Why does the Evo have screen lag? - EVO 4G General

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

Well of course you're right...
Though I have seen the lag disappear with the addition of Kingx BFS11 kernel. So technically it's not a rom, but a kernel has fixed it for me.

Really? So it does not matter how fast you move left to right the screen stays perfectly in sync with the origin....?

Well, my EVO is pretty responsive, scrolling and pressing things is super responsive.
Kinda weird, but I open the App menu and just scroll through the apps list up and down, kinda weird but it's just fascinates me sometimes .
Maybe you have too much processes going on?
I'm using EvIo Caulkin ROM

Yeah, this problem was a big letdown for me... like you said, not a deal breaker, but very annoying. It just seems to be tiny things that they overlooked. But it appears not so tiny when a lot of other people notice the issue as well.

Weird. I'm using 100% stock Evo and I also have used an iPhone extensively, and I don't notice any difference to be totally honest... the complete opposite in fact. I've always concluded the Evo was one of the best.
I'm just an average user, maybe I'm not trained enough to notice lol.

I only notice it with Sense UI... Other phones like the Epic or whatever, seem to have less of a lag with touch. The minute I install an AOSP ROM, it's butter smooth and more responsive.
And it's not a ROM issue, just a Sense issue.

DC 3.6 and net's 4.2.1 bfs. Responsive as hell. Though, before the fps fixes, lag and studder were very apparent.

The iPhone's touch panel is just better.

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"

Laggy input with multi touch visualizer

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.

Is stuttering while scrolling through lists normal for android phones?

I'm new to android phones. In fact, other than reading about them, my only experience with them is playing with the evo 4g for about 10 minutes. I was surprised at the significant stuttering while trying to scroll through lists. It made navigating the sprint tv application very very frustrating. Scrolling through the browser settings was also very annoying because of the stutter. Is this normal for android phones? Is it normal for the evo? Is there some way to fix it?
Right now I have an iphone 3g. I'm not happy with having to jailbreak my iphone just to get some basic functionality that I need. I'm afraid that with the iphone 4 won't even be able to turn on a jail broken phone without plugging it into a computer, so I really am looking for an android device, but this scrolling stutter might be a deal breaker, if it is normal.
Demo models are always torn up and not typical.
I really don't have any lag but I'm also rooted, removed the bloat and have a great task manager installed.
the nexus never stuttered. not a single step. the evo tends to. i think it has something to do with the bloatware that htc and sprint have filled it up with.
could be the 30 fps bug. the device is locked at displaying 30 frames per second so things could be choppy. that's the second thing i noticed about the phone. first was how fuzzy everything looked - i upgraded from a droid so that could be the reason.
I don't think its the 30fps bug. 30 fps would be perfectly acceptable. This is a stutter, not just slow frame rate.
If you're coming from an iPhone I can see how the scrolling would bother you. The iPhone is consistently 60fps in the UI at almost all times, does not suffer the choppiness of the Android UI when scrolling lists or applications. Restoring the 60fps target + Froyo should get the Android UI experience up to acceptable levels in my opinion.
It's the live wallpapers that make my app list stutter. I turned it off and it's smooth now.

OMGG stop blaming a 30fps cap for the phone being laggy AT ALL. Its like every single forum if someone brings something up about the phone freezing, lagging, glitching, or not working. Some random person says "its probably because the 30fps cap". Thats not going to stop things from scrolling all in one motion.
But like others have said here, its most likely just because its a demo phone and there might of been a lot of things running. Since most people dont know how to operate android devices they dont close the program and just open everything and anything. Also htc/sprint put a lot on to the phone and bog it down. The phone will be more then operational without rooting, but if you do root, you can give the phone a big increase in speed.
The 'performance improving' ROMs seem to have a great placebo effect.
The phone stutters regardless of what rom you use. The EVO 4G is a laggy phone. It is very unimpressive.
Having sprint bloatware taking up space in your phone's flash memory does not affect performance. It is not taking up ram unless it's running, and even if it is, it will get reclaimed automatically by the operating system as needed.

I'm coming from an iphone 3g which had no UI lag. Opening and closing apps took longer though. Scrolling, switching homescreens, and especially scrolling the apps list seems extremely laggy on the Evo..
Try launcher pro if you refuse to root and use the custom roms.
I have virtually zero lag and free memory is always over 200 mb
I'll agree, I just came from an iPhone 3gs and one of the first things I noticed was that the Evo wasn't as smooth. I really like the OS but the scrolling needs to be fixed.
Sent from my HTC Evo using tapatalk.
Hell... I came from an iphone 2G and it scrolls smoother than my evo.
I really think it's the refresh rate.
I had a Nexus One and never noticed the stutter, though some of my iPhone-toting friends did. But the second I updated to Froyo and everything was much faster and more responsive, I could notice how much slower scrolling and switching screens on 2.1 devices was. It's just a matter of what you're used to.
I get some stuttering when scrolling. My Hero (which I still have) doesn't do this. Strange thing is that sometimes I do not see this stuttering and it's smooth as butter. My thought is that something in the background is running and eating up CPU time.
Live wallpapers seem to make a huge difference in how smooth and regular the touch screen refreshes (like scrolling). I don't have big problems with preinstalled live wallpapers by Android and HTC, but when using most downloaded live wallpapers, the difference is noticable - for example, Galactic Core and RedEye Scanner live wallpapers make scrolling noticeably choppier.
This doesn't seem to happen as much with Nexus One I have access to. I think it might the combination of the 30fps cap and the Sense UI.
Well my plan now is to wait until the iPhone 4 is jailbroken. If the evo's stutter is fixed to the point that it is like other android phones, I'll buy the evo. Of not, I'll get the iPhone unless there's a new option on sprint or AT&T.
I should say that I don't buy that the stutter is due to the 30fps cap. I know what 30fps looks like. The scroll stutter/lag hurts useability. A smooth 30fps wouldn't.
It doesn't stutter unless your running certain live wallpapers. If you use a regular wallpaper there is no stuttering. This is not a problem with EVO as I had same problem on my Nexus but after the update to froyo everything was silky smooth even with live wallpapers. So my suggestion is if it bothers you just use a regular wallpaper until froyo drops on the EVO.

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?

'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?

HTC Incredible vs Samsung Vibrant: HTC Incredible is faster?

I have the Vibrant. My friend has the Incredible. I compared the two.
While on paper the Vibrant tops the Incredible in terms of hardware (aside from camera related areas), the Incredible seems to be a bit more snappy. Now I am not saying the Vibrant is "slow", but rather there is noticeable ~.5-1 sec delay when opening messaging, for example, where as the Incredible has none, at all. (I have applied Ryan's lagfix and hit 2.2k on Quadrant... wish Quadrant results would reflect actual performance.)
Seeing as how Vibrant has the better hardware, my guess is it must be Sense UI vs TouchWiz thing. I love TouchWiz (don't flame me) but if it is the one causing my otherwise great phone to slow down... I will nuke the thing.
What do you guys think?
I thought I saw that the incredible was starting to see froyo. Has he updated? That would make a huge difference. If you are seeing lash on the Samsung specific apps. I would say it is likely touchwiz vs. sense thing.

We need a later firmware revision. The one we have isn't very good. Later versions reduce or eliminate the type of lag you're talking about.
Besides that, I don't know what you're trying to prove here
My guess would be it's Touchwiz that causes this but there could also be other factors involved. I have a friend with an incredible and he replaced his messaging with handcent because the lag he was getting from opening the messaging app itself as well as the threads.

Have you applied the "fix" yet? I don't see any delays or lag when I open apps.
if you apply the "lag fix" i'm almost certain you won't be able to notice any slow downs in terms of opening applications.
from the limited knowledge I have of the whole "samsung vibrant lag" it's caused by the way the vibrant processes I/O read/write? it's very inefficient as compared to other phones. the fix is a work around and it literally makes it amazingly "snappy" and fast.
I'm choosing to hold off on the fix for now, people reporting issues and having to ODIN flash back to stock is turning me off.
*edit - totally missed the part that said you applied the lag fix. reading comprehension ftl

I have a friend with an incredible its a few months old but I found the opposite to be true. Using her phone made me appreciate the speed of the vibrant, I almost felt like I was back using a G1. my phone is about as stock as you can get aside from running launcher pro instead of the regular home app.
2.2 will only make this thing faster. I use touchwiz to show off my phone. It is a lil choppy but never slow. I think our only competitor when we get 2.2 will be the x but for some reason im not worried.

Me neither. Had it since release. No lag and about 120 apps installed...
Just need 2.2 and I'm golden....
Gps even works good here... lol
After spending more time with TouchWiz's launcher, I can safely say it is the root of a lot lag. Sucks because I really like it.

Frame Drops like hell

Can anyone please report if they are seeing lots of crazy frame drops on this phone? I'm running rooted Xxx No Limits, but have observed the same on Elemental OS too. When you turn on 'Profile GPU Rendering' in the Developer Settings to 'On screen bars', I see a crazy amount of frame drops every where. I bought this phone because it is suppose to offer the best smoothness and performance rivaling only the Pixel, specially after the fantastic 3T. Attached are some images showing the frame drops on even mundane tasks like scrolling Settings menu. Is anyone else seeing this behavior?
I use Action Launcher, but can anyone report if they see this on their stock launcher or other launchers?
PS: The phone 'seems' smooth and fast when doing these tasks. It doesn't seem to slow down and drop frames like crazy like an S8 or G6, which can be seen with the naked eye. It's only when I turn on GPU profiling that I can detect these frame drops. Is the GPU profiling reporting 'broken' and incorrectly reporting lots of frame drops? I'm confused.
Hey, I just checked and I got the exact same results, maybe even a bit more drops than you do. I'm using the stock launcher. Phone is absolutely smooth aside from that. I'm not sure, but this may be in correspondence with the jelly-scrolling issue? I'm not sure if I'm affected though, if yes, the jelly effect is minimal.
Are you affected by the jelly scrolling?

I don't see the jelly scrolling effect on my phone. I'm not sure if this frame drop issue and the jelly scrolling effect are related. Its interesting to know that you see a lot more frame drops in the rendering.
i agreed with you, for this phone having the latest 835 which is suppose to give a straight line of performance (no frame drops) yet i see a lot of those
what the hell is going on with this phone ...
i dont know if its the phone or the softwere but im so returning, the only reason i bought was because of the 835 and because its was the latest and will give you continues performance, its all a lie
Probably because the screen is upside down!

100%
Just tested on a Galaxy S8 and that graph looks even worst!!!!
What's happening?!?! Snap 835 is the culprit?
But I've seen a review with the HTC U11 and it doesn't do this.
Yeah mine is far from smooth as well, dunno,it just does not scroll smooth, my Nexus 5 on MIUI is soooo much smoother, way less frame drops.. I suppose theissue will vanish with the right ROM / Optmization, perhaps changing to a different CPU governor could help already..
Is this really a big deal if you can't see it until you run this log that shows you its happening?

People are like: "I didn't know I had a problem until I ran this app now I'm like O..M..G!". These people can't be for real. They should try standing on there heads, looking in a mirror, with the phone upside down.. see how it scores.

Its like the Jelly scrolling thing. I bet 85% of the people *****ing about it haven't even held a OP5. I watched those videos and then paid close attention to my 6P, guess what? It does the same damn thing!
About the only real issues I have seen are the WiFi and autobrightness issues, and camera performance. The WiFi seems to have been fixed and the camera could and most likely will be improved... I hope.
And from what I have seen out of the camera isn't bad, but it is very average for a phone bought 2 years ago. I just believe the hardware is much more capable of better results.

I'm right there with you brother.. The auto brightness has been a "real" issue for me. I have not had the jelly thing but then again I didn't go looking for it. The camera? Well I took what I though were some really nice looking photos over the 4th.

Thank god I am not the only one, reading through some of the threads I am starting to feel like I am the crazy here. People are like "The phone is smooth but this tool is showing frame drops, **** Oneplus, I am returning this phone."
So they will return a 500€ flagship which runs smooth and they dont notice lags without a tool? They expect that the CPU is the cause of frame drops?
Seriously, this must be a joke. Its just looking for a problem when you dont have one.
I do notice the jelly scrolling, but its minimal, so its kinda cool, like a subtle animation.
Camera could be better but nobody can say its bad, they just overhyped it and didn't meet expectation.
Battery life is like out of this world, I got 8h of SoT, good luck on other phones with that.
No other issues were encountered in the meantime. Perfect phone.
I get drops with the launcher, inc app drawer but it's not significant. I'm currently using a custom kernel as well.
Here's Chrome:

The screenshot you have posted doesn't show any frame drops. Can you let e know what kernel you are using?
Here are my rom and kernel details. No governor settings changes etc, I'm just using the kernel out-the-box.
