Laggy/Choppy scrolling?

Hey..I'm new to the forum and the Evo. I've seen a few posts about this, but haven't really been able to find an answer.
As with the other people that typically notice this, I'm an iPhone 3GS user...I bought the Evo a few days ago and love it, for the most part. I'm used to extremely smooth performance with very little lag. I noticed that scrolling through the application drawer, or the built in messages application causes huge lag, along with other menus. It seems like the most choppy performance is as the scroll is slowing down (like, if you "flick" it). So, naturally, I rooted my phone. Oh and to be clear, I'm not talking about the touch-sensor lag.
Here is what I have done so far hoping that it would eliminate the lag:
- Obviously, I've used Advanced Task Killer and removed the Live Wallpaper. Didn't really do anything. I have about 160 MB of available memory.
- Using the stock OTA rom (rooted), I installed the netarchy-toastmod-3.7.3c kernel to remove the FPS cap on my screen. It worked. Now, my scrolling is more responsive, but still choppy.
- Froyo. I've tried a few different Froyo ROMs hoping that the claimed 250-300% speed increase would eliminate scroll glitches. It did not. I tried Ava and Cyanogen ROMs.
- I tried the netarchy-toastmod-3.7.3c Froyo kernel for the Froyo ROMs. Still...choppy...possibly a little better though. It's hard to tell without seeing it side by side.
My brother has a different Droid phone (I forget which), but it didn't have a noticeable lag like the Evo does, and I know it's specs aren't as good. Is this phone doomed to low-quality scrolling? Any other suggestions?

What you're probably noticing is a lack of refinement in the easing of the animation. The only "fix" will be to view it as more responsive.

You may want to try a different launcher. For super snappy response I have heard good things about Launcher Pro. Personally I am using CM6 RC1 with some ADW tweaks and I feel like its fluid enough for me with no choppiness.

Thanks! The ADW tweak posted made the application drawer seem a LOT better (mainly because of the horizontal scrolling). I suppose I'll either just deal with the other choppiness or take it back and wait for a different phone, like the Epic. Maybe I'm just being too picky >.<

I've had great success with CM6 nightly and LauncherPro. As smooth as you can get. I had a news widget that caused some slow downs as well so make sure a widget is not causing it.

I noticed this too.
Its almost like comparable to a computer game performance on a pc
when it goes from 60 frames per second to 20 frames per second you notice it more.
if they just made it stay at say 20fps speed then it would at least keep a reasonably smooth experience
I will try the CM nightly build see if I have any luck.
I love the evo too but man the iphone 4 seems so much smoother when in reality its probably not.
its all about the way its presented
i am currently using baked snack 1.1 with netarchy kernel
if i install cm do i have to flash a different kernel or will it automatically do it?

[Q] Galaxy Nexus UI Experience

As I've noticed that most (if not all) Android phones I've ever tried have been suffering from the "non-fluid" issue. The homescreen and apps experience might be fast but they're not fluid like ones found on iOS or Windows Phone and I'm guessing that it's because previous Android phones doesn't have the 2D gpu acceleration. ICS has added the feature and I'd like to ask those owner out there if the experience is now as fluid as iOS or WP7? watching video review doesnt help because videos are formatted into 30fps. Even GS2 doesn't appear to be fluid (aka I dont think it's running at 60fps)

The home screen and app launcher are very fluid if you have a static wallpaper. With a live wallpaper there is considerable slow down. Some wallpapers are less CPU intensive than others though.

Android's fluidity is actually due to more than just Hardware acceleration. Most Gingerbread phones come out of the box very quick (Nexus S) and really glide without any apps installed. Hardware [was] acceleration is a big problem, as you were throwing efficiency out the window in order to run on everything. Now with it HW Acceleration, the slickness of the OS has multiplied exponentially giving you an experience on par with iOS (Joshua Topolsky, The Verge)
Now, here comes the real problem, apps. Android apps have the most freedom in the developer sense, and are also the most lax on what is allowed in the market. While iOS dev kit requires a stringent agreement and agreement to an app review process before getting your license, Google's Android Market is nothing like that. If you can pony up $25 (a requirement only recently), you can publish whatever the hell you have made, no matter how ugly, useless, or inefficient it is. Google's toolbox for Devs is great, even greater in terms of options in app making, but enforces no standards or required templates. This is why iOS apps all have the same look and feel while Android's app range from great to complete ****. This makes a lot of sense though as Android started late in the game, so they needed to bring up the app numbers, no matter how many were ugly soundboards or battery hog games.
With ICS, Google is taking a step in the right direction by offering the HOLO hook for developers, which will allow apps to be "prettied up" for ICS instantly. Also, more efficient protocols have been added to keep battery life and smoothness up, such as a revised Garbage Collector (actually, I think they removed it entirely) and allowed apps to share information with each other. The Garbage Collection is what make your phone lag, as it is recycling the unused code on the apps you're running in the background. The new location hook allows apps to now constantly turn on your GPS to pull your location, as they can simply request it from other apps if they don't need the most up-to-date info or if you just recently used your location on another app. The OS should be as fast as any other on the stock level, and as soon as the Apps become ICS friendly and more efficient, Android will truly have people falling in love with it

This is particularly annoying. My last Android (Nexus One) was pretty smooth on almost all live wallpapers - certainly on the stock ones. The Galaxy Nexus lags like hell (slow juttery screen swiping) on all of them except one of them. Very, very disappointing and hope it gets fixed somehow.

Live Wallpaper
Thank you everyone, I'm now ordering one for myself and hopefully there won't be a let down on the UI experience!

Strange, I owned Nexus One too and live wallpaper (stock one) isn't running at acceptable frame rate at all....it's laggy and sluggish (i changed from iPhone 3G and that might explain why)
May be you can try changing live wallpaper on Galaxy Nexus cuz the one u'r using might not be that optimized?
PS. One more question, how u guys find the battery life?

No, they most certainly did not remove the garbage collector but they implemented a more modern algoritm for it and it now makes sure to run on a different CPU core as to not take CPU cycles from the app. A garbage collector is part of the Java platform and could never just be removed since that would result in constant memory leaks that would result in a crash as soon as you filled up all the memory.

When will the stuttering laggy UI experience be addressed?
I'm tired of all the mis-information. There's a pattern: Google is about to release a new handset, they don't show the handset scrolling in any of their ads, or if they do, it's super-imposed. A handful of 'mainstream' bloggers praise the handset calling it quick and responsive and lag free. You buy into it, buy the handset, and the basic UI is anything but CONSISTENTLY fluid and responsive.
I stupidly bought the Galaxy Nexus, really wish I hadn't. Here's just one example of the issue: I have an SMS thread with a mere 27 SMS messages between a friend and myself. When I scroll the up or down the thread, it's embarrassingly choppy (stuttery - don't know what word to use for it). It's extremely unpleasant, and completely ruins the end-user experience.
What annoys me is that Romain Guy closed Android Issue 6914, claiming that it was implemented in ICS. Now ICS is here, and the Android phone is still plagued with the stutters and non-fluidness Android is renowned for. Thankfully someone else has opened a new issue (Android Issue 20278), and hopefully this time Google will FULLY address the issue.
Understandably, it annoys some people more than others. Any user who has experienced a mobile UI that is buttery smooth and fluid (free from 'jitters' and 'stutters'), and where a page or menu sticks to your finger like a magnet when you scroll, would not be able to put up with what Samsung and Google have produced. It's what the kids today would call an 'epic fail'.

I find this to be untrue, the experience for me has been really good so far. Not perfect but its close. They have come a long way, it'll only get better.
And if you think any of the ads including apple are using true device operation in their advertising you are fooling yourself.

Its the main reason i left Android. Hoping that one day they will use GPU rendering to assist with UI fluidity. If that is present, its enough for me to cancel an order. Ive been a long time Android enthusiast, but the UI sloppiness is what has kept me from keeping an Android phone for too long.

As a fellow UI lag hater I can tell you it's still there in some places. The problem is, although the base of ICS supports and uses GPU acceleration, 3rd party apps dont yet, and even if you "force" it in the developer settings, it isn't compatible with some apps, and will sometimes cause crashes.
That said, it is ages ahead of Gingerbread, but still not as smooth and fluid as iOS and WP7; not even the GPU accelerated parts.

ICS is a big improvement over gingerbread in terms of fluidity.. but it's not on the same level as iOS and WP 7 yet.
UI lag is one of the things I always hated about Android.. and I feel better about ICS than previous versions.. but they still need to improve it if they want to be on the same level as Apple and Microsoft.

FWIW, I bought the phone having read in several reviews that the phone still suffered (albeit much less) from the usual android-lag. It now compares favorably to iOS and the windows mobile platform, just doesn't match or pass them in fluidity and smoothness.
In my experience, many aspects of the UI are "buttery-smooth" and whatever else reviewers usually say. However, there are still a good amount of moments where lag and hangups are present. The difference is, I'm ok with that. I've accepted the phone for it's plusses, despite it's minuses.
To be clear though, it does lag and hang from time to time. Rebooting once a day helps and I believe forcing GPU rendering under developer settings generally helps.

Dont forget that Andoid does much more in the background and foreground compare to iOS or WP7.
Think multitasking, customization, widgets, etc.
It is understandable Android cannot be as smooth as those iOS and WP7.
And for me, it is more than good enough. I wont ditch Android because it might lag a little bit, because the advantages are much more valuable.

Here, this just in ... a thorough explanation from Google Developer about Android graphics:
https://plus.google.com/u/0/105051985738280261832/posts/2FXDCz8x93s
I copied the text here:
How about some Android graphics true facts?
I get tired of seeing so much misinformation posted and repeated all over the place about how graphics rendering works on Android. Here is some truth:
• Android has always used some hardware accelerated drawing. Since before 1.0 all window compositing to the display has been done with hardware.
• This means that many of the animations you see have always been hardware accelerated: menus being shown, sliding the notification shade, transitions between activities, pop-ups and dialogs showing and hiding, etc.
• Android did historically use software to render the contents of each window. For example in a UI like http://www.simplemobilereview.com/wp-content/uploads/2010/12/2-home-menu.png there are four windows: the status bar, the wallpaper, the launcher on top of the wallpaper, and the menu. If one of the windows updates its contents, such as highlighting a menu item, then (prior to 3.0) software is used to draw the new contents of that window; however none of the other windows are redrawn at all, and the re-composition of the windows is done in hardware. Likewise, any movement of the windows such as the menu going up and down is all hardware rendering.
• Looking at drawing inside of a window, you don’t necessarily need to do this in hardware to achieve full 60fps rendering. This depends very much on the number of pixels in your display and the speed of your CPU. For example, Nexus S has no trouble doing 60fps rendering of all the normal stuff you see in the Android UI like scrolling lists on its 800x480 screen. The original Droid however struggled with a similar screen resolution.
• "Full" hardware accelerated drawing within a window was added in Android 3.0. The implementation in Android 4.0 is not any more full than in 3.0. Starting with 3.0, if you set the flag in your app saying that hardware accelerated drawing is allowed, then all drawing to the application’s windows will be done with the GPU. The main change in this regard in Android 4.0 is that now apps that are explicitly targeting 4.0 or higher will have acceleration enabled by default rather than having to put android:handwareAccelerated="true" in their manifest. (And the reason this isn’t just turned on for all existing applications is that some types of drawing operations can’t be supported well in hardware and it also impacts the behavior when an application asks to have a part of its UI updated. Forcing hardware accelerated drawing upon existing apps will break a significant number of them, from subtly to significantly.)
• Hardware accelerated drawing is not all full of win. For example on the PVR drivers of devices like the Nexus S and Galaxy Nexus, simply starting to use OpenGL in a process eats about 8MB of RAM. Given that our process overhead is about 2MB, this is pretty huge. That RAM takes away from other things, such as the number of background processes that can be kept running, potentially slowing down things like app switching.
• Because of the overhead of OpenGL, one may very well not want to use it for drawing. For example some of the work we are doing to make Android 4.0 run well on the Nexus S has involved turning off hardware accelerated drawing in parts of the UI so we don’t lose 8MB of RAM in the system process, another 8MB in the phone process, another 8MB in the system UI process, etc. Trust me, you won’t notice -- there is just no benefit on that device in using OpenGL to draw something like the status bar, even with fancy animations going on in there.
• Hardware accelerated drawing is not a magical silver bullet to butter-smooth UI. There are many different efforts that have been going on towards this, such as improved scheduling of foreground vs. background threads in 1.6, rewriting the input system in 2.3, strict mode, concurrent garbage collection, loaders, etc. If you want to achieve 60fps, you have 20 milliseconds to handle each frame. This is not a lot of time. Just touching the flash storage system in the thread that is running the UI can in some cases introduce a delay that puts you out of that timing window, especially if you are writing to storage.
• A recent example of the kinds of interesting things that impact UI smoothness: we noticed that ICS on Nexus S was actually less smooth when scrolling through lists than it was on Gingerbread. It turned out that the reason for this was due to subtle changes in timing, so that sometimes in ICS as the app was retrieving touch events and drawing the screen, it would go to get the next event slightly before it was ready, causing it to visibly miss a frame while tracking the finger even though it was drawing the screen at a solid 60fps.
• When people have historically compared web browser scrolling between Android and iOS, most of the differences they are seeing are not due to hardware accelerated drawing. Originally Android went a different route for its web page rendering and made different compromises: the web page is turned in to a display list, which is continually rendered to the screen, instead of using tiles. This has the benefit that scrolling and zooming never have artifacts of tiles that haven’t yet been drawn. Its downside is that as the graphics on the web page get more complicated to draw the frame rate goes down. As of Android 3.0, the browser now uses tiles, so it can maintain a consistent frame rate as you scroll or zoom, with the negative of having artifacts when newly needed tiles can’t be rendered quickly enough. The tiles themselves are rendered in software, which I believe is the case for iOS as well. (And this tile-based approach could be used prior to 3.0 without hardware accelerated drawing; as mentioned previously, the Nexus S CPU can easily draw the tiles to the window at 60fps.)
• Hardware accleration does not magically make drawing performance problems disappear. There is still a limit to how much the GPU can do. A recent interesting example of this is tablets built with Tegra 2 -- that GPU can touch every pixel of a 1024x800 screen about 2.5 times at 60fps. Now consider the Android 3.0 tablet home screen where you are switching to the all apps list: you need to draw the background (1x all pixels), then the layer of shortcuts and widgets (let’s be nice and say this is .5x all pixels), then the black background of all apps (1x all pixels), and the icons and labels of all apps (.5x all pixels). We’ve already blown our per-pixel budget, and we haven’t even composited the separate windows to the final display yet. To get 60fps animation, Android 3.0 and later use a number of tricks. A big one is that it tries to put all windows into overlays instead of having to copy them to the framebuffer with the GPU. In the case here even with that we are still over-budget, but we have another trick: because the wallpaper on Android is in a separate window, we can make this window larger than the screen to hold the entire bitmap. Now, as you scroll, the movement of the background doesn’t require any drawing, just moving its window... and because this window is in an overlay, it doesn’t even need to be composited to the screen with the GPU.
• As device screen resolution goes up, achieving a 60fps UI is closely related to GPU speed and especially the GPU’s memory bus bandwidth. In fact, if you want to get an idea of the performance of a piece of hardware, always pay close attention to the memory bus bandwidth. There are plenty of times where the CPU (especially with those wonderful NEON instructions) can go a lot faster than the memory bus.

There was some suggestion in this thread that any acceleration is currently software based only, and that the hardware acceleration has yet to be enabled.
I don't know how accurate that is, and there doesn't seem to be a definite answer in that thread.
Perhaps in the 4.1 update?

[Q] Anyone Noticed Home Screen Lag?

Forgive me if this has been posted elsewhere but I couldnt find it.
Q1. Has anyone experienced clicking the Home button from another app or from the app drawer and seeing just the wallpaper for a few moments until the home screen widgets, folder and shortcuts are redrawn?
Q2. Also, Has anyone noticed lag when scrolling between home screens if a Live Wallpaper is used? I notice some live wallpapers make scrolling worse than some others.
If this has been posted, let me know?

Yes to Q1.
Also had lock up in gallery with a spinning circle and nothing happening.

Yes to Q2. All of the live wallpapers except one cause lag. Quite disappointing.

Yes I've noticed this which is quite disappointing considering everything is meant to be GPU accelerated and butter smooth in an iPhone-esque manner, general navigation doesn't seem any different to my HD2. Hopefully software updates can overcome these issues.

It's good to know I don't have a faulty handset but its a shame that its not as smooth as the early reviews lead me to believe (although it is very smooth once in the app drawer and other places).
Does anyone know any impressive Live Wallpapers that have little or no detrimental effect on Home Screen lag? I find Koi Free quite impressive without causing much noticeable lag (but its a bit old hat now, so I'd like something different).

Yeah I find it very hard to work out how The Verge could've given it such a high score, software in particular, and called it "blazing fast".
It's good, but it doesn't feel very fast to me.

I'm very disappointed by the live wallpaper lag, i thought ICS completely diminished any lag in the OS
all the live wallpapers make the scrolling look historic except for the one: PHASE BEAM
that one is as smooth as a picture wallpaper
anyone else? hopefully its easily fixable in a future general maintenece OTA or some custom roms

if you guys are using third party wallpapers then they probably were never updated to enable the hardware exceleration.
if your using the built in, then thats totally unacceptable IMO and is very upsetting since i was looking forward to having a device that will actually be able to run LWPs.

It feels like my Sensation with a 3rd party launcher. =(
Still love the phone but this wasn't supposed to happen.

i read in the endaget review that not all live wallpapers are HW accelerated - as of right now only "Phase Beam" (the default) one is.
Which is why you should notice theres no lag on the Phase Beam Live wallpaper (at least not for me), whereas stuff like "Nexus" live wallpaper will seem to lag
This is the paragraph i read:
"Not all the live wallpapers are fully optimized (for example, Phase Beam is, but Water isn't). Developers have to add a single line of code to their apps to take advantage of 2D hardware acceleration -- you're able to enable this as the default for all apps by checking "Force GPU rendering" in the Developer Options."
So apparently its just one line of code that devs need to add in for their apps - granted, these are GOOGLE wallpapers so im not sure why they just didnt add it in themselves.
But this also adds to the Developer options of "Force 2D rendering" - although im not sure if this will help the unoptimized live wallpaper lag
just my 2cents

1. Yes
2. Yes
I also sometimes get lag when launching the app drawer.
Scrolling widgets also seems so stutter slightly as well.
Glad to know its not just my handset, but dissapointed as well. My GS2 was buttery smooth everywhere

Well, this is disappointing. It's a pretty basic part of the user experience, one that you'd think Google would spend a lot of time on. My GS1 running 2.3.4 suffers from refilling the launcher when I return to the home screen. I was hoping the SGN with ICS would end that experience. You guys running a lot of apps? Maybe there's something in common between those affected that isn't experienced by everyone. Will be watching this thread.

Noticed it straight after first boot, amount of apps has nothing to do with it, at least for me.

Anyone tried different launchers. Different launchers play a big role in Android user experience and smoothness. I don't think any custom launcher has hardware acceleration enabled yet, but it would be worth a shot.
It is also unacceptable that the default stock Live Wallpapers from Google weren't updated to utilize the hardware acceleration. HWA is the main feature of ICS that everyone was waiting for. EVERYTHING on the Galaxy Nexus should be setup for HWA. No excuses.
On a side note, all of my phones lagged a little when using LWPs. Even my fast G2x. The SGS2 had hardware acceleration enabled... so it could just be the launcher.

adw launcher FTW.

enable 2d doesnt fix it
has this been opened as an issue in the google aosp page

Hmm. This reminds me of the first time I took my Nexus S out of the box..
Just wait for some custom roms and such, google are apparantly horrible at optimizing performance.

I have a feeling that using GPU acceleration to certain wallpapers would cause the phone to become unstable or something, like how forcing GPU acceleration has been reported to cause instability. Google probably disabled it while they quietly work on the issue.

perhaps
but the one live wallpaper works WONDERFULLY

I hate to admit it, but my Nexus is a little laggy

I have a live wallpaper on, but it still shouldnt be that laggy. My sensation could handle a lot that was thrown at it without being all that laggy. Even with live wallpaper off it's a little laggy. Keyboard in landscape mode? Laggy. Swipe from one home screen to another? Laggy.
Any fix for this!? I just can't wait until CM9 now to fix all this stuff!

I don't know man. I came from a Sensation (running CyanogenMod 7) and the Nexus blows it out of the water in terms of speed and smoothness...and the Sensation was pretty ****in' fast running stock Android.

Well I still think my Nexus is better. I love it to death! But the sudden lag kind of kills it. I don't know what the deal is either.

I read some of the live wallpapers are laggy but not all of them

Hi monkey hung
I too noticed some laggyness to begin with the Live Wallpaper turned on. Sounds like your last phone was an iPhone 4?
I've been playing around with settings and have a few concepts on what might be going on:
1. First of all, under: Settings > Developer Options, there is a setting called "force GPU rendering". I haven't tried this with the Live Wallpaper on yet, but perhaps this might help the 2D UI laggyness? Let me know what you find.
2. Disable your Live Wallpaper, I did, it saved battery life and things are much snappier.
3. Close your unused apps. I know ICS is meant to deal with old apps much better now, however, I find my Galaxy Nexus to be snappier when I close down the 30 odd applications I have left in a suspended state. It doesn't take long to swipe them off from the home screen using the right "Application" touch button down the right hand corner of the screen.
4. I've noticed that dragging my finger along the screen does not give the same smooth/matte feeling of the iPhone 4. As a matter of fact, it almost jitters/vibrates across the contour glass. If I touch with a less contact force, I tend to find the performance of touch screen to be smooth, rather when I apply more force it tends to jump across the surface of the screen creating a jagged touch slide. I've also noticed the higher sensitivity of the accelerometer. If you have a very steady hand you can see the extra performance, if you hand is un-steady, it almost looks worse than the previous phone, but in reality, it was simply my inability to hold the device in one spot that gave the poor performance, really this a reflection on how responsive the phone is to my dodgy movements.

Thanks but I had HTC Sensation with CM7. I think you must have mistaken when I made topic about my girl friend having an iPhone 4 haha

please don't go around suggesting people to do this. They are developer options for a reason.
Force GPU Rendering is only likely to introduce bugs as some apps don't handle it well. Wait for the developers themselves to enable GPU rendering. In addition, GPU rendering adds extra memory overhead to the app (8MB vs 2MB).
By suggesting this, you only end up with people who post back at the forum complaining that App X or App Y no longer works.

This doesn't "close" anything. It just removed the application from your app switching list. FYI.

Also, the switching between 3G and 4G is intentional. 3G uses less battery... it kicks over to 4G when you're actually using the data connection.
My galaxy nexus is almost perfectly responsive. It lags on occasion, but I find it to be much smoother and more responsive overall than just about any other android device I've used. (including the galaxy S II)

Im running an Unlocked version on tmobile. Its very laggy. It takes 2 seconds for screen to rotate to landscape and back, and overall its just slow. Even the data keeps fading from hspa to 3g Im beginning to fall in love with its for its beauty but performance wise my galaxy s2 was way faster and smoother. Is an update going to address this? Any input would be appreciated.

If your phone is laggy, then it's probably something on it you're running that isn't optimized for ICS. My phone runs just fine and easily outclasses any other phone I've used (and I've used pretty much every high end gsm phone that has come out here in the states). FYI your data isn't "fading from hspa to 3g", the phone idles on UMTS and when it's transmitting data it goes to hspa. This is very normal. Do a search on it if you want to know more.

please don't go around suggesting people to do this. They are developer options for a reason.
Force GPU Rendering is only likely to introduce bugs as some apps don't handle it well. Wait for the developers themselves to enable GPU rendering. In addition, GPU rendering adds extra memory overhead to the app (8MB vs 2MB).

Wow, we are really going to miss that 6 MB with the 1 GB available to the GN. My last phone was an Xperia X10 with only 384 MB of RAM, yes it was chuggy, but comparatively this amount of allocation is small and the feature seems to work well thsu far. I hardly think they are going to miss it, but your point on the Development Settings is valid to a certain degree.

I would rebut this by saying that most of my paid apps either don't work at all or don't work correctly due to the fact I'm running Ice Cream Sandwich prior to turning this option on on my own phone. There are many other reasons that apps are going to fail, particularly on Android. In retrospect, a disclaimer to this effect might have been appropriate considering the ramifications of the advice, and I direct this at hung monkey:
If you are not smart enough to draw the correlation between enabling the 2D acceleration and most of your apps suddenly not working, then you should probably not turn it on.
I have turned it on, it fixed the laggyness of the default Live Wallpaper, I haven't tested how much it saps the battery yet. Turning it on has only resulted in an improvement to my phone thus far.

From what I read about your "laggy" screen rotate. That is intended so it doesn't accidentally change orientations.

This doesn't "close" anything. It just removed the application from your app switching list. FYI.

Don't be so sure that it doesn't. For example, if I load a relatively heavy game in to memory, such as Pocket Legends or NFS Shift, and I multitask, the app is suspended. I can use the app selection menu to resume that app, and quite quickly I might ad, much faster than the time it takes for the game to load in memory.
If I then kill it with the Task Switcher, it then has to load from the start, like the suspended session was terminated when I removed it from this list. Even Google themselves said that if you like to manage your apps, then this is how you can end them, but ICS will do a good job of managing it for you anyway, the controls are there if you want them.
This behavior does not match your allegation, would you please care to shed some light?
Cheers!

I concur with the Op - the phone by comparison with my Samsung Galaxy S2, it does seem a bit laggy when scrolling between screens - I have everything setup exactly the same way as on the SGS2.
I'm not technical but I can only hope that these reasons of laggyness come down to the apps,etc. haven't been optimised for ICS yet?
When scrolling up and down the twitter, facebook or google reader apps, it just isnt as smooth as the Galaxy S2 or even the Galaxy S1.
Otherwise, very beautiful UI.

Live wallpapers need to die a horrible death. Worst Android feature ever.
To the OP, use a normal wallpaper instead and you'll see an improvement in the overall speed of the UI.

I agree! This phone lags really bad with all the live wallpapers except for the Phase Beam one. TURN THEM OFF and its by far the smoothest phone.....lol

I use wp clock and havent noticed any lag versus having it off....

Browsing. Why can't it be smooth?

So i have a top of the line tablet with octacore, 3gb of ram and the latest KitKat 4.4.2, I don't use energy saving either. And no matter what browser I use the experience is never satisfactory.
Chrome is pretty good but it has 0 functionality. We use our fingers not a mouse! And still laggy in certain situations (same goes for Samsung stock browser).
UC browser HD is very good too in terms of scrolling, but when you're typing text is lagging behind and switching and creating tabs stutters horribly.
And Firefox, the mother of lag. When you scroll down a page really fast it takes the browser up to 5 seconds to render the damn page! While you are already looking at it. Try it out for yourself, you scroll then you only get a gray page, then everything plops in very blurry and then after another few seconds stuff gets rendered and is finally sharp.
I know that every browser has this issue to some extent. But most render much faster than firefox so it doesn't appear as an issue. Anyway can't android keep a Web page in memory completely? I have 3gb of it!
Or maybe I'm doing it wrong or you guys can suggest me a different browser with good usability and smoothness? Thx in advance

Unfortunately it's not smooth and it seems that it will never be. Only next browser seems to be little better from others.

Maybe you should try Dolphin Browser, imo its quite smooth and not laggy...

Then maybe we just have different perceptions boat browser is not smooth at all on my tablet... Maybe I have to do a video or something because boat browser is one of the most laggy browsers I've tried :/ not as bad as firefox but pretty annoying.

nearly all browsers are laggy, there is so much ad crap loaded these days.
Once the page has loaded mine is smooth, so depends on you internet speed I guess.
My Ipad is the same.

Many ram doesn't mean will smooth. Because it use power of GPU and app can be use it and resoluiton.
Opera i see very smooth. Chrome and fire fox lag like hell.

We must... I've tried just about every browser on my P600.... Boat is about as fast as they come... ( I have recently started to use Habit a little more due to lower CPU use, and a few nice features).
Boat both Tablet and Phone versions have been used daily for 6months, it simply doesn't lag... I can pinch to zoom, pan, scroll all completely with ease and without any lag, stutter or hiccup. Even browsers like Opera were too slow for me, I could see the text blur for a second before becoming sharp when zooming, panning or scrolling quickly. I don't have any such issues with Boat. Others like Chrome and Firefox just aren't even close.
I have of course optimized my tablet in numerous ways (without root) such as developer option animations, and Nova launcher etc.
Feel free to try other browsers mentioned here:

If you are receiving lag on boat, you are doing something wrong or you have a problem with your tablet...

Thx for your lengthy post. I'd like to believe then, that I have different settings or something... I tried to make a video and compare boat browser and UC HD (which is smooth but has other issues).
I used n4g.com and Watson.ch both are big pages with lots of images. It's not that apparent in the video though because it's not 60fps (duh) but I think you can see the difference

Oh well ..
On an IPAD , you cant really scroll completely like you can in Android ...
On Android the faster you move your finger the sooner it reaches the bottom of the page .. But on IPAD it only scrolls to an extent , hiding the fact that its still loading the rest of the webpage in the background . IOS is really good at hiding a lot of other things too and I actually like that and dont mind that since the experience is nice .. The only reason why I dont like IOS is because of a lack of a file browser , no usb pen drive connectivity , expandable storage , and itunes for doing anything and very little customization ..
The UI on an IPAD is really smooth and thats how its been ... plus ios talks in low level language ( Objective - C ) to the hardware directly where as Android has a middle man ( JAVA ) in between itself and the hardware
I have a surface pro .. and thats really really smooth for anything but its too heavy ..
So I have realized there is no happy place yet
Ideally I would wish there will be an os that has Flexibility of Android , Smoothness and optimization like IOS and Power of The Surface pro .. with Accurate Stylus support .... Oh well I can only dream .. but its funny that such technology still does not exist in 2014 .

No happy place :crying: wurde
:laugh:
We have some amazing browsers out there... It would just be nice if they were a bit smoother overall. And somehow it feels like it's simple a matter of better code and not hardware limitations... That's what's bugging me!

No problems... I can see the differences in your video, I'm not sure it's a huge difference but I can notice it.
Can you try the Mobile version of Boat instead of the Tablet version, for some reason I mainly stuck with the Phone version, although I have both loaded. I will try and also post a video at some stage of the varying browsers on mine to also show the difference, but it may take a few days...
Also UC browser (which has a reputation for being one of the fastest) seems to work fairly well on your video. What were/are your other issues, perhaps it's easier to address those issues than trying to get the other browsers working as fast for you.

Do you use developer options?
Boat browser was stuttering for me a lot also. Seeing this thread reminded me of the force GPU rendering option which I had checked.
I just unchecked it and it seems to be making a difference
Edit: Disregard that, doesn't make any difference.

Hmm. I like the stock browser in 4.4. It's a hell of a lot faster than 4.3 was. XDA and the WSJ are heavy sites; is this slow?

To me that does seem a tad bit on the slow side. Not so much the page loading but the repressiveness to pinch-to-zoom and finger scrolling seemed a bit laggy.

Screen painting is a bit slower than my N3 but that's to be expected considering the enormous difference in display area. Page loading (which is slower than screen painting) is exactly the same on both. So is navigating around a page once it's loaded. I guess I have low standards.

I don't have a Note 3 but I have a Nexus 5 and it's no where near that laggy. In fact I'm pretty sure my Note 10.1 2014 is smoother than that as well. But I'm rooted with a bunch of tweaks, custom ROM, and custom kernel.

Here my takes:
1) Boat browser - fastest and best features, support flash
2) dolphin browser - second place, similar features as Boat, support flash
3) Others that support flash.
