Has anyone noticed this? Wherever there's something to scroll, web pages, menus etc., the motion is sort of stuttering as long as you keep your finger on the screen. When you release your finger and "throw" the page, it goes smooth. This makes me think that it's not a graphic performance issue, but it's more like if the resolution of the capacitive touch screen was lower than the actual display. I hope I'm wrong and it's software related...
Software related, doesn't always do this.
Edit-
On second thought I am not sure, sometimes it does this really badly and other times it is completely smooth. If we didn't have full resolution touch you would notice it on a multi touch test app.

I think I have found the cause.
Cpu scaling!
Lock setcpu to 1 ghz and it is much smoother.
What is happening is the cpu speed keeps throttling and jumping back to full speed causing problems

Actually...still unsure...ideas anyone?

"Problems" with CPU speed jumping up and down? Those are not problems but a design decision (jury is still out on whether the implementation is done right) to save energy.
Of course you can crank everything up to the max and never put peripherals or the CPU to sleep, but please don't start complaining when your battery runs flat before the day is done.
They set the ramp down cpu speed timer far too short. This can be modded in a kernel anyway.
Using a multi touch test we have at minimum 600x300 touch resolution, way more then enough to have lag free scrolling.
There's an acer android phone out with only about 32x 24 touch resolution. They manage

I don't think it's related. I'm experiencing this even with the cpu locked in performance mode. On the other hand, using a multitouch test app, I was able to move a pointer pixel by pixel at what seemed to be the screen's full resolution, so touch res is not the cause.
It's quite annoying cause even if you want to launch a fast scroll of, say, your contact list, you get that initial ugly small stutter... when browsing the internet this ruins the experience even more, since you are likely to keep your fingertip on the screen more.
Dunno about you guys but uninstalling Gesture Search by Google fixed it for me.
Never had that on my phone...

Could be, I had a HTC HD2 and it suffered from that problem alot. numerous videos have been posted on youtube because of it as well.
One possible way of minimizing the problem is to electrically discharge your screen, by putting an electric conductor, such as metal on it to remove and negative/postive ions still hanging around. Read that up somewhere and it somewhat helped my HD2.
Personally i have only experienced once on my Sgs and have not been able to replicate it since.
If you have big fingers that could also be a problem as the touch sensor can't decide on where to locate your finger...
Thank you for your answer! The electrical conductor you mentioned should go somewhere to discharge though... I can't walk around with a ground wire hanging from my phone all the time Plus, I really believe it's software. I know it always goes there but... iPhones have similar technology but they always scroll smooth. maybe it's interpolation we're missing here.
Btw I have particularly small hands!
Discharging it only has to be done only when the problem seems to be worsening. just try not to place your entire thumb on it but rather use the tips of yours fingers, that way it doesnt jerk.
I have to say this problem is pretty consistent, hence not worsening (or improving) whatsoever in any circumstances. It's just not fluid, ah my Touch HD used to be, but that was because of poor GPU (driver); we know that can't possibly be the case here, and as a matter of fact, regardless of load, stuff in the background etc, it's there all the time.
But as soon as you release the fingertip, the "inertial" part of the scrolling just goes as smooth as possible.
So I'd dismiss the electrostatic explanation, it seems like it was a non-interpolated low touch resolution... except that it's not...
Hi Folks, I have noticed the same problem running eclair 2.1 with Ryan's one click lag fix applied (the lag fix did speed it up quite a bit too!). It seems to do it after coming out of 'sleep' mode i.e when I wake it up from blank 'screen saver'. After a few scrolls or taps it starts to smoothen out a bit, but still not as I would like it to be.... Just my observations and sorry I can't offer up any Solutions... Any word if 2.2 update will make things better? Also, does anyone know when the update will hit Australia?
Welcome to android world, iphone users.
The world where not everything is super-smooth.
Actually it might be related to smoothing of touch input. Btw my scrolling is quite ok, but I come from Sybian world, world of lag.

'smoothing of touch input'? could you please expand on this?
BTW - I Never owned an iFone, and don't really go for it's comunistic ways... (although some people take comfort in it! )
Hm, touchscreen sends raw data to driver (noisy, with peaks) to driver. Driver cleans and interprets them.. (unless its done in TS firmware)
I think that more cleaning and smoothing at this stage would result in smother scrolling, but not-so-precise tracking (when drawing, etc).
I'm just speculating here, because I have no real knowledge about this.
OK... Although it seems like there is a delay in reloading to short term memory when coming out of hibernation? Would this sound like a place to start looking? if so, anyone have any ideas on how to manipulate this function?

I downloaded the visualizer app (the one with the 2 dots and not the square)
and yea if I begin on the left side of the screen then touch the right and move around the points hang a bit when they cross and will hardly ever switch (unless u do complex rotating action with both points but then the switch is periodic at best)
but if I begin on the right side of the screen, the points ALWAYS switch...always...
Interesting...does that mean it's a software issue?
I already KNOW this is the wrong section but I feel this is something that could benefit from the most viewed sub forum.
edit: starting from the right side, the points fix themselves when I do the same complex rotating action that sometimes causes point switch starting from the left. I'd record it if I had a camera, but yea.
none of the 163 (at the time of this posting) viewers have anything to say?
not even a "WRONG SECTION NOOB" (Despite my non noobishness) post?
sheesh.
wrong section, noob.
wrong section noob.
hahahhaha LOVE IT.
another interesting update: The previous results were on a Cyanogen Mod...
Using Modaco Desire Alpha 14 I get the EXACT opposite results...
Starting with a finger on the left side of the screen then the right side point switch is guaranteed...whereas starting with a finger on the right then the left point switch is non-existent.
I think it is entirely a software fault...anyone who knows anything have anything to say about it?
then again, the overall finicky-ness of it is probably just a flaw period...though I think it can be fixed with a software update due to the different behavior between ROMs.
seems to switch points at random actually...on the desire ROM especially.
still wrong section noob. haha.
It has been covered by pretty much all tech blogs on the 'net already.
Some think it is a hardware bug, and others think it's software. Who knows.
I don't think it will matter for most people, although I consider it a serious flaw if it is not possible to fix it with software.
And yeah, this might be the wrong section, but it could also turn into a dev issue. "wrong section, noob" was funny the first time.
yea that's why I put it here in the first place, I shoulda added [Think Tank] and then squeezed my statements there...def belongs in General though...any Mod please move there without any Snarky comments prior.
i 'll move it but with snarky comment : use edit button when you want to replay to yourself instead of creating two posts
I just tried that Multitouch Visible Test, and it does not always switch the dots. It is a little bit strange though, because it seems like the dots are just put on the wrong intersect of the red and blue lines. If it is a hardware malfunction it is a very weird one. Some kind of random mirror function.
Maybe its a problem with the app itself and nothing with phones.... comon now, I don't have a problem with multitouch and I think that app is horrible to determine a bad phone..
No offence people, but these issues everyone brings up on this phone isn't a issue at all... the 3g issue is network not phone, the wonky screen is from the wrap around effect, the multitouch issue is retarded.....
The only valid one imo is the dust...... everything else seems irrelevant

The multitouch issue is not app based, otherwise it'd be present on the Droid as well (where it isn't, infact Droid's multitouch is damn near flawless looking at that video and having owned one) Though it's not going to be an issue for anything I and many others current use the phone for (Browsing, Maps, Gallery, anything else that uses pinch to zoom) it will become an issue and may already be for multitouch games...From what I saw it seemed like it is likely software based due to the fact that on the Cyan ROM one thing happened in one order and on the Desire ROM same thing happened (and a bit more buggy) in another order.
But yea, about the 3G issue..I never had that either...in fact my 3G with my N1 is better than the 3G i had with my G1.

I too have absolutely 0 issues with pinch to zoom and rotating, getting my fingers really close together, etc. 0 issues whatsoever.

Anyway, you have to remember this has absolutely NO importance whatsoever unless you play a lot of games.
If you don't, like me (I have a 360, so I couldn't care less), you'll never really have an issue with this.
Hey guys, I tested the evo 4g multitouch input with the multitouch visualizer yesterday and found that though it does have much better tracking than the nexus one(no crossing and stuff) it does seem to have significant input lag, I do not have it on me to take a video, but download the multitouch visualizer and try moving around, the dot lags behind your finger significantly, anyone know if this is a hardware issue or just not tuned right?

I seriously hope this is a software/work in progress issue. I'd be severely disappointed to see HTC make such a mistake that they've avoided with past phones like the Incredible. I mean, why would they make the Evo's screen worse than the Incredible's?
This might be a deal killer for me. It is one of the reasons I've avoided Android up until now.
If there is not a software patch then I am sure FROYO will remove the problems.
I have a sneaking feeling that the camera, video and lag will be addressed at the update of Froyo 2.2

The Droid has a more responsive screen and no axis-crossing issues like the Nexus One.
Personally I wouldn't have noticed the Evo's input lag if I hadn't downloaded the Multitouch Visualization Test from the Market.
wow, thats retarded, it may be a deal breaker for me.
Possible to turn off Sense UI and test again?
I would love to see a comparison side by side with the Evo & the Incredible. All of the comparison I've seen are either the Evo vs. N1 or Incredible vs. N1. None of which the two are side by side. From the comparison I've seen with Evo vs. N1, the Evo is still far superior to the N1 as far as multitouch goes. In that case I'm not to worried.
deal breaker? no lag in the UI, but lag on one program that tests multi-touch and it's a deal breaker?
at least test out actual multitouch functions, if there is lag there than maybe a deal breaker, otherwise I fail to see how this is definitely an evo problem; maybe it is a problem of the program on the phone. I'll take real use over test program for my deal breaker.

Whether or not people notice the lag while doing everyday tasks, that's a different problem. I already stated that I DON'T notice the lag doing other stuff.
But the multitouch visualization test running on both Droid and Evo shows that the Evo does indeed have some bit of input lag.
i wont call it a deal breaker but its definitely there.

+1
Is the Multi-Touch test app using OpenGL to render those dots? It may just be that the EVO is slower at rendering using the specific graphics API and nothing to do with the touch screen.
Overall it would appear that the current EVO is slightly slower than the Incredible (at least the benchmarks that I have seen on the web). I have also been reading that the firmware on the EVO is likely not the release version of software so for all we know these Google I/O and Advocate devices have been compiled in DEBUG / TEST code.
i tried this too, and it does appear to be true.
if you run the visualizer and try single-touch and double-touch response, and then go into google maps or a webpage on the browser, then try the same test, the response seems about the same. that's why i tend to believe the visualizer. i'll bet htc simply needs to optimize their touch input handling code to eliminate the lag
i also tried this killing every other running application besides the multi-touch visualizer and got the same result. it's the same whether running the htc sense launcher or the nexus one launcher. definitely not a deal breaker though
I have E-mail HTC about this and also give them my S/N of my EVO lets see what will they respond, I will let you guys know.
Thanks

Should be an interesting response, hopefully you don't get some auto-generated response based on keywords.
I agree with other posters, unless I see issues with actual use, I don't see this very specific application as anything near a deal-breaker. All other reports confirm that the UI experience is amazingly fast.
I'm not a developer, but my intuition says the observed lag compared to other devices has root in code that isn't optimized for this specific application.
Even if Froyo doesn't clear this up, it won't make a difference to me.
Its definitely not a deal breaker, but can be annoying for things like gaming and stuff.. on normal usage, you probably won't notice it.
It's most likely an input setting they put in for the phone for gesture recognition. I'm willing to bet is enough people complain about it they'll tweak it.
hi guys i have been fiddling around with 2.1 for about 24 hours now and may have found a VERY simple lag fix
on the left page there is your quick settings bar tap on the brightness tab it seems that $ony didnt optimize the screen very well on my device it is using ALOT of power witch is really no suprise but hey hopefully this may "Fix" some lag problems until the very talented devs *cough* sarcasm *cough* over at $ony actually fix the problem
cheers guys
and i just want to say thankyou to all the devs that have been working hard on the bootloader and ROOT
Wait what?
What does the screen brightness have to do with lag?
I'm guessing power consumption to much going to the screen and not enough going to the cpu / gpu that's my theory anyways
Sent from my X10i using XDA App
The two are mutually exclusive. Neither affect each other.
Also, the quick way to test this is to just turn down the brightness and see if the phone is still laggy. It probably will be.
actually, when your phone starts to lag, if you use the app android info, alot of the cpu power, is going to the face recognition operation. Like around 60-70 percent cpu power. Which is weird that you cant disable it... when it isnt doing that, the phone runs buttery smooth. It starts on its own for some reason even with all my auto-syncs off :\ its worthless anyway, all the pictures it tagged were all wrong
I noticed that the Evo has a touch sensitive lag that is more apparent than any other device. A lot of noobs here thought it was due to the FPS but obviously it wasn't. I can figure it out myself because logically, screen size does not change how heat is transfered between the screen. I'm really curious what exactly it is.... notice how on the iPhone/iPad/iTouch there is zero to no lag in touch display and movement which is what makes gaming on Apple so wicked. The Evo is by far the worst device for this.... Its not a deal breaker by any means, but it is very noticeable when switching between an Apple product and the Evo.
Anyone got any theories as to what it may be? The lag is definitely there but nobody is really talking about it. There MUST be a fix - and NO its not putting custom rom like CM6 on it... its not a rom issue.
I really hope that in future devices Android phone makers will focus on reducing lag times. If there is any apparent gap between iOS and Android besides that app market it would be the lag issue. The reason I even thought of this was when reading a gaming thread earlier today - made me curious...
Oh I totally agree! Just spent 30 mins on 1 level of angry birds trying to be precise and ugh....I'm still trying to calm down.....damn frustration. I've never really spent more than 5 mins with an apple phone so I can't compare. But I could totally tell the lag. But really I've only actually noticed it a couple of times so I dunno what's up

That's not what the OP is talking about. You're thinking of "visual smoothness", the OP is talking about touch accuracy.
Here's a article that goes into it and shows how much better the iPhone is. It's from earlier this year, so no EVO or iPhone 4 comparisons, but it should be a similar case for both.
never had any issues with screen lag/responsiveness.
On a side note though, and very weird, I went to do a test in Angry Birds like someone had mentioned and Angry Birds was mysteriously no longer installed on my phone...bizarre....
Well, guess I misunderstood the OP as well. Mine is very responsive. Sorry.

I'm using MIUI and Zen kernel and have no noticeable lag, even when playing games. I will say, however, that the glass screen of the iPhone does give it a performance boost on touchscreen response.
i had some lag issues with fresh 3.4 with the stock kernel switched to kings bfs 11 touch lag gone don't know why but it was switched to net's and lag was back left that kernel on and recalibrated the touch screen by calibrateing the keyboard and lag disapeared again but that was me don't know if it will work for anyone else

It even supports gloved hands if the OEM wants that enabled.
The only lag I have is when the phone is plugged in/charging. Other than that there is absolutely no other lag on my Evo. Those that are experiencing lag make sure it's not during charging.
On a side note the OP is truly an iPhone bias according to his previous post. Thought It's pretty funny.

If you're up-to-date and you have a significant amount of free space on your internal storage and your phone is still laggy... return it because it's obviously defective.
Try a factory reset and/or a new kernel. Then kill off some of the sprint and htc bloatware.
Going from HTC Kernel #11 to #17 there was a noticeable difference in performance for me.
Going from there to AOSP was a complete improvement.
The stock rom is unbearable once you use a tweaked rom.
If none of that works I would bet your phone is defective and you should go back to your iphone.
Want to supply us with a software version and kernel version of your phone?
Or atleast something more than "The Evo sucks and the iphone is great"
As the title mentions, touchscreen response on my A70 seems laggy or jumpy when playing AB.
Basically, when trying to do the fine adjustments to aim, the A70 wants to jump around several pixels worth of movement. (sometimes up to about 1/4 the hight of a bird) On my Nexus 1 and G-tablet I could adjust aim down to pixel sized movements.
It may be due to being close to the screens edge, but I was wondering if anyone else has noticed this. It is not a constant issue, but touchscreen response definitely seems less precise all around when playing the game. Most other apps I use do not need such fine adjustments, so I can not tell if this happens in them as well.
Edit: Downloaded a multitouch tester. (multitouch vis test) This app plots your finger with x,y cords and a visual dot. When moving slowly, both tracking methods made small jerky hops rather than following my finger smoothly. I have never had this happen with any other android device. And yes, I did try the screen calibration in settings several times.
No one else have this problem?
I have this as well... pretty annoying.

If this is common, then thats unfortunate. If it is rare then we know that we need to talk to archos support.
Are you in fw 2.0.71 ? I think is firmware related problem. I downgraded to 2.0.54 and have much fewer problems. And a faster a70 (z4root and SetCPU 1000mHz)
Hi there, first Message from me and first Touchscreen device...
i think it is because the wires of the touchscreen are not so close together.
When i look at them, the distance of them seem to compare to the "jumps" you mentioned.
But i have no other device to look at.
Are you using an App Killer before starting Angry Birds? I use the System Monitor to kill all unneeded applications to get at least 90 MB of free RAM before started Angry Birds and it runs very smoothly with excellent response from the touchscreen.
Bye.

No, but the multitouch test app is not a RAM heavy app and it also has this problem.

As the title mentions, touchscreen response on my A70 seems laggy or jumpy when playing AB.
Basically, when trying to do the fine adjustments to aim, the A70 wants to jump around several pixels worth of movement. (sometimes up to about 1/4 the hight of a bird) On my Nexus 1 and G-tablet I could adjust aim down to pixel sized movements.

please try: Settings->Repair->Touchscreen Calibration
Hi _nz_
Did you read the op last sentence.
"And yes, I did try the screen calibration in settings several times."
I have noticed this same issue on my 70.
Hmm, maybe I should start a poll. Try to get a rough guess at the ratio of those with and without this issue.
I also have this problem with my 101. Sometimes the game has frozen completely. I mean freeze as: the screen freezes but the game continues. I can hear the audio still. If I am firing off a bird it will freeze and I can hear the bird continue to fly and break things but can't do anything about it. I have to exit the game and then jump back in. Really annoying when you are at the last move to beat the level. :-( There doesn't seem to be any fix that works for me of the things I've tried. Very frustrating. Still love the unit though!
I don't see this issue on my 70. I'm not too good at ab though, maybe that's the reason.
I see the same issue on my 101. Hard to make fine adjustments.

Agreed. Kill other apps to gain more memory before playing AB. It will then plays smoothly.

This has nothing to do with the game not playing smoothly. It is about touch screen response. I have the same issue when using a 150kb multitouch visualizer app on a fresh reboot.
