Hey..I'm new to the forum and the Evo. I've seen a few posts about this, but haven't really been able to find an answer.
As with the other people that typically notice this, I'm an iPhone 3GS user...I bought the Evo a few days ago and love it, for the most part. I'm used to extremely smooth performance with very little lag. I noticed that scrolling through the application drawer, or the built in messages application causes huge lag, along with other menus. It seems like the most choppy performance is as the scroll is slowing down (like, if you "flick" it). So, naturally, I rooted my phone. Oh and to be clear, I'm not talking about the touch-sensor lag.
Here is what I have done so far hoping that it would eliminate the lag:
- Obviously, I've used Advanced Task Killer and removed the Live Wallpaper. Didn't really do anything. I have about 160 MB of available memory.
- Using the stock OTA rom (rooted), I installed the netarchy-toastmod-3.7.3c kernel to remove the FPS cap on my screen. It worked. Now, my scrolling is more responsive, but still choppy.
- Froyo. I've tried a few different Froyo ROMs hoping that the claimed 250-300% speed increase would eliminate scroll glitches. It did not. I tried Ava and Cyanogen ROMs.
- I tried the netarchy-toastmod-3.7.3c Froyo kernel for the Froyo ROMs. Still...choppy...possibly a little better though. It's hard to tell without seeing it side by side.
My brother has a different Droid phone (I forget which), but it didn't have a noticeable lag like the Evo does, and I know it's specs aren't as good. Is this phone doomed to low-quality scrolling? Any other suggestions?
What you're probably noticing is a lack of refinement in the easing of the animation. The only "fix" will be to view it as more responsive.

You may want to try a different launcher. For super snappy response I have heard good things about Launcher Pro. Personally I am using CM6 RC1 with some ADW tweaks and I feel like its fluid enough for me with no choppiness.
Thanks! The ADW tweak posted made the application drawer seem a LOT better (mainly because of the horizontal scrolling). I suppose I'll either just deal with the other choppiness or take it back and wait for a different phone, like the Epic. Maybe I'm just being too picky >.<
I've had great success with CM6 nightly and LauncherPro. As smooth as you can get. I had a news widget that caused some slow downs as well so make sure a widget is not causing it.
I noticed this too.
Its almost like comparable to a computer game performance on a pc
when it goes from 60 frames per second to 20 frames per second you notice it more.
if they just made it stay at say 20fps speed then it would at least keep a reasonably smooth experience
I will try the CM nightly build see if I have any luck.
I love the evo too but man the iphone 4 seems so much smoother when in reality its probably not.
its all about the way its presented
i am currently using baked snack 1.1 with netarchy kernel
if i install cm do i have to flash a different kernel or will it automatically do it?
I have a live wallpaper on, but it still shouldnt be that laggy. My sensation could handle a lot that was thrown at it without being all that laggy. Even with live wallpaper off it's a little laggy. Keyboard in landscape mode? Laggy. Swipe from one home screen to another? Laggy.
Any fix for this!? I just can't wait until CM9 now to fix all this stuff!
I don't know man. I came from a Sensation (running CyanogenMod 7) and the Nexus blows it out of the water in terms of speed and smoothness...and the Sensation was pretty ****in' fast running stock Android.
Well I still think my Nexus is better. I love it to death! But the sudden lag kind of kills it. I don't know what the deal is either.
I read some of the live wallpapers are laggy but not all of them

Hi monkey hung
I too noticed some laggyness to begin with the Live Wallpaper turned on. Sounds like your last phone was an iPhone 4?
I've been playing around with settings and have a few concepts on what might be going on:
1. First of all, under: Settings > Developer Options, there is a setting called "force GPU rendering". I haven't tried this with the Live Wallpaper on yet, but perhaps this might help the 2D UI laggyness? Let me know what you find.
2. Disable your Live Wallpaper, I did, it saved battery life and things are much snappier.
3. Close your unused apps. I know ICS is meant to deal with old apps much better now, however, I find my Galaxy Nexus to be snappier when I close down the 30 odd applications I have left in a suspended state. It doesn't take long to swipe them off from the home screen using the right "Application" touch button down the right hand corner of the screen.
4. I've noticed that dragging my finger along the screen does not give the same smooth/matte feeling of the iPhone 4. As a matter of fact, it almost jitters/vibrates across the contour glass. If I touch with a less contact force, I tend to find the performance of touch screen to be smooth, rather when I apply more force it tends to jump across the surface of the screen creating a jagged touch slide. I've also noticed the higher sensitivity of the accelerometer. If you have a very steady hand you can see the extra performance, if you hand is un-steady, it almost looks worse than the previous phone, but in reality, it was simply my inability to hold the device in one spot that gave the poor performance, really this a reflection on how responsive the phone is to my dodgy movements.
Thanks but I had HTC Sensation with CM7. I think you must have mistaken when I made topic about my girl friend having an iPhone 4 haha

please don't go around suggesting people to do this. They are developer options for a reason.
Force GPU Rendering is only likely to introduce bugs as some apps don't handle it well. Wait for the developers themselves to enable GPU rendering. In addition, GPU rendering adds extra memory overhead to the app (8MB vs 2MB).
By suggesting this, you only end up with people who post back at the forum complaining that App X or App Y no longer works.

This doesn't "close" anything. It just removed the application from your app switching list. FYI.

Im running an Unlocked version on tmobile. Its very laggy. It takes 2 seconds for screen to rotate to landscape and back, and overall its just slow. Even the data keeps fading from hspa to 3g Im beginning to fall in love with its for its beauty but performance wise my galaxy s2 was way faster and smoother. Is an update going to address this? Any input would be appreciated.

The rotation delay is intentional.

I'm experiencing the same thing you are but the delay is intentional. If my screen was rotating all the time I would get really annoyed!
Also, the switching between 3G and 4G is intentional. 3G uses less battery... it kicks over to 4G when you're actually using the data connection.
My galaxy nexus is almost perfectly responsive. It lags on occasion, but I find it to be much smoother and more responsive overall than just about any other android device I've used. (including the galaxy S II)

If your phone is laggy, then it's probably something on it you're running that isn't optimized for ICS. My phone runs just fine and easily outclasses any other phone I've used (and I've used pretty much every high end gsm phone that has come out here in the states). FYI your data isn't "fading from hspa to 3g", the phone idles on UMTS and when it's transmitting data it goes to hspa. This is very normal. Do a search on it if you want to know more.

Wow, we are really going to miss that 6 MB with the 1 GB available to the GN. My last phone was an Xperia X10 with only 384 MB of RAM, yes it was chuggy, but comparatively this amount of allocation is small and the feature seems to work well thsu far. I hardly think they are going to miss it, but your point on the Development Settings is valid to a certain degree.

I would rebut this by saying that most of my paid apps either don't work at all or don't work correctly due to the fact I'm running Ice Cream Sandwich prior to turning this option on on my own phone. There are many other reasons that apps are going to fail, particularly on Android. In retrospect, a disclaimer to this effect might have been appropriate considering the ramifications of the advice, and I direct this at hung monkey:
If you are not smart enough to draw the correlation between enabling the 2D acceleration and most of your apps suddenly not working, then you should probably not turn it on.
I have turned it on, it fixed the laggyness of the default Live Wallpaper, I haven't tested how much it saps the battery yet. Turning it on has only resulted in an improvement to my phone thus far.

From what I read about your "laggy" screen rotate. That is intended so it doesn't accidentally change orientations.

Don't be so sure that it doesn't. For example, if I load a relatively heavy game in to memory, such as Pocket Legends or NFS Shift, and I multitask, the app is suspended. I can use the app selection menu to resume that app, and quite quickly I might ad, much faster than the time it takes for the game to load in memory.
If I then kill it with the Task Switcher, it then has to load from the start, like the suspended session was terminated when I removed it from this list. Even Google themselves said that if you like to manage your apps, then this is how you can end them, but ICS will do a good job of managing it for you anyway, the controls are there if you want them.
This behavior does not match your allegation, would you please care to shed some light?
Cheers!
I concur with the Op - the phone by comparison with my Samsung Galaxy S2, it does seem a bit laggy when scrolling between screens - I have everything setup exactly the same way as on the SGS2.
I'm not technical but I can only hope that these reasons of laggyness come down to the apps,etc. haven't been optimised for ICS yet?
When scrolling up and down the twitter, facebook or google reader apps, it just isnt as smooth as the Galaxy S2 or even the Galaxy S1.
Otherwise, very beautiful UI.
Live wallpapers need to die a horrible death. Worst Android feature ever.
To the OP, use a normal wallpaper instead and you'll see an improvement in the overall speed of the UI.

I agree! This phone lags really bad with all the live wallpapers except for the Phase Beam one. TURN THEM OFF and its by far the smoothest phone.....lol
I use wp clock and havent noticed any lag versus having it off....
Hello,
I´ve just bought a Galaxy Nexus and had great expectations about it being lag free. This was even my first impression but after 2 days of use I can see there are some actions that display a clear visual lag/frame drop.
- On the home screen, if I switch panels using my finger it goes great but if I press the center button to get back to the center panel the transition isn´t smooth (frame drop)
- The blue glow animations from pressing the buttons is not smooth, I can see clearly the transition from the strong glow to black again (stage by stage). It´s even stronger in the settings app, where I press any of the options (battery, app, display, ...) and it takes 1 second to open the new activity: during this time I can see 3 stages before the glow disappears.
- In the apps/widgets list, when I scroll left I can see the panel stops and quickly starts to run smooth again.
The phone came as a yakjuzs but I unlocked the bootloader and updated to yakju 4.0.2 (bootloader, radio and os).
I ran some benchmarks and got lower results than people posted on the internet:
- Quadrant: once 1419 and once 1881. Framerate on the graphics test were: 20/25 on the ladder, 7/8 on the planet and 10/20 on the dna
- Antutu: total score 6140, 2d graphics: 265, 3d graphics: 1184
Are those numbers and behaviors normal? I expected more from the device since it has 2d aceleration (activated for all the apps by the developers settings).
Any chance my upgrade to yakju 4.0.2 is the reason of this performance?
I hope you guys can help me
Gabriel Simões
ps: after upgrading I got stuck in an infinite loop so I did a factory reset and was finally able to use the phone.
(sorry for the double post on the general android forum)
Kill quadrant with fire please as it means nothing . A lot of your issues cleared up with 4.0.3.
Also don't run live walls unless they are meant for ics. That does not include all the stock ones. Phase beam and Galaxy are the only ones from Google that are ics ready. 3rd party I have no idea.
4.0.3 drastically improved my benchmarks and overall performance, went from around your scores up to 3100 with a 4.0.3 ROM and franco's nightly kernel and rid almost all lag in the UI
I specifically remember on the planet portion of the Quadrant Standard benchmark there was a whole chunk missing out of the larger planet while I was on stock 4.0.2...flashed 4.0.3 and it runs at 60 frames a second
I'm also not sure what effect ICS has on the benchmark's accuracy, if any
I'd suggest flashing a new ROM if you were planning on rooting anyway, if not hold out for the official OTA
Attached is my newest bench (franco's 13 with bixgie's 4.0.3 build 4, OC'd to 1350 on higher score and stock clocks lower score)
Its all fake.
Planets uses software rendering on sgx gpus.The renderer was removed from your rom. Its smoke and mirrors because no other apps use that like planets does. The quadrant scores arent translating to performance, and 4.0.3 on its own doesnt improve the scores. It does clear up some graphics and performance issues though.
Its nice to know I didn´t fVck my cellphone on it´s first day!
I´ve been thinking if I should upgrade to a non official 4.0.3 since I got the nexus to have a standard plataform to develop. Audio engine changed a lot from 2.2 to 4.0 and I have to update apps.
By the other side I´d like to lower voltage to improve even more my battery (I get to the end of the day with 50% left).
How is franco's 4.0.3 working for you? Is it too modded?
Also, any idea on when 4.0.3 official will come?
Last but not least, any improvements to screen quality (colors at least)?
tnx

Are there any more accurate benchmarks you'd recommend? (other than authentic usage of course) When I was looking Quadrant seemed to be the most popular (which I understand doesn't make it the best, but I figured it's a good starting point)
Also I've been using franco's nightly's since I got my phone and it's been excellent for me. Better battery life, performance, added features and patches are a nice touch too. Can't say it's too modded since I've yet to run into any issues with any of the changes he's made.

A lot of the lag in ICS is caused by the animated soft keys. This is fixed in cm9 by having the softkeys have no animation and simply just light up instead of lighting up and fading like before.

Those animatios are really instable in 4.0.2 std:
- If I open the notification bar and press home only once the animation looks great ... if I keep pressing it will lag on the 3rd or 4th time and on...
- The animation in settings menu is terrible and lags a lot ... it takes like 1 second to open the battery activity and while that I can see clearly 3 stages of animation fading out...
I'm runnin stock Nexus with Nova launcher, just noticed that there's a slight delay upon selecting a menu option.
Here's what i mean....
Say you're in the SETTINGS menu, when i select one of the sub menus e.g Sound/Display/Storage/Battery. When i click on it, it highlights it in blue while i press it, but when i let go it kind of fades out slowly, like theres a transition on it, meaning there is a slight delay in opening the menu. It's really annoying, because the phone is lightning quick, but then this happens, it's like the GPU can't cope with the transition/fade effect when you select the sub menu option.
I've turned all transition effects off in Nova Launcher to see if that's what was affecting it, but it's not. Is this meant to happen?
Thanks

In Settings -> Developer options, enable "force GPU rendering". It does increase graphics benchmarks by about 20%, and removes some of the UI sluggishness even with stock images. I'd also recommend you to use foxhound beta 0.1 of 4.0.4 android along with leankernel - no delays whatsoever
YEah this kinda bothers me too. Seems like Android can't really handle serveral 2D transitions at the same time...
I really hate the fact that the Android team at Google doesn't an eye for the small details, which are a big deal. This little transition in the settings meny gives away a huuge part of the experience. Some may say im overreacting, but hey just my thoughts..

I could not concur with this more. ICS is nice, but it is VERY unpolished. There are little annoying bugs/quirks everywhere and, while I know early adopters tend to pay the price for doing so, all these little issues are mostly unacceptable for a 4.0-level release on a flagship device.

You can definitely tell they're moving in this direction with the changes from 2.3 to 4.0 though. They're clearly trying to push towards a cleaner, thought-out experience across the device. Its just going to take some time for the old habits to die.
I truly think its just something google could fix in an update to the settings activities. Hopefully google doesnt ignore it though. The hardware is easily capable.

your first advice is completely pointless imho. That option is there to force third party apps that don't explicitly ask for 2d acceleration. All of the ics menus and all google apps already use gpu acceleration.
I think the problem is with the gpu. Menus and nav button transitions are MUCH smoother on my HP touchpad running cm9.
I agree with trying out 4.0.4 though. People say it's much improved in this regard. Paul's 4.0.4 is very popular.

Thank you for this. My phone feels much faster now.
Hi everyone,
I have my GSM Galaxy Nexus for nearly 2 months, and I'm really pleased with this phone, which replace my old yet good Galaxy S. The device is snappy, smooth, I can play every games and watch nearly every movie files I want etc, perfect for me, especially with its huge wide screen.
That said, I always try to find a little thing to reproach to my phone. Not so easy, but even so, I find something which can be a bit annoying.
We all use our launcher a lot, obviously, it is like the core/bridge app of our Android device. I noticed that the 4.0 launcher has some performances problems, let me explain you how to easily reproduce them (close all your apps in order to have the best performance as possible) :
-The transition between the app-drawer and the desktop panels can be not so smooth as it should with such a powerful device. Try to go in and out the app-drawer, you will notice that sometimes it lag, sometimes not. I asked myself why it behave like that, and I may have found the problem. When you enter in the app-drawer or when you flip your panels on the desktop or in the app-drawer, you surely have notice this little blue bar at the bottom at the screen, which indicate you where you are. If you try to go in/out the app-drawer while this bar is on the screen, the transition will be laggy. Just wait it disappear, and it will be smooth (if not, do it 2-3 more time, and it should be good).
-When you clicked on a widget in the app-drawer, a message will pop out about how to add it to your homescreen blablabla. It also notice that if you try to flip your panel in the appdrawer or the desktop while the message is on the screen, everything will be laggy, especially in the app-drawer, it will have horrible performance, but as soon as this message disappear, everything become smooth like before.
Why ? It don't know. At first, I thought the problem comes from the launcher, but maybe not. Indeed, if messages like the one I talked about above appear anywhere while you're using your device, like in the Web Browser for example, it will lag, maybe less than in the launcher, but it will.
So what ? Maybe the launcher is not fully hardware accelerated, or it lack optimizations ? It may be the case, but I try to run CM9 on my old Galaxy S, and it doesn't have such problems (the performance will depend on the old hardware itself), it is also the same on a friend's Galaxy SII, its launcher is butter-smooth even if you do want I explain.
Is the OMAP4460 or the PowerVR SGX540 too bad to run it correctly ? I doubt it is the case, since my 2 years old Galaxy S run it good. Indeed, even if I overclocked my device to 1400MHz with the "performance" governor, only the 1st case problem will be partially solved, the 2nd one will still make your device run like crap.
Since those lags can appear everywhere if above conditions are met, the problem may be that our phone can't run correctly if there are 2 "layers" on the screen, the message on foreground and your launcher on background for example. It is probably the case, and even if I study IT, I can't explain it really well, sorry
I obviously try a lot of ROMS : Stock 4.0.2/3/4, AOKP, CM9, ARHD, with stock and custom kernels, and they all have the same problem. If you want to have better performance, try to put the minimal CPU frequence to 700MHz, you will maybe lose 30 minutes of battery, but it is globally more usable if you want my opinion.
Do you experiment the same problems ? Have you any ideas about how to solve them ? Thanks to read me !
PS : The Galaxy Nexus also has performances problems if you are using it in landscape position. Everything will be less smooth and snappy. The best example is if you use the app-drawer, it back absolutely unusable.
Since upgrading to nova launcher prime my UI is very fluid. Landscape is still choppy but less so.
bow chicka wow wow.
I forgot to say that I also tried Nova and Apex, it has the same problems
