Laggy input with multi touch visualizer - EVO 4G General

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?

Yea I'm noticing some lag too :/ bummer

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.

As much as I'd like to believe otherwise, the same program running on my Droid is a bit more responsive.

But this is just a perceived problem running this test program, correct? I have read no negative issues regarding screen response in any of the reviews...

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.

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.

I feel the same way halorin. It's natural to voice displeasure over something important missed in an update (I would have loved 360* rotation, colored trackball, fm radio, etc) but I know your happy about the update when it does occur and a great guy to have on the forum
All progress is still progress toward perfection, no matter how small.
Thing is, they were just demoing the OS, not device specific things like the N1's trackball & whether it has working FM etc.
Very valid point, Rusty.
Yup, each device will have their own seperate updates with device exclusive things.

That quote is from the highlights web page:
http://developer.android.com/sdk/android-2.2-highlights.html
The axis problem can never be fixed 100% because the hardware doesn't report enough info to do it for all cases, but currently it is pretty bad and I think better drivers/software could get it close. I believe that Cyanogen's ROMs have had some tweaks that have greatly improved its responsiveness for some time now so perhaps the Android engineers adopted similar fixes. It will hopefully get good enough over time that you'd have to know exactly how the sensors work and deliberately try to fool the drivers in order to get it confused.
I tested a nexus one on froyo today at google i/o, some things that were absent, colored track ball, touch screen wise they didn't have any multi touch analysis program installed, but just pinching around I don't detect any notable differences, so i'm guessing no to those 2 features on nexus, at least on their current build
I was also at I/O and while I did play with a few different Nexus Ones that were loaded with FroYo, I was unable to determine if any screen fixes were applied.
I asked a few times and each time I was politely told that they could not talk about anything that was not already made public (fair enough btw).
However, pinching and zooming on maps seemed to be smoother (not sure if it just my impression or some actual change) and it seemed to respond overall to my finger movements more smoothly.
Also, some games that I demoed on a few different Nexus Ones did employ finger gestures and those games functioned flawlessly from the touch perspective.
I am not sure that translates into any real fix or just my biases, but I am putting it out here for whatever it is worth.

Did you notice if there was 360 rotation? ie could you flip it from 12 to 3 O'Clock clockwise and get it to rotate to landscape when in a rotating app like Maps?

Dorick, by any chance have you noticed wifi-n connection?
I'm almost certain from the API improvement and UI modifications listed on the Android SDK site that we have a software fix for the crazy multitouch issue.
Having said that, it means the screen won't go crazy when the paths "swap". But, it's still limited to two touchpoints and not 10 like the 3000 series screen.
A fix is a fix though. =)
Personally if the have fixed up pinch zooming somewhat and made it smoother that will cover me 99% of the way as I use the device so that will be pretty much a fix assuming we actually see it in the official N1 rom.

Jerky scrolling with finger down, smooth when released

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?
Sent from my GT-I9000 using XDA App
"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
Sent from my GT-I9000 using XDA App
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?

That's just a defective phone, and your second one is also defective. It happens... it could happen with the Evo too.
Whether I'd say someone should switch depends on what you like and dislike about both phones. Why did you buy an Epic in the first place? Have those reasons suddenly changed? Is uploading faster than 150kbps right now more important than any of the reasons why you bought the phone to begin with?
If you've decided you like the Evo better, then switch. I wouldn't switch because of a relatively minor GPS issue with an easy workaround, and I personally wouldn't switch because of this upload cap (I have yet to have it cause me a problem), although if you're a heavy uploader, then maybe... then again, it's probably going to get fixed at some point and then you might feel pretty dumb.
I bought an Epic because of the keyboard, so unless the phone was basically non-functional, there's no way I'd want to switch to an Evo. If you like the Evo better, though, then go for it. I just don't know why someone would buy an Epic in the first place if they really wanted an Evo, though.
Switching to the EVO would be even more depressing than the problems the Epic is experiencing. I mean the processor on the EVO is soooo outdated.
I'm sticking with the Epic.
lol i remember when evos snapdragon was all the rage haha
but yeah upload speeds fluctuating signal where my hero didnt have that problem yes battery life
i chose the epic because of the keyboard and its the only thing keeping me from exchanging
I'm in the same boat. Only thing that bugs me is battery life, and e-mail not updating at the specific times that I set.

now while the snapdragon may not be as fast as the hummingbird, its no slowpoke either. My nexus NEVER slowed down unless an app froze it. Other than that it flew. The main bottleneck in the snapdragon chipset is the freakin sucky adreno gpu.

The snapdragon might have been "all the rage" back in january when it was put in the nexus one... but when it was still being used when the EVO rolled, I was a little upset. Yeah, I'm mainly talking about the GPU. The hummingbird isn't that much faster than the snapdragon sans GPU... but it is a LITTLE bit. Considering iPhones have always had some sort of GPU in them, I figured android would too. It's nice that the anroid manufacturers are finally catching on.
The Epic has video codecs as well. Combined with the GPU, high definition videos are a breeze to watch without having to convert This is a Godsend for me.

I agree that Swype is wayyyy better than just typing in a touch keyboard and I'm so happy that it came with (I couldn't deal with my bf's touch keyboard so I knew I needed a physical one) but there are just some things that are better with a keyboard.
Does anyone use it? Because I was just wondering if other people found that it skips letters sometimes? Gets a little annoying when I'm typing a longer e-mail of sorts. When I had a Rant, I remember having to almost break it in before all of the keys were at the same sensitivity. (Namely just the Y key...I almost returned it, got lazy, and it just got better on its own...used to have to stop and smash it in to get it to work.) Anyone else have minor keyboard issues?
Personally I have no problems with the hardware keyboard and missing letters. I use the hardware keyboard for anything over a sentence or so. But yeah no problems for me. Maybe I just got lucky

I use it all the time, and never had it skip letters unless it was my fault for not hitting them properly. I love the keyboard but it's still not perfect for me; the letters are maybe a little too far apart, so I sometimes hit in between two letters. Can't really fault the phone for that, though; at least not the build.
It does seem like the space bar actually has two buttons under it (like it's a double length key, so it gets two standard key buttons), and I seem to hit it twice sometimes if I roll my thumb a little bit when I press it. But other than that, I have no problems with the functionality of the keyboard, I just need to get used to the key spacing. I'm coming from an HTC Fuze, which had all the letters jammed up right next to each other.

I like AOSP style text, e-mail, and speed. Gotta thank Darch for that one.
the keyboards the main reason lol

Why does the Evo have screen lag?

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.

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.

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...

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"

keyboard lag

Is anyone else getting lag when using the keyboard? It usually just happends when i am in the browser.

Most sites I go to seem fine but XDA in particular, the lag is always present. Not enough to bother me too much though.
True, I am mainly only experiancing it on xda. I might have to use their app.
I'm actually seeing this on a bunch of sites I frequent, this along with some other misc. slowdowns make me anxious for some OS updates... I cannot WAIT for CM and the crew to get going on this thing!

Do you have to do that on your PC...? Me either.
I am seeing a very annoying lag typing into forums like this (and others). 1-2 second lag - very frustrating!
Using the "about:debug" approach to disable OpenGL Rendering seems to address, but I am not clear what we lose in return.
I am also experiancing lag when typing in the browser. I think USAA and Netflix are the worst sites. I just got my xoom so I'm not sure how it was in the past with 3.0 but I think the browser still needs some work. The force closes in the browser are also annoying.

i find it worst on this site, but any site to fill in a form is crazy slow for me off and on, there seems to be no rhyme or reason. It makes editting difficult. Arrow keys would be nice. Lol
I do hve some lag on google talk but nothing like in the browser. So you're not alone
Helped reduce the lag
I disabled the Opengl rendering setting and then enabled the Normal rendering on the browser's Debug setting. Disabling the Opengl prevents the browser from properly playing the flash embedded objects though.
I have also been getting the lag on keyboard its very frustrating as its effectively reducing the productivity of a device that's designed to improve it. I am rather disgusted with Motorola for having the balls to release a device with such a fundamental flaw. I have dropped from 60 wpm to a rather disgustingly low 20 wpm! I have heard using a bluetooth keyboard negates this (can anyone confirm this) but I may aswell have purchased a laptop if I wanted a hard keyboard. I have also been having fun with the copy and paste feature when moving the cursor or actually needing to use it lol.
To fix lag follow these instructions:
Go to XDA
Scroll all the way to the bottom
Switch to XDA Classic instead of XDA 2010
Problem solved on XDA website.
As far as other forums I would imagine you could use an older version of their site.

Nice fix for xda but tbh this realy shouldnt be an issue and should have been solved before they released the device to consumers
Same issue with alot of sites. Facebook does alot also. Any real fixes, dolphin, opera etc do it also , I hate this thing

I am running a ICS rom and the keyboard doesn't lag. Not a real fix since the ICS roms are not fully functional, but it should provide hope since the ICS update should fix the lag.

this is one of my biggest issues with android ... while we get a lot of extra freedom and other stuff, iOS users dont have to deal with this crap because if something was this bad (typing from my xoom right now) I dont think apple would allow it to leave their hands. I love my xoom, I really do, but even almost a year since release, its still not as good (in terms of everything working like it should) than my mom's ipad 2.... just very frustrating to say the least

ICS is the answer. No lag. It's a beautiful thing.
Looking forward to ICS, only the fact the camera is not support stopped me from trying a ROM.
I OWNED a iPad 2, but maybe I am insane because I will never buy Apple products again and even though the Xoom is soon to be dated by the Quad Core Tablets I still find the Xoom better in almost ever way over the iPad 2.

We don't think you're insane...we know we have the best all around Android tablet currently available.
I can't wait for ICS, but still why does it not work in 3.x.x really.
