[Nexus 4 Q&A, Help & Troubleshooting] Mubz_C:
Just my two pence (might have been said before) the reason I think as to why there is scroll lag is because the apps themselves aren't optimised for specific android devices in general. Let's take apple for an example. If you have to make an app for apple iphones you only have have a maximum of five devices. Therefore you have more time to work on the app for the individual device. Then when you making an app for android you first have to look at what android version you are making it for. Since over a quarter of android users use gingerbread or lower the big apps have to be suited for those devices. (Correct me if I am wrong) They have also have millions of devices to work for and they probably going to have a deadline. So the developers cut corners and don't work as much on a specific device as they would for apple. Try using a android 4.0+ app and that should have less lag on android 4.0+ devices. Less devices to work for so more custom tailored apps.

Its those people whining and complaining that has enabled us to have a hardware accelerated version of android. I don't understand why people expecically android fan boys (fastmajority of them) are so defensive.

The more complain, the more improvements the responsiveness, the more lag/stutter free devices we'd have in the future.

No input lag on iOS? I confirm that its wrong. It does have input lag like 2% of the time. Modern day androids are a lot better from 100% input lag on gingerbread days to around 10-20% today

Some apps do not have smooth scrolling enabled, that is to do with code on that side.
[Nexus 4 Q&A, Help & Troubleshooting] MrAndroid12:
Force hardware acceleration in developer settings does the trick through its more to do with (graphically related)layers and its complexity. The Facebook app for example (before recent update) loads the device's GPU to maximum causing lags to most of last years flagships but the nexus 4.
[Nexus 4 Q&A, Help & Troubleshooting] sxi200:
Using the S4 and scrolling lag had been a pain since the S3 for me. Haven't used s nexus. On the S2, S1 and galaxy tab scrolling was a breeze. Forcing gpu rendering speeds things up but then it suddenly disappears. Turn it off then it speeds up again only to slow down soon after. Doing my head in. It takes numerous flicks of the screen just to go from one end to the other.
[Nexus 4 Q&A, Help & Troubleshooting] MrAndroid12:
Compare a windows phone, surface or ios device and you're know.

Android has a very annoying tendency to stutter a few seconds before having some smooth scrolling, scroll smoothly and then having some frame drops or just jerky all around (tap tap revenge for instance with its buy track page)

Don't feed the iPhone fanboy trolls!!!
[Nexus 4 Q&A, Help & Troubleshooting] fade2black101:
Android fanboys (fandroids) are just as annoying as iOS fanboys. Infact, I don't go on any iOS centric forums so fandroids personally annoy me more than iPhone "fanboys"

Nevertheless, they're both pathetic. iOS has smoother scrolling than any Android device. Get over it.
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
Personally, I don't care. I don't go to iOS forums and those fanboys here are just here for the feeding. Hence, I say don't feed them. Everyone is entitled to their own opinion, even if it is wrong.
[Nexus 4 Q&A, Help & Troubleshooting] fade2black101:
Which fanboys are you talking about? L
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
Any of them. I prefer Android, but my joy is the fact that I can openly mod and theme it. I also love being able to have widgets. That makes iOS useless to me. I could care less about ever so slight scrolling lag that is really not even noticeable with day to day usage. If you look at the the title, it says all android apps have scroll lag. I find this not to be true. There are some apps that have slight lag on my device, but most don't. Who is to say that if you were to start throwing some widgets on iOS, it wouldn't choke on them and create some lag with the OS? Just look at some of the issues iOS 7 has brought and it still doesn't have the customization ability you get with Android.
[Nexus 4 Q&A, Help & Troubleshooting] fade2black101:
I prefer Android too, and I prefered windows mobile too when it was the most horrible looking and laggy OS around.

Now, I'm not really bothered about theoretical questions about if iOS had widgets, etc. If Samsung could be bothered to refine touchwiz, then maybe a quad core beast with shedloads of ram wouldn't lag out when, for instance, scrolling through contacts or text messages.

You seem to be suggesting people in this thread who are pointing out the truth must be iOS fanboys.

Obviously not all apps on Android lag when scrolling. But a lot do. Especially in comparison to iOS.

So I put it to you, is iOS in general a fair bit smoother than Android? I prefer Android, but I say iOS has much nicer scrolling and this is something that Android should really sort out and make more consistent.

Does this make me an "iOS fanboy troll," or does it make everyone in this thread who suggests otherwise a liar?
[Nexus 4 Q&A, Help & Troubleshooting] 350Rocket:
I never said that ios 6 on the iphone 4s lagged more on the Facebook app than my one s, but I guarantee that it was not 60fps all the time. Maybe most of the time but not during the little stutters that I saw from time to time while she was scrolling. Same thing as on my phone but not quite as much.

So call me a liar whatever, just saying what I saw with my own eyes.
[Nexus 4 Q&A, Help & Troubleshooting] fade2black101:
I wasn't calling you a liar. (if your post was directed at me)

Not sure if it was 60fps all the time. I doubt it was. But it was definitely noticeably smoother than any Android device I have used or am using right now.
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
Obviously, there was a time when iOS was further ahead and ran a bit more smoother with less lag than Android. Today, the difference is so slight that anyone that says otherwise is just exaggerating it. And this could vary with different apps. My experience with iPhone is minimal but I am familiar with it as it has always been the phone of choice for my son since the very first iPhone. At the time of release I considered iPhone cutting edge and never tried to deter him from it. I myself was using Windows Mobile at the time. Since switching to Android, I have been growing with it. Interestingly enough, these days, I here more iPhone users griping about their phone than I do Android users. Not always about lag and freezing, various things. Lately, a lot of battery complaints. Something that has always been reserved for Android users. Imagine an iPhone with a 5" screen size. There surely would be max battery complaining from users of that phone. In the end, it is always about preference and trade offs. Honestly, I really don't mind something that is virtually non existent these days. I don't do any hardcore gaming, so day to day, my phone runs silky smooth.

Performance mode is just maxing all online cores at 1.5GHz, android shouldn't have to do that just to remove lag.

Try official Facebook application... I think it is the worst and you should be able to tell....

Instead of comparing to older devices 3GS or iPhone 4, compare to iPhone 5.

Nexus 4 is the smoothest Android phone no doubt. I think it is better than even the new S4. But to compare with iPhone 5 or those Windows Phone 8 devices (Like Lumia 920), it will lose....

We are not talking about launcher lag. Home screen scrolling and app drawer scrolling are now really really smooth on android even with stock launchers. But a launcher has nothing to do with in-app scroll lag.

Trust me using RasSaber or SaberMod lag is reduced by a lot! Tapatalk hardly lags any more, my SMS messages, one particular contact I've got over 12000 messages with scrolling through those messages is a breeze. The toolchain used in these roms significantly reduce lag.

Android at times can be poorly optimized to the hardware. But devs here take care of that.

By using the 2 mentioned roms I have never ever experienced such speed on any Android device, it's smooth and awesome!

I'd make a video and show you how scroll is on these roms but my upload speeds are very poor.
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
This is strictly graphics rendering. With previous devices there was limited hardware acceleration. Since ICS, there is now full hardware acceleration, but it is up to developers to implement the use of it. Since the iPhone had full acceleration first, it is likely most of the apps in the store are already making use of it. It should also be noted that Android is spread across multiple manufacturers, models, and CPU's, while there is basically only one current model of iPhone at a time, making it more challenging for Android. In addition, the screens on Android phones continue to grow larger and larger, while iPhone continues to maintain a small screen. I also find FB and Tapatalk as the worse culprits of rendering lag.
[Nexus 4 Q&A, Help & Troubleshooting] beegbear:
the scroll lag for me is actually worse in Whats App than Facebook, which seems to actually run quite smoothly. I have ZERO scroll lag on text messages
[Nexus 4 Q&A, Help & Troubleshooting] XxVcVxX:
You know, Facebook is a poorly written POS, and basically every other app that has scroll lag can just turn on GPU rendering. Doesn't break apps as well.
[Nexus 4 Q&A, Help & Troubleshooting] drakester09:
Exactly, some people here in this thread with zero programming knowledge blaming the OS for poorly developed apps. :p

[Nexus 4 Q&A, Help & Troubleshooting] Gambler_3:
Yes clearly devs of whatsapp, viber, tapatalk, twitter, etc don't know anything about development and yet the same devs seem to know very well about iOS and windows development. ;)
[Nexus 4 Q&A, Help & Troubleshooting] drakester09:
Having a successful app does not mean it was crafted or developed with quality.

- Whatsapp performance greatly improved on the latest app redesign.

- Viber, never used it, can't vouch for it.

- Tapatalk, I use it every day, and I can vouch for it not being optimized, poorly implemented last time I read about it. Extremely useful though.

- Twitter, latest redesign sure improved things, but in general Twitter official clients are a good example of 'do it everywhere, master none', see Falcon Pro for a good Twitter client example.

I'm not discussing other platforms in app quality comparison, it's a moot point since they might have been developed by different teams or more resources allocated to those projects. Common for iOS apps to have more focus.

Edit: do you have any other device than a Nexus S, where you have tested the lags?
[Nexus 4 Q&A, Help & Troubleshooting] norpan111:
I was using a Lumia 920 before I got my n4, my wife has a iPhone 4 ...my n4 runs circles around those! Wp8 has some really slooow transitions animations you can't to stuff as fast as you like it. Try the new Facebook beta(yeah I know beta but anyway) and the new YouTube apps on a powerful device like 920...they are really laggy! And Microsoft themselves developed this apps! I'm really amazed how not only fluid my device is but how fast I can operate it...both iOS and wp8 decides for you the pace you are able to work, its like playing a poorly optimized game with vsync (slow response) and blazing through with 100fps with some tearing perhaps but with precision and control

Use whatsapp on windows phone its completely smooth. The android version still lags when you scroll through your contacts, clearly its an OS issue not dev issue.

Can you name me a single third party app which has absolutely no scroll lag?

[Nexus 4 Q&A, Help & Troubleshooting] meangreenie:
I'm viewing this page on aosp browser and it scrolls around like a pane of glass and without even the smallest of hiccups, I had to tune the on demand governor to get that result and now my phone never lags/jerks in any app I run... apart from the new Google play store app because it was made by clowns.

I can't test whatsapp contacts because I don't have enough entries to scroll the screen lol, but the main chat pages scroll like glass for me too.

Another 'acid test' is 'temple run' original version.. If it doesn't glide faultlessly then the governor is capping the frequencies too quickly imo.
[Nexus 4 Q&A, Help & Troubleshooting] exb0:
I agree with the OP. Sometimes it does lag once in a blue moon while scrolling. Even on my n4. I tried WP7.5 or something on my HD2 and I can tell you it is HEAPS faster. The problem is that all the apps for windows phone is badly coded. Even with the lumia 920 whatsapp lags like a little biatch.

With that said, I'd rather have a little scroll lag than get poorly coded apps.

Apple and MS vet apps before they allow it on their stores. They won't approve something that stutters badly. There is no such thing with Android and devs can push non optimized apps.

[Nexus 4 Q&A, Help & Troubleshooting] prince93:
Came here from a Google search about Facebook app having scrolling stutters.

I think too android have issues with scrolling, and I don't know if it's an OS issue or just apps?

I have galaxy tab 8.9 (cm10.1), and while I have absolutely no stutters when scrolling in the stock jellybean browser, I have a lot of stuttering when scrolling through Facebook timeline using the official app and also Google plus. So, I really wanted to know what is the difference in the scrolling method or engine used when scrolling in the stock browser and when scrolling in the social apps mentioned above. Is it something related to android or to a specific device or to the method used for scrolling ? Is it something that needs to be addressed b Google in new iterations of the OS. I really don't know and I hate the stutters very much that I can here the whole android os for it. What is more surprising, that I tried the Facebook app scrolling thing in gs2 and I didn't feel the same stuttering I get even though the hardware specs on both devices are comparable.
[Nexus 4 Q&A, Help & Troubleshooting] maaaaz:
I think OP is trying to say that, compared to iOS, Android graphics suffer inexorably from lags.

This is something true as these OS do not share the same internal structure : iOS has a special thread dedicated to graphical stuff whereas Android does not have such a process.
[Nexus 4 Q&A, Help & Troubleshooting] shinodoigt:
So I'm not the only one noticing this, it's a good feeling. I was comparing scrolling performance with a coworker the other day, on the LinkedIn and Facebook app. The difference is pretty huge : even when app is loading data like social media apps, scrolling doesn't lag on iOS, it's stuttering quite a bit on Android. I've CM 10.1 with franco kernel, it's heavly optimized.

Try Foursquare app, it's the worst in my case. Google+ seems to suffer less stutter than other apps.
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
No, I don't use that app, but if scrolling doesn't stutter with the stock contacts app and does with a different third party app, how can we blame the operating system? As I posted before, with some apps, hardware acceleration does come into play. iOS implemented hardware acceleration prior to Android and is ahead of the game with most apps in the store making use of it. Google has been playing catch up, but now has full hardware acceleration and I have a feeling some of these apps are not fully written to take advantage of it. Also, with Android, I see where users are constantly clearing their caches. Does this not force graphics to have to be constantly reloaded? I get a bit of lag with this tapatalk app, but I notice it is when I first open or scroll thru a page. Once it is loaded, I can scroll up and down with no lag.
[Nexus 4 Q&A, Help & Troubleshooting] Gambler_3:
The stock contacts app is a system app built into the OS you know, are you really trying to say that EVERY app on the play store is not doing it right and all developers are clueless? Do you even realise google apps available on play store have scroll lag as well?

Comon android got HA with ICS which is now 1.5 years old, lets not kid ourselves its clearly a problem with the android OS.

And yes you are right apps dont always lag with scrolling but why should they even first time? It doesnt happen on other OS. And there are some apps including google currents that will pretty much always lag if you try to scroll really fast. ALL social apps on android suffer lag when images/text is still loading and you try to scroll.
[Nexus 4 Q&A, Help & Troubleshooting] fernandezhjr:
I can take that system contacts app and make it a user app rather easily and I doubt it will lag. Now, if there is a problem, it is barely noticeable on my device. Now, I'm not gonna deny getting some slight lag with certain apps, but it is not near enough for me to whine and cry about. I have seen worse on previous devices that run Sense and Motoblur. I can't speak for Touchwhiz because I swore off of Samsung long ago over the crappy devices they used to put out. As far as this device, it is easily the smoothest running stock device I have had and as far as that goes, I put it right up there with the iPhone, which I do have experience with. When I take other factors into consideration, like the puny screen and having to be married to iTunes, I would easily choose this device over it.
