there is substantial lag. (compared for instance to an iphone)
I was really excited when JellyBean was announced because as it seems, it addresses the issue.
However when i tried an S3 with JellyBean i still felt the lag.
My question is whether the Nexus 4 actually matches the Iphone in responsiveness.
(I do not mean the stuttering when opening for instance the app drawer, i mean the pure relation of the finger touching the device and the quickness of the response of the device.)

It uses the same new technology as the iPhone 5 which brings the touchpanel closer to the front glass meaning responsiveness should be significantly better. It's called In-Cell Touch display if you want to Google it.

You'll get a real answer when the phone comes out. Or check video reviews. We know as much as you do at this point.

Thanks for the answers enviii and ralexand!
The thing is, this input lag issue is very rarely adressed. It seems to me as if most poeple dont even notice it. It may be that im kinda picky there but its definitely a very important feature for me...

As the device has been released I would appreciate someone talking about the mentioned issue, who actually posseses the phone.

lol... that's just not true. It helps viewing angles, but has absolutely no effect on responsiveness.

The thing is, It could be or could not be,I think its just what peoples definition of smoothness and response is. Never know until the phones out. IMO

Well for me the scale is definitely the iphone. (even still the 3G when scrolling homescreens) Also top notch Windows Phones offer very good responsiveness.

I guess it would be better for you to stay with iPhone.

EDIT: Deleted

iPhone relies on a system that basically delivers all or much of the available resources to the graphical interface when scrolling, which slows down or stops whatever else the phone is doing at the time (ie stops loading a web page when you start scrolling or momentarily pauses a download). This, along with a very strong GPU, is much of the reason for the smooth interface. (note: this info was taken from an interview with a Google employee, probably about a year or less ago. Could be outdated, but I believe it's still true...)
4.1 ramped up graphics rendering FPS to 60fps. This, a long with a strong GPU, S4 Pro processor and (mainly) 2 gigs of ram should result in an incredibly smooth UI. Also, the curved glass on the edges of the screen have been noted to give a much smoother feel to scrolling, whether it's a placebo effect or not will just have to be determined over time.
Long story short...yeah, this thing should be smooth as butter (pun intended)

Also iOS is more optimized since its on for few devices.

actually the big main reason for smoothness of ios vs android is that...every single application (basically everything) runs on virtual machines on the android unlike ios.. so it is true that the beefier the hardware the smoother the device..and thats y ios is able to run smooth even with lesser hardware..

Thanks for this in-depth information. I have already known some of this from posts by google employees on their google+ pages.
I hope the changes introduced in JellyBean and the sheer performance of the Nexus 4 can overcome the innate performance issues of Android.
When someone has made first real life experiences with the device please let me know

I have a Nexus S (awaiting a 16GB N4) and I can tell you that Jellybean offered a tremendous improvement in smoothness.
As for the lack of improvement with the S3 and Jelly Bean, do keep in mind that is not "stock" Jellybean, Samsung may have avoided using any of the "project butter" code for their own GPU rendering.. Only Nexus devices are guaranteed the advertised improvements listed by Google, once an OEM touches there's no guarantee.

Only the framerate is high. There is MASSIVE input lag of 100-200ms on every Android device. As evidenced in every video of the Nexus 4 the screen lags behind your finger by 1 inch or more when swiping. This makes it feel extremely sluggish and unresponsive in apps like Facebook and games like Canabalt are unplayable.

I noticed this too when I first started messing around with my N4.
A test I like to do is use the calculator, and see how many numbers I could hit before they would be highlighted (which I assume means the device starts registering the command). For some reason I was getting 2 (almost 3) punches before the device would see it. On my Wildfire S and my iPod Touch the input lag was never this bad.
Amazingly, I actually found a solution. I don't remember if I turned it on myself or if it came on by default, but my phone had the "Magnification gestures" on. You can find them in the "Accessibility" settings. I turned it off, and BAM! The input lag has practically disappeared. I don't know why it was doing that or how it's related, but this has effectively fixed it for me. There may still be a slight input lag, but it's small enough that I can ignore it. Before it was easily over 500 ms.
Hope this helps.

I've made sure that's off on every Android device I've tested. The input lag is still considerably worse than the iPhone.

So I have an HTC One AND a Galaxy S4 now...unbiased observations between the two

I just wrote this this thread to humor myself and anyone else who cares or is interested in comparisons between the two phones. I'm coming from an HTC Sensation which I've had for about 2 years, previously owned the og Galaxy S (Vibrant), and instead of the S4 I chose the HTC one, and got the GS4 for my wife instead, and use both on a regular basis.
Here are my observations since I actually have both phones and can compare them with no bias...
-A lot of the online mainstream reviews you'll read between the two hit the nail on the head. The One imo is a better "phone". It does indeed have less features then the S4 (although many of them are gimmicks like the eye scrolling/tracking, airview, and a few others) but the speakers are far superior, which obviously aids for anyone who ever uses speakerphone or plays music and videos, the call quality is also a little better, the phone is more fluid and faster than the GS4 with basic functions like scrolling screens etc, and the phone of course has a MUCH more "premium" feel. Sense 5 is MUUUUUCH better than past versions of Sense and like a lot of review say, it *DOES* improve over stock android in actual useful features. The look is subjective of course but it's flat, useful and fast, and to me that's all that matters. The camera is better than any past smartphone I've ever used (Tmobile Dash>G1>Vibrant>Sensation>One) so I like it personally, but compared to its rivals like the GS4 I guess it's not the best, but does everything I've ever asked of it VERY well so no complaints from me.
-The GS4 on the other hand has a superior camera. The camera on the One isn't bad at all, and kills the Gs4 in low light conditions and the aspect ratio and wide lense captures waaay more in each frame, but the GS4 has more camera features, packs a crapload more detail in each shot, has some pretty useful camera modes the One doesn't have, and is just generally better. The Galaxy might not be made of aluminum like the one, but it's lighter and imo actually feels better in my hand (without a case). Once you add a case in the mix, hand feel is null and void obviously but if you like to go commando the Gs4 feels better and will probably hold up to abuse better than the One due to the polycarbonate body and gorilla glass 3. The screen on the Galaxy is bigger than the One while the actual phone altogether is lighter and smaller so that's pretty nice, but it's not really THAT noticeable to be honest. One huge, huge advantage the Galaxy has over the One is removable storage and battery, which *USED* to be a deal breaker for me back in the day, but I've learned to live without them since I got my One, so either way it's a definite advantage but I guess how much so is up to the user. The Galaxy also has native quick settings built in which the one doesn't have (yet), so minor issue but another positive for the galaxy.
As far as negative for each, I'm actually on my second One already. Somehow my camera lense glass cracked even though I keep the phone in case and have never dropped it or bumped it. It just appeared one day in addition to the top speaker grill starting to separate from the body. Weird, but I got it replaced and the replacement is doing fine and actually stands up to overclocking and undervolting better than my old unit, so that made me pretty happy lol. That's really the only issue I've had with mine, but on the whole, the phone is definitely more fragile than the Galaxy WITHOUT a case. It scratches easier, dents, chips, etc...while the Galaxy doesn't.
The Galaxy feels better in hand (caseless) than the One, but it's slippery as hell and slides around easily and can be more prone to being dropped. Again, only an issue without a case, but this is my observation.
Touchwiz...personally I think it's a mess. I don't care for the look, as many have said it feels like your still running Gingerbread 2.3. The look hasn't changed much since I had a Vibrant running Touchwiz from 3 years ago, and while Touchwiz DOES have some unique features and generally does more than Sense and stock android...it's just ugly as hell while doing so lol. The Galaxy also does feel a tad slower and microstutters every so often while the One is almost always fluid and seems much smoother even tho it's running a newer version of android and has slightly better specs on hardware...it just doesn't "feel" like it. Other than that it's a fantastic phone and we haven't had any problems with it whatsoever unlike the One.
Between the two...if I just had to pick one, it's a toss up. I prefer my One honestly but I can see the advantages of the Galaxy S4 with it having more features so I'll just break it down like this...
Usefuleness as an actual phone
One>S4
Camera
GS4>One
In hand feel, portability
One=GS4
Usefulness as a multimedia device
GS4=One
Expandability
GS4>One
I will say that between the two if this even matters to anyone...I get WAAAAAY more props and questions and even jealous stares directed towards the One.........although..........people tend to ask to let them play with the Galaxy S4 quite often lol...

This is going to be TLDR post
I think now I have owned all 1080P phones from mainstream manufacturers and Oppo.
DNA, Xperia Z, SGS4 and One.
Could not live with Xperia Z, unacceptable compromises on a flagship device. Sold DNA as well and now with SGS4 and One (And Oppo find 5 as well, but that purchase was of oa curiosity purchase )
Both have their niggles to be honest at this point. But as far as one is concerned, I am not going to live with Sense 5 in its current form. I just cant. I will keep complaining about blink feed until HTC fixes it to add custom sources or more sources comparable to Pulse. The social media capabilities of blink feed are irrelevent to me as I dont use facebook much and for twitter which I do use, it does not even comes close to functionality of Falcon Pro.
Then the caveats with app drawer, lack of options to change wallpaper from home by long pressing also gets on my nerves. Having to go through 3 steps extra to change wallpaper is just silly. So I had to resort to custom launcher which has its own share of problems due to the fact that for some reason lot of launchers are not butter smooth on One with MSM DCVS governor as well as not as smooth as Note 2 or Nexus 4 even on default On demand governor. For those who have not actually experienced what butter smooth experience means on these device, it appears smooth. My sis who came from SGS2 thinks its smooth. I can feel the jitter in UI and that is really disappointing. And it has something to do with governor and / or kernel as there are issues with jitter and microstutter in 2d arcade games like Hill climb racing on One when the same game runs just fine on older Krait 200 CPU on Oppo Find 5. I got Go launcher to be most close to what I want by adjusting animation speed. But it is still not as perfect as I want it to be.
That and menu button even when mapped to long press back using custom rom does not still behave perfectly 100% of time. Sometimes it just goes back. But I have learned to live with that. But these are notable niggles.
Camera issues I had with older camera are now fixed. I am happy with One camera results now.
The only other bugs that annoys the hell out of me is the contact bug that was there is Sense 4 as well and it is there in sense 5 as well where Sense decides to save new contact to my other gmail account than my primary account even when the second gmail account is not even set to sync contacts. Every time after installing new ROM clean I have to click on Google tab and select my primary account before hitting save.
SGS4 TWUI might be visual mess but it is very functional. Everything just works as it should on Android phone. The actions are not that far away from what we get on stock android. So even with Samsung plastering entire colour spectrum all over, everything works as I am used to. No surprises, no irritating faults. I dont might extra features. I have half of them disabled and bloat removed.
The power saving features on Exynos Octa does not seem to work properly yet, or not as good as they are suppose. The product was clearly rushed, but I guess it will be SGS3 story all over again with Samsung fixing most issues with unofficial leaks over coming weeks and with final release fixing this on OTA for those who dont want to experiement. I have that much faith in Samsung now.
Hardware I leave it to the users but SGS4 does not feel like cheap plastic. Sure it does not feel as premium as HTC One, but that typical BS people on forums and even some press spreading about SGS4 feeling cheap is just plain BS. It feels good in hands, it feels as premium as Note 2 and Note 2 did not feel cheap at all. Specially not in white colour. Rest is upto end user to decide but if you get the chance, do see S4 in person. It is great device to hold and use. With right case which I always use no matter what phone, it is not going to be an issue at all.
Coming down to personal choice, I am still using One as my personal daily driver and S4 as work phone. The bigger real estate on S4 does come in handy though and I have a feeling that in the end it is going to be better overall device to use for media consumption for someone like me who do not listen to songs or watch videos without using headphones. I dont like to watch videos even at home with the Ones wonderful speakers as I dont like disturbing my family members, and specially my hyperactive dog that just wants to get its head between me and my phone to investigate what sound is coming out of this weird device if I play anything on it using loudspeaker So really I am wasting the speakers on One. But that can be big selling points to some. For me, it is nice thing to have but I like to use phone strictly for personal media consumption and not broadcast it to others, neither do I want to disturb others at night in bed when I usually check up on some youtube videos from my subscribed channels.
The bigger real estate also helps a lot in gaming.
In the end S4 has less niggles at the moment. HTC has chosen risky strategy with Sense 5. People will either love it or those like me who simply hate it. I replaced it with custom launcher. Lot of people still love it but plenty are going to be frustrated by it. I never likes less options or restrictive behaviour on any android phone. That is exactly what HTC has done on their stock sense 5 launcher.
UI functionality is as or rather more important that UI design and feel. Sense 5 feels smooth and polished but it is very restrictive in nature and feels like HTC have done some things deliberately different just for the sake of being different without thinking logically if they really needed to do those things differently.
It is case of "So close to perfection, yet so far" with One. It is wonderful device. Good enough for me to be ready to live with the cavates it has. But sometimes I feel like switching to S4 as primary personal daily driver. But the beauty of this device is what keeping me from ditching it. That is ultimate thing in favour of One. But frustrating thing is, it could have been so much better with just few changes.

Thread closed
This thread is another sad example of the reason why we do not wnat any comparison threads here. Although the OP had the best goals with posting it, some fanboy users can't refrain from using it as another battle ground. Deleted 15 posts (some of them NOT being unfair, but I treated all equal)
So thank you OP for the comparison. It stays here as it is helpful. The rest of the discussion is not.

Touch screen lag demonstration

This is for demonstration purposes. If you see the same amount of touch screen delay on your own Moto X Play's, than this is not a defective device. Post a video of your own device demonstration if you would like to contribute. This 100% contributes to the sluggish feeling UI. For comparison, I have a Galaxy S5 running CM12.1. Can you tell which one has much less delay? If not, that would explain why we have such a difference of opinions in the community right now.

Nice, mine in worse but I won't take a video
Funny how touchwiz is faster than almost stock android

I think he said that the S5 is running CyanogenMod 12.1, not TouchWiz.
Anyway, this comparison doesn't surprise me. The S5 has around 3/5 the touch delay compared to to the X Play. Out of curiosity, I tried the same comparison with my X Play (lux) and 2014 X (victara). Hardware wise, the victara is essentially the same as the S5, and software wise both are running ROMs fairly close to AOSP. As I expected, the comparison results were essentially the same. The victara had around 3/5 the touch delay of the lux. This makes perfect sense, given that the MSM8974's single core performance is nearly double that of the MSM8939.
As to whether or not I consider this to be a caused of perceived lag, this is where I disagree a bit. Some people are more bothered by this type of latency than others I suppose. In real world usage, I personally don't notice if a page is a few millimetres behind my finger when I scroll, so I don't consider it to be laggy in my opinion. To me, I consider lag to be cases where the phone pauses and I wait for it to do something. I also consider choppy (low frame rate) animations to be bad. I haven't experienced much of either of the two things I consider to be lag. The only thing that bugged me a bit was low frame rate in the animation to drag down the Quick Settings drawer. I recently enabled the developer option to force 2D GPU rendering in CM, and that animation seems to have gotten significantly smoother (or at least more consistent; it used to be smooth sometimes and choppy other times). The frame rate is still visibly lower than my victara (this device has 1/3 the GPU power), but at least it isn't annoying now.

Scrolling Stutter

I'm considering buying a OP6T but I have one worry. I bought a OnePlus 6 when it came out and it had horrible micro stutter when scrolling through lists such as the Settings app, XDA, Facebook (I know it's not the best app, but still), etc., So what I'd like to know from some people who have the device, is can any of you see any kind of stutter when scrolling through lists? Thank you.

I'm extremely sensitive to this kind of issues (the reason why I left Samsung), and I have to say : OnePlus is the smoothest software I've seen.
My 6T's scrolling is buttery smooth. I believe 99.99% owners will say the say thing. The 0.01% left are probably users with bad habits using bad apps.

Thanks for the answers! I've played around with one at a T-mobile store and it had the same behaviors as the 6 I had. Maybe there was something in the Settings causing that. I've read that gesture nav can cause it, but I'll go to another store and see if it's the same. It's between this phone and the Galaxy s9 Plus for me because I really like Samsung new One UI, but I don't wanna wait forever for updates, so I'm trying to make the best decision because I'm really sensitive to scrolling stutter. And who knows, maybe an actual device won't have the same problems cause I'm pretty sure those display devices don't get any updates, updates may have helped.

I am usually sensitive to scrolling stutters as well... But my 6T is definitely smoother... only place I find stutters is in playstore..but that's with any other phone as well...
