Laggy Scrolling?

Is anyone else experiencing this? On web pages or long lists, scrolling around is not nearly as smooth as it should be. My brother has a Hero, and the Evo is not as bad as that... but it is nowhere near as smooth as an iPhone is. If I scroll around quickly, it gets pretty jumpy, where the frame rate slows down a lot. I read another thread (maybe on a different forum) where people claim that it's just the difference between the speed of scrolling and/or the "coasting" feature of the phones, but this is not what I'm referring to. I'm referring to mainly the frame rate of scrolling around and also the lag between when my finger moves and when the action takes place. It is most apparent on bigger web pages and long lists (like the Manage Application list). But it also does not happen all the time.
I have Advanced Task Killer running too, set at "Crazy" and the kill frequency set to "When screen off". Is there anything else I can do to make scrolling smoother?
I'm sick of having my friends who have iPhones playing with it, and immediately commenting on how it's not nearly as responsive.
Any ideas?

I played with an EVO in the Sprint store yesterday and noticed the same thing. While overall I found it to be really fast, in some areas (like switching between home screens) it was noticeably choppy compared to my Hero. Though I should note that my Hero is rooted and running Fresh 2.1.1.
One suggestion I might make is to not use overly aggressive settings with a task killer. This has been known to cause some odd behavior with Android including choppiness.

Working amazingly for me. As close to the smoothness of an iPhone as I've ever seen.
Have you tried a full restore? Keep checking after each app installation to figure out what (if anything) is causing the problem.

Do you have Live Wallpaper running?

I do not. In fact while "conditioning" my battery, brightness down minimum, WiFi/GPS/4G/Bluetooth all off as well.

How much free memory do you have?

I noticed the choppiness too but it wasn't too bad, just unfitting of a phone with such high specs.

It's because of the Live Wallpapers, some are more processor intensive than others so some it's more noticeable on than others. Put a regular Wallpaper up and everythings nice and smooth.
I don't use Live Wallpapers anymore, they were cool for awhile but after a couple months of them on my Nexus the novelty has worn off.

I notice it also even with a regular wallpaper..i mean its pretty smooth but it does lag a bit.

I notice laggy scrolling within the HTC-built applications. For example, when looking through contact information or social updates. The scrolling is really bad, and I think that just might be because of the huge amount of information the HTC apps are processing. I'm sure all the social information being pulled from every end of the Internet isn't the easiest thing for the device to do, even if it is the Evo.
Aside from that, everything else is as smooth as butter.

Still stock on mine and I haven't noticed any lag, though I use Dolphin HD and Skyfire.

I don't have Live Wallpaper running, and about 200MB of free memory.
And I don't think it's with the HTC-built applications only. I notice it in most applications. Just put an iPhone right beside it and scroll around on both... huge difference.
I just changed the settings on Advanced Task Killer to Aggressive (down from Crazy) and Every half hour (down from When screen off). Maybe this will help... we'll see. Maybe Advanced Task Killer is not the best app for this? Are there any better ones? Why didn't Google have this built in if it really helped so much with speed+battery life?
Maybe FroYo will fix this issue? Does anyone know when this will be available?

I have noticed this too at times. Froyo made my Nexus One a hell of a lot faster, it will do the same for the Evo

Still on Stock rom and no root, scrolling, pinch zoom are all smooth and fast.

First u have to realize that the iphone was built with its gpu base OS. So all the scrolling and animation are base on gpu WITH THE HELP OF CPU. Android will be more dificult since of all its different hardware. Iphone OS is just base on iphone hardware but If iphone was running without gpu support, it would move like crap.
One example of this is zuneHD. it is base on a hardware base on tegra with gpu support and is smoother than iphone since tegra is a more capable gpu chip.
This discussion has been on and off with palmpre guys and waiting for an update to enable gpu support in the OS. Gpu support is supported in game but not in the OS for scrolling etc. Just like android.
This is the reason the iphone can run smooth at low mhz. The iphone 2g even at its low mhz still is smoother in scrolling and transiction than android because of it gpu intigrationbut ofcourse not faster. Hope this help.
Another example is compiz for linux. It create a semi gpu OS of linux and u can see how compiz on linux look light yeat better and smoother than wimdows 7 with a much lower hardware spec.

Thanks that explains a lot, i wasn't aware Android doesn't use GPU support in this area.

I just wanted to throw this in. I know everyone is comparing things like the scrolling framerate to the iPhone's. But there is one slight issue that a lot of developers can tell you off the bat.
JAVA
iPhone is not based on java and android UI is. This is sort of why JIT is slated to make such a big difference. Java is just laggy, especially when it comes to UI. For instance: open office, eclipse, and just about any other java based app I see on linux. GTK apps are fine in ubuntu, but when I open eclipse I just know there is a delay between when I click the "file" menu and when it actually opens.
I noticed it on my hero, and no amount of free ram or killing apps would completely get rid of it. Now I have to say going from the hero to the evo I honestly do not notice any lag. But the UI on the hero just has a solid delay EVERYWHERE you go. But I noticed it was not there as soon as I got into a game written in the dalvik way. It will come, and we will eventually be there. But I don't blame it on hardware. Core2quad in eclipse and the UI lags? Blame it on Java.
Now I know some folks will say "nu uhh. such and such java android app doesn't do that!" But almost all apps for android and sense do this if they are written in java. Some more than others.
One final thing, there are several articles about why you shouldn't use task killers. It became perfectly clear it was a bad idea on some of toast's later kernel. and yes, the memory management can be improved for root users. but for non root users, I know it is counter-intuitive but task killers have major drawbacks. Just do some searching and decide for yourself, but I noticed a huge difference on my hero when I stopped using a task killer and allowed the default memory management to take over. And honestly, on my EVO I don't EVER notice a slow down.

4.2 Update- MAJOR Gaming Performance Increase

After updating to 4.2 via using the toolkit to download and flash google 4.1.1 factory image, then updating to 4.1.2 via OTA, then flashing the 4.2 update via recovery, I have noticed something very special...
Gaming. Oh my god. Gaming. What happened? What the hell happened? I mean- one minute I was happily running 4.1.2, the latest Smooth Rom, coupled with Motley a11, with the GPU clocked at 520Mhz, and the CPU at 1.6Ghz. And playing games.such as NFS Most Wanted and NOVA 3 was... Acceptable. Just about smooth enough to enjoy (20-25 FPS). And the next minute, I'm running 4.2 stock, with 100% stock frequencies for every aspect of the tablet, and gaming is soooooo darn smooth!!! (30-40 FPS). I mean- what the actual hell have Google pulled here??
Before its mentioned- I've checked. Both of the games mentioned still have the full Tegra Effects enabled, just as they were when they were running under 4.1.2.
My verdict is that when the games were running under 4.1.2, they weren't running on all cores available. Maybe just two, or perhaps even just one! Is it possible that Google have now enabled all the cores available to applications? If so- why wasn't it like this before?
What are your thoughts people?

Overclocking GPUS and CPUs doesn't always mean you're getting the best performance out of your device.. In a lot of cases it can actually cause no performance increase or worse performance.
Especially at a OC of 1.6 and a GPU at 520.. I can almost guarantee your device was getting throttled down for thermal protection while gaming..

I hope you are right. But i don't see why it would not have used all cores before, it depends more on the application using threads properly.
Will definitely try some games when i get home, wish we had a Nexus 7 at work but they preferred an iPad mini for 7-8 inches app testing

lol edit srry

Yeah you're probably right. But even on stock kernel, I wasn't getting the smoothness I am now

Nvidia recently made some improvements to their Linux driver, claiming "double the performance."
Maybe some of those improvements made it into the Tegra 3 driver for Android?
I have not tried any games on 4.2 yet, can anyone confirm what the OP said?

Yeah I am aware that over-clocking rarely means performance increase. Its just fun to experiment sometimes and see for yourself

It's slightly faster with some games, but I wouldn't call it major or anything.

Oh dear, if you call 30-40 FPS a major increase then i worry about android gaming. Its 2012. 60 FPS should be the standard frame rate by now. games should be as smooth as project butter. This is why i jumped ship from windows phone to the galaxy s3. i wanted more power to run these games properly. sadly, a lot of them dont. I bought need for speed most wanted and hope it would run at 60 fps. it dosnt unless there is something wrong with my S3. Why do android owners think that 30 fps is acceptable in this day and age of dual and quad core processors?

I can't tell you how many fps Need For Speed has on the S3 but I'd say it runs damn fast. A lot faster than on my N7 (still 4.1.2).
60 fps or 30 fps boils down to less detailed graphics or more detailed graphics on the same hardware. If you ask me, I take more details @30 fps then cheesy graphics @60 fps.

each to their own, perhaps your attitude is why developers cant be bothered to make or optimise android games to their full potential. should my quad core S3 be running games as smoothly as the same game on the dual core iphone 5? yep. do they? nope. im pretty sure that the S3 is capable. poor optimization i suspect. as an example, i bet need for speed most wanted is smoother on iphone5 than the S3 version? likely running at 60 fps but with the same graphics, same with Nova 3? FIFA 12? list goes on.

i wish i had 4.2...
and here i thought people could only notice about 24fps... everything is smooth for me (except for spiderman) and im still on 4.1.2...
p.s can you tell me why my n7 wont update to 4.2? it notifies me theres an update and i click reboot&install, and it, i think, starts installing but something happens, and it just reboots with 4.1... thanks in advance

thats what people keep saying but .if you have two copies of the same game one running at 24fps and the other running at 60fps and have them side by side. then you can easily tell the difference. Also JB, project Butter allows the UI to Run at 60fps, as they say, buttery smooth. if a person could not have be able to tell the difference between 24fps and 60 fps then why did they bother with project butter? there is a huge difference between the smothness of jelly bean compared to Gingerbread, or even ICS on some of the phones which cant quite handle ICS. thats why I want the games to run at 60fps...we have the technology and power with android now......

[Q] UI Smoothness of Nexus 4 vs any other phone (including sgs4)?

Hi all, i'm looking to upgrade to a nexus 4 and have heard praises for it's smoothness..
For those who have used a nexus 4 for a while, have you found any other phone smoother in ui experience?
...i can't stand things like skipped frames, stutters etc... this question especially for those playing around with the new sgs4 for comparison as it's a potential choice..

UI wise its buttery smooth, but some 3rd party apps are compete crap and will lag regardless of phone.

I am running Xylon ROM with Matrix kernel and also Nova launcher, phone is smooth as butter, very fast, zero lag.

I can almost guarantee that the GS4 won't be any smoother in day-to-day performance. I haven't found any phones which are better than the N4, and although the iPhone is obviously on par with the smoothness it makes so many compromises that you can't really compare them. The only place you'll potentially find lag is in third party apps as said above.

Stock kernel has the least lag in the UI.
Almost all custom kernels i tried do stutter regularly

To be honest, I never feel it lag on day to day usage but once it gets hot while playing games, it does throttle pretty quickly which leads to unexpected lag on the phone. But overall, as long as app is well coded, you shouldn't feel much lag.
Also like people said, flashing custom kernel will improve your performance and battery life dramatically. Running Franco with Paranoid Android and everything is buttery smooth!
I never used galaxy s 4 but I doubt that it'll be any smoother. S3 felt more laggy for me compared to Nexus 4 if that helps

UI is pure buttery smooth. They have a S4 Launcher.zip you can flash somewhere in the Themes and Apps forums. If you want to have a S4 experience just flash that. Its still smooth lol.

thank you all for your reassuring feedback, might just wait for the alleged 32gb refresh of nexus 4.....yea the throttling issue is a bummer..for those who want an in depth analysis of this nexus 4 throttling can look at this video http://www.youtube.com/watch?v=abf7nPiUUE8

All modern smart phones have thermal throttling. It's just that the nexus 4 has an extremely low threshold on the battery sensor which is set to start throttling at just 36 degrees Celsius, which in a hot environment leaves little lee way if any at all.
The lg optimus sister phone has the same CPU and battery but has a much higher set threshold regards the battery temp. No one seems sure why Google set the nexus 4 one so low; my grannies flat is hotter
.. I edited my thermald.conf to higher threshold of 44 degrees Celsius and along with a 150mv UV I have to really push my phone to get throttling.

even while gaming eg in NFS/other heavy games?.......any risk of bricking the cpu/gpu by setting throttling higher?

Increasing a little bit SHOULDN'T effect too much, but I wouldn't recommend that. There must be a reason why Google or LG decided to keep the throttle that low, and I am not going to argue about that as I'm not a huge gamer on my phone and the maximum time I played on my phone is 1.5hrs.

thats pretty cool...did you manage to circumvent fps drops in your game?

I've never really checked with games, most games I play don't tax the phone at all.
I ran antutu 4 times in a row to see if it would throttle and it didn't, that's the only real test I performed.

I haven't seen a phone smoother than nexus 4 on stock kernel. I also own an HTC one and it has a smooth ui, but my nexus 4 is a bit smoother than it.

you know what lags? texting. I dont know why. I use the stock keyboard.

My nexus 4 lags from time to time. I'm on cm10.1 with nova launcher. Home screen stutters sometimes. Opening and scrolling through the app drawer, messaging, or email stutters at times. (I have the music playing and low signal when I notice it.)
I don't know why people say it doesn't lag because, clearly, it does. The nexus 4 isn't up to, "par" with the iPhone UI. Sure, the 4.2.2 is buttery smooth, but I never seen an iPhone stutter, hiccup, or lag while my Nexus 4 occasionally will. Biggest gripe is when I open and swipe in the app drawer; The animation and picture loading lags when I scroll through it like a madman to test it and it drives me nuts, however nova launcher made it better.
Nexus 4 compared to Sense or Touchwiz, yeah, stock Android blows both out of the water in UI animations.

Touch input lag, choppy animations

Am I the only one with this phone who notices a serious amount of touch input lag? I see no problems with sensitivity, just a longer than normal delay. Especially noticeable while I'm typing. And besides that, animations are choppier than my original Moto X 2013. This phone feels like a downgrade in terms of responsiveness. I felt like I had the same problem with my Moto G3 as well. Is Motorola not caring at all about lolipop on their newest phones right now? Maybe they're saving the optimizations for Marshmallow? Still unacceptable.

Laggy for me 2

Try forcing gpu for 2d rendering. The option is found under developer options.
This significantly improved my Xperia M4 with the same Snapdragon 615.

Tried that already and doesn't seem to have any affect, unfortunately. I think the difference is the Xperia M4 only has a 720p resolution compared to the 1080p resolution of the X Play. Maybe the 615 cpu just struggles to push out that many pixels.

as from what i read is the snapdragon 615/Adreno 405 performance is more or less equal to snapdragon 600/Adreno 320 from the i9505 i had before.
the S4 has zero problems with 5.1.1 . i9505 has FHD too by the way. I think (hope) its a driver problem.
http://www.notebookcheck.net/Qualcomm-Snapdragon-615-MSM8939-SoC.117495.0.html
Overall, the Snapdragon 615 offers a performance similar to that of the older Snapdragon 600 (Krait architecture).

The Adreno 400 series has been substantially redesigned and supports DirectX 11.2 (FL 11_1) including hardware tessellation, OpenGL ES 3.1, and OpenCL 1.2. Furthermore, the performance has been significantly improved, which is now similar to the Adreno 320 and PowerVR G6200.

i have some small lag issues. i have small graphic glitches with the animation of the expanding musicplayer notification ( no matter what play i have used ) when a music app is running and i swipe down the notification bar.
i think these bugs and your multitouch bug is probably the same or have the same case, i think its a graphic unit driver problem.

I noticed things get a bit sluggish so I just disabled animations under dev tools.. problem solved and a slight battery saver too.

I wish we got a small update from Motorola to fix this for the time being instead of having to wait for marshmallow

No lag here
Had the phone for a month & smooth as. As suggested turn off animations in dev ops. I have mine set at .5 & works fine.

Scroll Stutter, sort of a fix?

I've been messing with GPU settings as I'm rooted now.
Tried a few different Governors under GPU. Some cause the phone to reboot, so be warned if your messing also!! Watching how the frequency of the GPU ramps up, and it's seems very reluctant, so I set it to Performance Governor, thinking it might kill the batttery life, but imo there has been no massive drop in SOT.
The upside is, for me scroll stutter has massively improved.
Maybe there is some underlying problem with the way Essential are using the GPU which is causing the issues?

This is the only issue i have with the device.. SOT is insane... Not sure what i would call the scrolling issue its like the text blurs as i scroll. Maybe a refresh issue.. is that what your seeing?

Performance just keeps the CPU maxed out. If you don't think this affects battery life, you haven't used it long enough. Performance is really not meant for use, it's just meant for getting good benchmarks. It's not great for your phone, would not recommend doing this.

I decided to test this out on my device on Oreo Beta. You are 100% correct! I changed the GPU Governor to performance using EX Kernel Manager, and no more touch scrolling stutters! I will test for 24 hours to see how much of a hit I take in battery life. The touch scrolling is also night and day on Lineage OS vs stock. I will test and report back. Thank you for your suggestion!!

Performance just keeps the CPU maxed out. If you don't think this affects battery life, you haven't used it long enough. Performance is really not meant for use, it's just meant for getting good benchmarks. It's not great for your phone, would not recommend doing this.

Yes I know, but I'm talking about GPU, not CPU.

Thanks, I'm keeping a eye on battery also for the next few days.
As a note, I've contacted Essential about this to see if it is of any use to their techs

Its not perfect, but does seem to a big difference.
I've also contacted Essential.
I'm using Kernel Auditor by the way.

This is the only issue i have with the device.. SOT is insane... Not sure what i would call the scrolling issue its like the text blurs as i scroll. Maybe a refresh issue.. is that what your seeing?

Scrolling has always been fairly good for me if you swipe the screen and remove your finger.
The issue appears when you scroll by running your finger up and down the screen whilst keeping constant contact.

One thing I was wondering about... the device uses LCD so maybe people think it's image ghosting as they touch scroll? I played around on a Pixel 2 XL and Moto Z Force today and my phone looks horrible next to those devices even with the GPU governor tweak.

In lineage os its awesome. No scroll stuttering at all. It drives me nuts in stock. But i would like to test it also.. Any specific settings that works best? This should be smooth af really with SD835. Now it's as laggy as Samsungphones. Blah! Hopefully Essential will fix this. Maybe this weekend i'll give stock a run again with root to test some settings. Someone should release a kernel

Try running GPU Governer as Performance.
Makes a difference for me with minimal battery life impact

Could be placebo, but I enabled Force GPU rendering in Developer Options and I haven't noticed the stutter as much as prior.

Well its definitly better with high gpu settings and interactive gouvrnour.

It's still so much better on Lineage OS. Even with the GPU governor set to performance on Oreo beta, touch scrolling is dramatically better in Lineage. Hopefully Essential can figure out something. I couldn't take it so I switched back to Lineage. Maybe once 8.1 Oreo is out I will try stock again. The performance on Lineage is what I would expect for this device.

Here's the reply to my report to Essential Support about the GPU settings and stutter.

Thank you for reaching out
We are aware of the issue with the scrolling stutter and our software team is working on some additional software improvements to address it. This is a high priority for our software team, and will be pushed out as a future software update.
I have seen some reports that setting it to Performance does reduce the stuttering, but I'm not sure what areas of the OS/hardware they are focusing on for the root cause. I appreciate your feedback and testing, and I will certainly share with our team.
I appreciate your patience. If you have any additional questions, please don't hesitate to respond to this email. Enjoy your weekend!
Sincerely,
Erich
