Stutter in screen scrolling

Right now with all the new kenels with have manage to approach 60fps. But it will never be smooth enough if we dont get the stutter fix.
Before u begin and say that your phone does not have the stutter, well it does. The problem is at any window such has contact if u swipe u get a very smooth scrolling but if you hold your finger and scroll very slowly u will see microstutter and not a smooth scrolling.
Im not sure if this has been posted before and dont know if it might be the screen or actual Os
Im holding the zune hd & iphone. Both device does not suffer from this microstutter

Strange I have no stutter using fresh 3.2 with stock kernel.

Strange I do have stutter using fresh 3.2 with stock kernel.
And I agree with OP. I knew I wasn't the only one who noticed this. When flicking through homescreens on launcher pro (or even sense) the scrolling is completely smooth. When you hold your finger on the screen and move it, it stutters and makes very tiny jumps. It's not appealing. It's great we've been able to crack the 30fps limit despite HTC's unhelpful attitude. I think the next step would be to get rid of the stuttering.

I have the same exact issue and have noticed this from day one. It's quite annoying. I thought the fix for fps would stop it, but I was wrong. I've tried to ignore it, but such a thing cannot be ignored by my eyes. It's noticeable every time and more annoying each time.

I have been bothered by this since day one also. its the only negative thing a colleague of mine (blackberry user) has to say when he compares iphone to evo. its there wether you notice or not

When "slowly" dragging my finger to change screens I see that initial stutter but I'm not seeing the "jumping." Or is it that initial stutter?
Usually flicking through the screens as fast as my finger can go and it looks smooth as a babies .... bowel movement.

it won't be noticeable until you have an iphone or zune hd, who ever saids that it's not there is because they have not notice it at all. i have use all fresh roms and still have it.
Go to a website or to contacts and swipe to scroll, you will see a very butter smooth scrolling. Have a iphone on hand and do the same, you'll that the smoothness is about the same. Now grab the screen with your finger and slowly without let in go of the finger scroll up or down. You'll see a microstutter which is very obvious when you compare it to a OS like iphone or Zune HD (and from video do not see it in wm7). Is very annoying. I have the iphone 4g next to me and can tell you that the scrolling between home screens are about the same smoothness wise (using launcher pro with king's kenel #8). But the microstutter is so obvious between devices that is to hard not to notice.
like i said, i'm not sure if this is due to the screen or what, i'll try it on my sister nexus but is good that could take a development look into this problem aswell.

Maybe a nova/epson difference. Because my nova does not stutter.

Nova is what i have at the moment and this happens. running Evio, my friend with me right now has an epson running fresh and does it has well.

The people who claim they don't have it are simply not seeing it, but it's definitely there. It's on my brother's evo, mine, and my friends.

Honestly have to say I forgot what the sense contacts evn look like..if even different from aosp cm6...but if memory serves it is slightly and I get a smooth scroll. Went to some image heavy sites and notices that pictures sorta pixelate a bit when slowly scrolling but text bodies and links scroll smooth when inching along. Using dolphin HD over stock if that counts for anything. Like I said I see a slight stutter on homescreens initially but it scrolls smooth and as said maybe the aosp isn't giving me issues. Not sure?

i have tried CM6 and still there. It will always be smooth with any rom, even more with cm6, but this is something else. Is something with how the screen detects the scrolling touch while holding it.
like i said before, you'll not really notice it much until you see an iphone and compare both side by side. Then you'll see the problem i'm talking about.

as a previous iPhone user, this was the first thing I noticed when I got the phone. the scrolling just isn't as smooth.

build.prop edits for droid x:
To enable better scrolling speed through lists, I changed
windowsmgr.max_events_per_sec=55
to
windowsmgr.max_events_per_sec=60
Scrolling through the app drawer and contacts and any lists really is now smoother

Xoom lag issues

Anyone else have lag issues when unlocked, rooted, with oc'd kernel installed running at any speed. I mostly notice when coming out of standby mode. Text input on web pages is considerably slow, also loading of web pages. When opening apps it doesn't seem to be affected other than movie playback. Any feedback would be appreciated.....

Oh one other thing....when I first installed OC it was running like wildfire, the longer I'm running it the worse it is getting. Yes the cache was cleared, any other ideas?
Sent from my Xoom using XDA Premium App

Same issue here, not sure of any fix though.

this happens to me too but it never lastes more than a min or two.

hmmm i havent noticed this at all. have been overclocked for a little over 2 weeks with only a couple restarts due to theme installs

i mean it isn't something that is super noticable for me but sometimes my keyboard lags for a couple mins but then it gets back to normal. i mean it is expected when you have a device that still hasn't had its "official full" update lol.

This makes my Captivate feel like butter. Apple has nothing to worry about.
Its disappointing, to say the least.

Yeah, but compare this experience with stock on the Captivate (cause it's not even close to Serendipity), and that's a whole different comparison
It took a while for good, stable kernels to come out for the Captivate as well. Hopefully Google changes their mind about the source code once the rest of these tablets start coming out, and then we might get some of your fantastic meals for the Xoom too!

No kidding. Flash back to stock Eclair on the Captivate to turbo charge your Xoom.

If you are running performance mode with setcpu and have a min freq above 250, the CPU will drop to 250 when you turn screen off and not go above it.
Simple fix is to keep setcpu on "on demand", but you can also keep it on performance and manually bump the freq up by going into setcpu every time you turn the screen on.

Yea, the only time i lags for me is when i am scrolling via browser or something with a lot of texts / graphics. I would assume a dual 1Ghz would be more smooth than this.

You have something wrong then. I do not have that experience. In fact, if I try to do some intense things like video recording using your Captivate ROM, my phone chokes where my Xoom does not. Granted, the Xoom does lag for me with certain things, mostly certain web sites in the browser including this site, the overall responsiveness has been just as good or better than my Captivate with your ROM.
Perhaps you should be more specific on what you have installed, how your screens are configured, what widgets you are using, etc. so maybe the culprit can be identified. Are you full stock with nothing installed and experiencing this?

I disagree. You have a bad unit or your doing something wrong. Back off the bashing.

Yep, I think theres lag in every Android tablet I've played with. Googles min specs just aren't high enough for Honeycomb... Hopefully a bit more RAM and Quad Cores will fix it...

You know how you can install crappy software that runs at boot which will make even a core i7 with a good GPU and lots of RAM start lagging?
Yeah. Like that. Don't install lots of crap and expect the OS to handle it.

I've seen logs from users with 40+ boot services while trying to diagnose field issues with my apps.
The scary thing is I think it's more common than people who are careful about watching app behavior/installing minimal apps.
To make it worse, there's a lot of crappy software for Android. It's easy to cruft up your device.
Sometimes I almost wish for Apple's walled garden and non-multitasking app switching...

Custom rom for me such as team tiamat's latest takes away much of the lag. I also run adw ex launcher which pretty much takes away all the lag.

Hi all,
Well from day one i installed ADW EX as my launcher and only ever install apps i actually need and use as opposed to installing as many as i can because i can. So far i have yet to see any of the issues some users report and have never seen any lag, crashes or freezes maybe I've just been lucky but my Xoom has done all i wanted and more without issue so far.
Marc

I have over 100 apps on my xoom, stock 3.2 and it lags after being up for 6+ days. I think some devices need to be reset. I still had horrible keyboard lag on 3.1 after that update so I did a reset and it went away. Since the 3.2 all lag in the app drawer, home screens in different orientations, and opening of apps and menus is gone for me.

im experiencing some serious lag. Not many apps installed but plenty of lag time.

Will suggest to try custom rom. It's easy. Before that may be some maintenance could help. Wipe cash and stuff. Meanwhile was thinking to try v6 supercharged script to illuminate lagging. Is there anyone have tried?

I m in stock but i nvr experience any lag .. except long boot time

its annoying. ive also experience this on my xoom wifi and i dont even have alot of apps installed. i have to reboot the tablet atleast once a day so it doesnt lag badly.

I noticed it too. It appears to have apps just sitting in a tray. If you open it, it never really gets dumped. Multitask just isn't killing these apps when idled for hours. If I am not switching between apps after an hour why keep it up?

And how exactly is it laggy? I get almost no lag, ever, on mine. And I've had the pleasure of owning quite a few tablets: XOOM, Galaxy Tab 10.1, iPad, TouchPad, Viewsonic Gtab, and Nook Color. Out of all of them, the XOOM and Tab 10.1 were arguably the most responsive.
Prior to 3.2, GPU performance was horrible when the screen was in upside-down landscape. This resulted in horrible home screen lag. Thankfully, this has now been fixed. Portrait mode is still slow. But at 0 degrees landscape, it's fantastic.

Read up on the Android Process Lifecycle before complaining about it. App handling done in a very intelligent manner, optimizing speed and responsiveness. We have tons of memory on the device, so why not leave apps as background cached processes? Plus, as part of the process lifecycle, there's a very limited amount of resources that can be devoted to background processes that do not display an ongoing notification. It's on the order of ~5% CPU utilization.

Can someone convince me to keep my tab..

I bought this a few months back don't get me wrong its a excelebt device. But im finding it slow and anoying to the poiny i want to get rid of it, im fed up with how apps can run on there own without permission and slow the hell out of the tab and kill battery i fibd it silly how the default launcher widgets dobt fit the screen. Apps dont look good at times due to the screen resolution etc. Can someone convince me otherwise ps i do use other laubchers they just lag. Only way you get a lag free tab.is if you have no apps

Or we could send around 4 big blokes with various tablet devices to show you the error of your ways....

Overcome is good, but I prefer CyanogenMod, completely sans TouchWiz. Both are great, and you should definitely switch to one of them. You will gain a lot of performance and battery life back, for sure.

Might be a rogue app. I run the 'Fast Reboot' to dump stuff before and after a game, seems to help. The 2.3.3 update made things far smoother too.

I'm running the old gingerbread prep rom that came packaged with the overcome rom. I had such great speed from this that I didn't even bother to move onto overcome.
Apart from the occasional stutter, everything is very smooth, particularly web browsing. This prep rom is just stock ginger with root, and it's almost perfect. All of the ginger builds are largely identical so I can't see how you could have ginger and bad lag unless you have an app bogging it down.
Have you tried a factory reset and started fresh?

Use Fast Reboot
its free on the market, it made my tab run whole lot faster than it was.
ofcourse after installing Kratos and overclocking to 1.3Ghz it runs a lot better, but i still use Fast Reboot. it simulates a restart without doing one, causing all processes to close and come back up.
very nice app.
you can buy the paid one for scheduling it to run at times when memory usage is too high

My favorite so far is the Camera. I have never seen a camera take a picture so quick, even on the One X or GSIII.

Wow! I had not tried the camera!! It really is amazingly fast!!
I like how accurate the new voice search is. Google really killed siri
Btw, JB imho is not so buttery-smooth. However, after a few changes I think I'm satisfied:
-Change launcher to Nova
-Root and use something like Rom toolbox to change the I/O scheduler. This greatly affected my phone. I went from cfq to deadline and it's visibly snappier.
