Why is the scroll stutter in sensation or in Android in general? WM7 or iPhone has it smooth from their first phone release.. is it something to do with screen refresh rate? Or its more OS related? Dont tell me that your android is smooth as hell..
For example when i scroll the app drawer or the settings page, i see stutter. I admit that some places (in some ROM) its smooth but most places its not. For instance, if you pan photos, its smooth.. but you scroll settings it stutters.
From a noob perspective i am guessing iphone handles "everything" like a image.. so scrolling, zooming, panning is smooth like we do on photos.. and i guess android renders as text or something else... just my wild stupid guess..
And, is there a way to fix this? or the android OS needs to be re-written? I am upset because sensation is much higher configuration than iphone 3gs. But the stutter present in sensation (even with any ROM) is not in 3gs. So i dont beleive its hardware..
Is it the screen and the capacity touch technique used by apple? i saw one video where the iphone screen is performed almost 99% close to maximum touch accuracy and sensitivity than any other phones..
see the video below..
http://www.engadget.com/2010/03/24/moto-touchscreen-comparison-recruits-robotic-implements-for-heig/
so what do you developers think?
1) Touch screen itself
2) capacitive touch technique / code used by apple
3) screen refresh rate
4) GPU rendering
5) the way OS handles the screen and images
I cant think anything else from my noob brain.. but you developers can.. anything can be done to fix this? From OS perspective.. not like my 'contacts' scroll smooth but not the browser?!
its a matter of display, its well known fact that iFail has top notch displays, whats on the other hand, basically the only possitive fact on that thing. So yes it is Apple's screen, same goes for iPad. Btw as for WP7, i own HD7 and its even worse then old Touch Cruise

If its all about display, how come cheap replacement display units from online can achieve the same thing in iPhone?
It got a be something else...
It's because of hardware acceleration. Too lazy to explain it now
Swyped from my HTC Sensation
iPhone uses the graphics processor to handle everything, not just games/videos/flash. The whole front end (UI) uses the GPU (graphics processor) in order to make everything look smooth. In a way, this is sort of a limitation of android. Hopefully Ice Cream Sandwich fixes it (it is rumoured to).

Had to disagree. If its GPU rendering why the scroll is smooth in gallary? why not in other text related lists? Android uses GPU only in image and videos?
Im going to take a guess here but i think its to do with hardware acceleration, coding infact of the operating system like apple code all their interfaces to be bosted from the gpu, however with android i would say that not everything is coded to run with the gpu and actually id say there isn't anything but if someone could list the support for what is that would help. From what i can find only things like the internet browser and games are in sync with cpu and gpu.
Maybe it's not only related to GPU acceleration because I'm running InsertCoin 2.2.2 ROM and ADWLauncher EX. With the stock kernel that comes with IC 2.2.2 the appdrawer and pretty much everything else (with some exceptions) is "iPhone-smooth" but when I tried the Unity 7.0 kernel I saw much more stuttering.
A lot of it has to do with the fact that Android is multi-tasking, real multi-tasking that is. iOS and WP7 (I think, haven't touched it in forever cause it's complete trash) do some save-state multi-tasking crap. Should scrolling be affected by this? I don't think performance should ever be sacrificed. But I think a lot of stuttering in the Android UI comes from it thinking about so many things at once.
I think the gallery is hardware accelerated.
Some things are, some things aren't. Comparison for ya: use Opera then Use the stock browser. Opera is hardware accelerated (uses GPU for rendering). See how smooth it is? Now use the stock browser and compare.
Don't quote me on this, but I'm quite sure that is one of the biggies ICS is supposed to fix.
Somehow, I think Samsung has implemented hardware acceleration for the Browser on their Galaxy S and S II line of phones. This was first noticeable when the Galaxy S got upgraded from Eclair to Froyo: the browser was much smoother (albeit glitchier.... mind you, these don't necessarily go hand in hand, you can certainly make a hardware accelerated browser without the glitches).
I think that's as far as that goes. Try a hardware accelerated video player like diceplayer (free 14 day trial in the market). Try playing a 720p or even 1080p video with it. It'll be smooth. Now go into options and change the renderer to software. Now it won't be hardware accelerated. And it'll be a slideshow.
It seems to me more of an issue of software optimization. Try scrolling with Sense 3.0 and then compare it to a sense-less rom, completely different. And then things change again depending on which launcher you choose to use. The Sensation's hardware is completely capable of buttery-smooth scrolling, it's just a matter of time till developers iron out the small kinks in their roms.
it looks like everyone thinks GPU is the reason for ios smooth scrolling. well, do you really think the first iphone released in 2007 has a powerful GPU and used for everything ios does? the 2007 first iphone does the scrolling smooth and the 2011 sensation cannot. i strongly believe its not the hardware!!! i guess there something wrong in the basics and google let samsung and htc finding their own solutions for some of the apps they create on top of android.
something else is wrong and since the users are not greatly concerned (or expressed) about this, this is not fixed yet. I wish and hope ICS fix this issue somehow..
I have been trying to find additional information about this issue and the truth is that this is the only thread that people have actually started to talk about it. If i got this right you are refering to the periodic stutter within scrolling in android and not any asynchronous glitches. Even though many blame GPUs, non HW acc. interfaces and so on, to me its a clear cut situation of refresh rates/fps clashes. Its the same scenario of outputing a 24fps movie to 60Hz monitor where ull get the same kind of periodic stutter (something almost eliminated when u switch to 50Hz). Its got nothing to do with wether the monitor is CRT or LCD, it all comes down to refresh rate vs fps. Ive clearly seen that on my O2x where, hdmi mirroring (on a 60Hz FullHD TV) is perfectly fluent while there are some visible periodic stutters everywhere within the android enviroment, except 3D applications. And what do you know.. The O2X's display has a 72Hz refresh rate! Isnt there anywhere within the android OS where devs/users can have a go with this? Changing the ' transmiting' fps of the whole OS? Let me know what u think sundar
Hi All,
Having owned a Galaxy Nexus, and getting Jelly Bean some time ago, I was expecting a lot more from Jelly Bean on the Infinity when it came to interface fluidity. My Galaxy Nexus was a lot smoother - transitions and the notification menu especially.
But then I started to notice - in apps - the notification menu is actually very smooth, but not at the home screen. All transitions were still very slow however.
I had quite a bit of a play around and nothing seemed to improve the performance. Then I think I found something, and I want some people to sanity check me. I use Apex launcher (performance was still just as slow with the default launcher). In it's options, you can disable wallpaper completely (which you cannot do on the default launcher).
When I do this...I finally get the greatly improved fluidity I was expecting. It's not perfect, but the difference is huge.
Is anyone else able to confirm this? It seems strange. I was not using live wallpapers...just a static wallpaper. How much difference can a wallpaper make?
High resolution wallpaper can slow down performances due to pictures taking space on the RAM. Thus high definition pictures can take quite a bit of data ~10MB. Though that doesn't seem to be a lot...
Well I have tried using a smaller image, but I expect Android is up-scaling it to full resolution. The anmation was much less smooth. Once I disabled the wallpaper again, animations were smooth again.
Does anyone else use Apex, or a launcher that can disable the wallpaper to test this?
I just use a 1x1 pixel of black, pretty much "removes" the need to draw the wallpaper.

Did you notice a perceivable improvement in performance as a result of using that wallpaper? It seems likely that Android will stretch that 1x1 pixel out to fill a large canvas of black, which may not give any performance increase so I would be interested to know.
I would also like to know if I am the only one noticing this difference? Maybe no one else really cares about it except for me!
I use Apex Launcher Pro. I notice no difference whether I'm using wallpaper or not. Everything seems nice and smooth to me.
I would say you shouldn't expect to much from the Infinity. The Nexus 7, being a Nexus device, will always be faster than any other devices out there. The Infinity with it lousy flash storage and a full HD screen will never be able to catch up with the Galaxy Nexus and Nexus 7 in terms of speed and fluidity.

I somewhat agree...it is certainly pushing a lot of pixels. So my expectations have not been too high. In fact, I have really been pleasantly surprised. However - for the most part - I don't believe the I/O limitations should be affecting this tablet that much. Obviously there will be some effect...the same issues I was seeing before are still present...but I still do expect some improvement from JB.
That said...I am actually seeing it...but only with the wallpaper disabled. This is what strikes me as odd...it is just a static background image...and it feels like a bug.
Maybe I should just keep it off and wait until Key Lime Pie?
Disabling unused apps and clearing their data helps a lot. If you cannot disable see if you can "uninstall updates" first after that you should be able to. If you're rooted like me you can disable even more stuff using Titanium BU.
The difference? Everything is loaded immediately on startup (i.e. no calender widget that takes 5 sec to show). Balanced mode feels like performance mode, I can go on.

What benefit is clearing a disabled app's data? My typical method for disabling something is to "freeze" it with TiBU and skip the OS menus altogether. Is there some additional benefit I could gain by clearing the frozen app's data too?
I was one of the people having slowness issues with their device but a couple of days later i figured it out. I went into the settings - apps - running and cached apps list. My ram was down to 100MB at some points. The 1GB of ram doesnt seem to be enough but we need to make due with what we got. So i installed Autostarts and disabled all the startup apps and any other apps i dont need when i change wifi state and all that other useless stuff. Google+ would run almost every 2 seconds, Maps aswell. So i disabled those apps from running at bootup and such. Now my available RAM is at 400MB constantly and it is running crazy fast. Opening the recent apps list and clearing those apps is super fast now. Also disabled some of the animation effects that jelly bean puts in. I personally am more concerned with performance then quality.
I noticed every app has notifications turned on by default (settings/apps). I don't know if it matters but I've been turning it off on everything I don't use notifications with.

I kinda laugh when I hear that it is pushing a lot of pixels so that's why it isn't smooth.... take the iPad 3 for example higher resolution, crappier specs and crappy iOS but it runs so smooth that it makes me want to trade in my infinite for it. I will have to jailbrake it to be able to do what I like but the experience will be better.... was just playing around with my friends iPad 3 and **** did I get me tinking.....

Dude, you should seriously do some homework on Anandtech to say that the iPad 3 has crappier specs. In term of SoCs and graphic performance, the A5X chip in the iPad 3 is the most powerful SoC on a tablet right now, even the upcoming Snapdragon S4 Pro is unable to compete with it. I don't have much love for Apple, but we need to consider facts. If you consider raw computing power, Tegra 3 is even behind the iPad 2. In order to drive that many pixels on the iPad 3, Apple had to include a humongous SoC as well as much bigger battery, which explains why the iPad 3 is thicker and takes longer to charge. For your information, Tegra 3 is still stuck with single-channel memory while the rest of the industry have moved on to dual-channel memory early this year (look at Snapdragon S4, Exynos 4, OMAP 4)
As much as I dislike the current situation, there is not much of a competition going on right now with SoC. Currently, on the tablet front, Apple has the most powerful SoC on the market (A5X). On the phone side, the A6 chip is also the most powerful SoC on a phone as well. I am severely disappointed at Qualcomm and nVidia for failing behind Apple so far on this front. Not much is known about Tegra 4, but they'd better bring some Kepler to it, otherwise nVidia will become irrelevant.
I like my new Asus Transformer Infinity, but not as much as I love my Samsung Galaxy sII. It bugs me that it appears that a lot of apps are much smoother/faster in loading data on the SII than on the Infinity, while the former is a year older with a slower CPU.
Does anyone has the same experience?
And what could be the cause?
On both devices I use almost the same apps, have the same accounts installed and i use the same wifi connection. My sII still uses ICS and my infinty JB (which in my opinion is much better then before), Both unrooted.
When I run the usual benchmarks (quadrant, antutu, browsermark), I get the scores you would expect: Infinity scores clearly higher than the SII and conform the results that other users report. Internet speed tests do also give expected results,
I'm experiencing the following. A lot of apps that load some data from the web (news apps for example) show a delay of 1 or 2 seconds, while the SII often loads the data instantly. Browsing on the SII gives me a smooth experience, while browsing on the Infinity often results in a couple of seconds that the tablet is unresponsive when the page is not loaded completely.
This effect is the strongest in the Stumbleupon app, which probably has an inferior browser built-in, but my SII still loads the new pages really fast. The infinity shows a lot of unresponsiveness in Stumbleupon and it results in a lot of ANR popups.
The ANR popups are not so prevalant in other apps. This did happen a lot more with ICS. On my SII I almost never get an ANR.
I understand that the tablet needs to render for a much higher resolution and that the tablet has some issues with IO performance. But can this make such a difference? Could it be that most apps are so terribly designed for tablets, that the tablet needs a lot of CPU time to upscale, which causes unresponiveness?
Or is it just my tablet?

yes.
You are not alone. I also have a galaxy s2,and it's a lot faster than this tablet.
It is not that surprising. My Sensation also feel faster and more reliable than my Infinity, guess it is just right that the S2 is much faster. And yes, the resolution does matter a lot. Imagine running Skyrim or Crysis II a 1024x768 resolution versus at 1920x1080, the difference in frame rates will blow you away.
Yup,
Most games and apps are designed for phones not tablets.
Applications for phones driving that big 'ole 1920X1200 screen with a 12 core GPU just ain't going to respond the same as the junior sized screens at a much lower resolution.
Just wait when the apps catch on to the HD wave there will be many happy campers.
Takes time...
Asus uses a tegra and samsung uses exynos. The exynos/malli processor/GPU seems to perform much better than tegra despite that tegra is made by nvidia. on paper the GFLOPS and toals MADs produced by the Exynos is higher.
The screen also is a factor as FHD screen takes more time to push all the pixels on a 10.1 screen compared to a 4.3.
Architecture of chipset as well
Manufacture also plays a part. Their coding and software implementation to make the hardware and software work together. Samsung does better in this case. ASUS is always pushing updates.
Its not just the Infinity as this was the first thing I noticed when I got the Transformer Prime vs my S2. Does resolutions play a role? Maybe a bit more in the Infinity's case but the Prime and TF300 had resolutions that's not too far off from the Galaxy Nexus but the latter with 2 less cores sure did better than the Asus tablets.
Most of it is the cheap crappy internal memory Asus decided to use for their flagship device, some of it's the higher resolution.

My wife's apple ipad 3 with the high resolution runs smooth like a baby's butt. I could only wish my infinity ran that smooth. Since complaints aren't only coming from me now the proof is right here...this tablet was made without thinking. Basically Asus wanted a great tablet on paper to jump ahead of everyone, ON PAPER, but in reality it is a pretty bad device for such a large amount of money. Better off with a cheaper laptop with an SSD drive in it really.
Not to be funny, but my droid charge (2 years old, first samsung lte phone) is faster and smoother than tf700! Asus build a biggest giant cruise ship and forgot to plug a hole in the bottom of the ship!
As any gamer knows, higher resolution means more resources needed, which means a lower frames-per-second rate. It simply has to render more.
Your S2 has a resolution of 480 x 800, your TF700 a resolution of 1920x1280. In terms of resource difference between those two, it's pretty much the difference between running Minesweeper and running Skyrim.
Add to that the fact pretty much 99% of the apps are made for phones, and in most cases specifically the Galaxy series, and it's no surprise they run better on a small phone they're optimized for than on a large full HD tablet that most app-developers don't even consider.

The storage device is a piece of crap, there's nothing wrong with the graphics performance. Every single user experience issue with this tablet is down to data not getting read/written fast enough from/to storage. It's as simple as that.
Every application that uses "RAM" is subjective as fast as at my SGS2 (runnig CM9). But the i/o perfomance at stock ROM on my TF700 is really bad. With Browser2RAM surfing is a lot snapier but still not as snappy as at SGS2. Hopefully CM10 at TF700 works as much as possible around this storage issues.
Don't forget that the TF700T has the fastest RAM of all android devices that are on sale at the moment. But it has the slowest eMMC storage, too.
As far as the browser goes, use stock browser and if you are rooted, 1st look for app browser2ram and sideload it (and follow all instructions in thread dedicated to it), then (or for anyone else not rooted) type about:debug into browser address box, hit enter, then go to settings (three small vertcal dots in upper right hand corner of screen) and choose debug menu. Check the box next to Enable CPU Upload Pathand then close it. It speeds up the browser by a lot. I'm only using the stock browser now and I'm very satisfied with its performance.
The other suggestion I have for you that feel unhappy with the TF700's performance in general, is really consider unlocking, flashing a custom recovery (I highly recommend TWRP) and a rooted custom ROM, especially the CleanROM Ultra Light Edition v1.3. This JellyBean stock-based ROM is so fast and smooth and functional, you will wonder why you waited so long to have the device you had imagined. I kid you not. I've tried all the ROMs available for this device, and though they all have their strong points, for someone looking for a better than stock experience, where everything works, right now, this one's the best and it gets even better with each update. And this is just the beginning of wonderful development for the Infinity. This is honestly, a superb machine. We owe it to ourselves to take full advantage of it.
If you're running stock it's slow. If you optimise it it's pretty damn fast. Had mine lying next to an iPad 3 and they are on the same level. How to do it? Disable (a lot) of unneeded apps and use the right software (Firefox Aurora or the above mentioned Browser2Ram)
That's not much of a win considering the ipad 3 has a higher resolution with 2 less cpu cores and running 600mhz slower.

Yup. This. The screen is a minor thing. If the ASUS engineers had not selected subpar parts for the internal SD, this thing would have absolute bleeding edge performance on every front. As it is, it often shows signs of brilliance but also has some limitations due to the system bottleneck. Your impression of the device user experience will depend heavily on your use model (and its associated memory footprint). The vast majority of issues/discussions wrt to this device basically come down to this one thing.
Barring some very serious OS hacking (ala the effort to allow external SD to replace internal) all the TF tabs will ALWAYS be limited by memory bandwidth. It's a hardware limitation. Either you can live with it or you can't. Too bad. Now that JB is here and the OS is finally decent/stable, this tab is one bad cost cutting measure away from being the undisputed best in class device in the industry. <shrug>
I'm not browsing very frequently and when I do, they are not heavy multimedia sites, so for me, the TF's certainly a really good user experience and I love the device. Games are great now that the driver bug is fixed for example. It's slightly frustrating knowing that the tab could have been amazing on EVERY front if they had spent another fifty cents on the memory... but that's life. I'll be happy if they just continue to support/stabilize/enhance the firmware. The hardware is what it is.

Well, I understand that the gpu is better and the whole ios thing is completely optimised for browsing, so yeah, it is kind of a good comparison in terms of user experience.
This!!!
My HTC Evo 4g LTE has more consistent performance than my TF700T....
It's kind of frustrating really and the fact that my daughter's ipad is ALWAYS smooth bothers the hell out of me...
Is this the way these things are designed or do I have a lemon on my hands?
The fact that there are articles instructing people that they can buy a $30 SD card and move their /data mount to the external micro SD card tells me this is a design issue...
There's nothing more frustrating than tapping the screen and not being able to tell if you mis tapped or if the tablet is IO locked and in a 'wait' state. and it happens way too damned much.
I'm not doing anything special.... all I can say is that I'm running a lot of apps and perhaps this is the problem (I've restricted background process to 4 and disabling all animations and am now using APEX launcher to even disable all animations + the wallpaper).
Max free RAM at any time is around ~250 MB...
I want to show this thing off but everytime I pull it out it's performing like **** and cache cleaning or rebooting doen't seem to help either...
Also to add - post JB I DID perform a factory reset as well. I've installed about 130 apps.

Just curious, how does tf700 compare to other android tablets? Is it a a lot slower or less smooth? It one thing to compare it to phones. I want to know how it compares to a Samsung note 10.1.
Hello, How comes some phones are more responsive than the others even if they have weaker processors? Why is an iPhone responsiveness higher than an ordinary touchscreen phone? What is the reason of the responsiveness of a phone?
Sorry if you couldn't quite understand my poor ingrish .
There are other factors besides the processor. The amount of free RAM, how well the software was written, what operating system version, etc will all have an effect on the speed of a phone. The iPhone runs a very simple launcher as its OS, plus they have the advantage of being able to design the OS around their phone.
I don't mean how fast it opens app. I mean how fast and easy you can swipe between screens. To the iPhone it seems faster to swipe between screens than on my sensation. Why is that?
I think I know what he's talking about.
Even on my old iPhone 3G, the way you swipe between home screens and overall usage feels a lot more "smooth" (for lack of better word) on iOS devices than any Android device I've ever used before.
My uneducated guess is that Apple runs SpringBoard at 60FPS with Vsync Tribble nuffer???? haha!
iinm ram can be one of the things that can come into play with that. Ios is more simple of an operating system. It's multitasking isn't like androids either. Try to swipe screens while a certain number of apps are open, try swiping again after closing all apps.

The iPhones are actually extremely powerful phones. Not only that, but Apple is able to tailor the CPU for the OS which isnt really quite there on Android thanks to multiple devices with different specs.

Responsiveness ,depends on where the grapical calculations take place. As for WP in the GPU, as for andriod not only in GPU.
With a launcher or custom ROM, you can control quickness of swipe transitions between screens. For instance, TouchWiz on Samsung doesn't have a particularly fast default transition. I am using Apex launcher and I have specified for it to be faster (there's even a faster setting that I don't use because it was... too fast for me).
It mostly depends on the kernel from which the OS was built on. The way iOS was built, it focuses on touch gestures when completing tasks or rendering. When your finger makes contact with the screen, all of the resources focus on that touch which gives the illusion of fluidity in comparison to Android that instead splits it's resources between rendering or completing tasks and touch gestures. It's all on the Kernel level. If we're talking future then no OS will be as fast as BB10 due to QNX being a beast with unlimited potential... That's if BlackBerry implements it right.
So I have read and watched a lot about the i3 5.5, probably too much. In short it's a great in almost all aspects, save from
the performance, rendering it laggy/slow/choppy at times. Is it really that bad, or is it exaggerated, or perhaps downplayed?
I'm interested in intel of day-to-day use and how the i3 5.5 handles the OS, browsing, video and gaming.
Hopefully it's more a software issue than a hardware issue, which would make sense. Hopefully the 5.1 update will be out
soon. Are the European i3 5.5's also getting the last updates, or is it only the U.S?
Hopefully these relatively small issues will be a thing of the past soon. I am planning on leaving my Z Ultra (qualcomm 800,
adreno 330) for this device and that says a lot I think of how much faith I have in it
:good:
I have definitely experience lags here and there during day to day usage but haven't really found them annoying to the point where it is impossible to use the device.
Sure, the phone could have been fitted with a slightly more powerful GPU but overall the pros outweigh the cons. Only thing left is how commited Alcatel is with regards to software updates.
Power Users should definitely stay way. However, I have no qualms recommending this phone to anyone who is looking for big screen multimedia mobile device on a budget.
Thanks for your answer. A guy at Youtube said that after a couple of updates he received from Alcatel the phone performs much better, thus implying it is not a hardware issue, but a software one. He reported a perfectly lag free i3, with maybe once in a while a minor hiccup. Did you get any of those updates yet and if so, what is the difference in performance lag wise?
We have had only one update , that has resulted in a minor improvement in the UI response. Remember, the phone is still on 5.0.2 and that is responsible for the lag to a large extent. Plus - at the end of the day, its a 1.5 Ghz quad core with 2 GB RAM - The performance will be limited to whatever that means. If you are a power user , need a phone for an year or so, and are spending $250 for the Idol3 - you might want to see if you can score a OnePlus One 16GB for the same price. From a sheer performance perspective, it will come out ahead owing to a faster processor and more RAM . There are other drawbacks , that you should consider of course.
Thanks for your insight. The thing is that the i3 runs almost an all Vanilla Android, whereas other heavier skinned phones with the same cpu run perfectly fine, no hiccups either. Mind you, 33000 in Antutu is quite substantial and should be enough to run the i3 flawlessly. I guess you're on point by saying it's still on 5.0.2 and that is probably the main culprit. Hopefully Alcatel will tackle the issue soon, then they truly have a device they can be proud of for 100%, something the bigger brands and their "flagships" can learn from, imo. Did you see any improvement after the update?
My big issue was scroll lag that was in every browser, any page that had those menu overlays would stutter like a mofo. After the update it largely fixed it but still left stutter in ad laden pages. Once I installed Adguard my browsers became butter smooth. The Adreno 405 pushing 1080p res isn't doing well in 3D demanding games... if you need a phone for that get Zen2.
Thanks for the heads up. I just installed Adguard for the lulz on my old Samsung S3, quite nifty. I think the i3 will continue to impress and possibly get even better with coming updates.
Why on earth does your thread require I be in XDA 2015 theme to view it when none of the other threads do?
Good question. Probably because this thread is made of pure win
My guess is the idol using more of the 1ghz CPU to run a little cooler and save power, and when it is slow to switch to the 1.5ghz CPU is when we experience lag. Kind of like your using a 1ghz quad core phone. The idol has been proven to run cooler than its other 615 brothers, so it may be set to run on the slow CPU more.
It will definitely get better if they ever release 5.1.1. I'm not holding my breath.
I am already on the latest update, there is slight ( not sure if placebo ) improvement when scrolling web pages with mulitple images. Overall, I think it is fine unless you are power user.
Anymore input from users? What is your experience between before and after the update regarding to smoothness?
I found enabling gpu rendering for 2d made the phone run a lot smoother.
I was barely able to view this forum on it now I can scroll up and down and its buttery smooth (with the occasional hiccup here and there)
Changing default keyboard for Fleksy fixed all for me

Funny, I love that keyboard. Fleksy all the way, looks really clean too!
Try clearing your cache and/or doing a factory reset. Worked for me after the update slowed me down a little
no more lag since 10 06 update, this phone is finally totally great
When was it released? Is there a changelog?
there was a changelog when i got it, it's about stagefright and stuff
