[Q] Why is text scrolling so bad on G2/DZ? - G2 and Desire Z Q&A, Help & Troubleshooting

I've recently got hold of a desire Z, which is great.
Something that puzzles me though is why the scrolling, particularly text lists or large sections of text in the browser is so choppy?
The GPU in the desire Z is supposed to be much better than that in My Nexus 1, and indeed stuff like home screen scrolling is much smother on the DZ than on the N1.
However, weirdly, text scrolling is much smoother on the N1.
It doesn't seem to matter which rom I use either (tried a few, stock, virtuous, CM7).

800mhz.. overclock to 1.5 than report back.

Overclocking helps of course, but it's still not quite as smooth as the N1, even at 1.5GHz.
What seems odd to me is how the home screen is way smoother on the DZ, but text scrolling is worse.
Maybe it's something to do with the optimization of the adreno 205 vs the 200, or maybe it's a driver issue?

Android isn't gpu accelerated.

Smooth scrolling a la iPhone?

I love my Desire and I cannot envisage swapping it for any other phone (except maybe a similar model with a keyboard!). It's obviously one of, if not THE best phone around at the moment.
The only thing I'm slightly envious of is the smooth scrolling of the iPhone. When I scroll through my "All programs" screen it's ever so slightly choppy. Same if I scroll through a long text message conversation. Hardly noticeable unless you put it next to an iPhone.
My question is this: since the Desire has so much horsepower, is it possible to optimise the interface so it's perfectly smooth like iPhone? I don't know anything about development, and suspect this is something that could only be changed by the Android designers, but is there any way a talented dev could do this in a ROM? Anyone care to explain to me yes/no, and why?
Thanks!
I tried out home++ beta yesterday, unfortunately it's not optimised for the desire yet (lots of icons missing) but the app list is silky smooth. I think its poor implementation on gooogle/htc's part rather than the phone being at fault.
Also I'm using handcent for text messaging, its smooth aswell, didnt notice any problems with stock messages app though.
I noticed the choppy scrolling on older Android phones, but I have not had that issue with the Desire yet. It's as smooth scrolling as possible. Even when I put my Desire next to an iPhone 3gs it is fast and smooth. The Desire is even a bit more responsive then the iPhone, which is very noticeable when typing.

I would say my Desire is definitely fast, but not so smooth. When lists scroll or things open and close on the iPhone it is a definite, measured type of action - it happens at consistent speed from the beginning to the end of the action/animation. No jerking or choppyness at ALL. Whereas on my Desire, despite it's 1gig processor, it doesn't achieve that same effect in all places.
I don't know how else to describe it. It's one of the only places Desire falls down compared to iPhone (oh, apart from the lousy video playback, poor camera recording framerate, cheap touchscreen and poor screen performance in sunlight!).

I noticed that too.
Menu scrolling isn't what i'd call choppy but it's just not AS smooth as the iPhone. This is especially apparent near the end of any menu for some reason.
An example of perfect scrolling speed on the Desire would be the settings menu. That is perfect, no choppiness, no lag, just perfect. Things like the app drawer and sometimes even the homescreens appear to drop a few frames from time to time.
I agree with you, is not smooth like iphone, even being faster than it. Maybe google needs to improve the ui of android to optimize it.

I think it's rather HTC's fault, cause in the stock Android apps everything is perfectly smooth here. Only the HTC apps sometimes stutter while scrolling.
I'm on an htc hero and notice the same thing. This is something htc needs to release a fix for

Check the clock when you scroll back to it - if an earlier time you see it for a microsecond when you scroll
yeah its definitely not anywhere as smooth as the iphone, scrolling through most lists is incredibly choppy, even my years old 1st generation ipod touch is silky smooth (even when scrolling through a list of albums with album artwork on each one)
but as someone has said, it seems to be only htc stuff thats like this (the messages app, the app drawer) other areas such as the settings scroll smoothly.
Not anywhere as smooth? Come on, don't exaggerate. It's almost the same as the iPhone, actually.
If you've ever used a Windows Mobile phone, you know what "not anywhere as smooth" means!
But still, of course, any improvement is welcomed...

LMAO!!!!

yeah, but using live wallpapers will definitely slowdown the scrolling in the homescreen. It's not much, but noticable. Without using live wallpapers, the scrolling is as smooth as it should be.
iphone scrolls page to page, of course this is smoother. Iphone can't handle scrolling over the entire page/apps.
And an Iphone is a dump of icons, doesnt sound like a smartphone to me
Remember the iPhone screen resolution is only 480x320 as well, significantly less than the Desire. Much less screen estate to move around.
Yep, +1
I mainly see this when scrolling to the bottom of the All Program menu.
There are others with this too:
URL blocked by XDA - Search for "lag program menu htc desire" another post in XDA by other users
I emailed HTC about the small amount of lag but they said to return my phone for an exchange! Slightly unnecessary.
Hopefully more people post their lag issues here, HTC see it and do something about it for their 2.2 release.
I've tried various things to try and resolve - made sure no other programs are running, no live wallpapers, no wallpaper at all
Its not a massive problem, but there is no noticeable lag in the stock 2.1 Android Apps drawer - so we know it shouldnt be an issue.
It does stutter a bit done it on all android phones i had from htc, if you use Helixlauncher 2 though that has a much nicer scroll menu and its as smooth as butter, i would love if they could add this style into the Sense system as it looks far better.
iPhone sucks man, if you like it why don't you buy one and you'll have your A LA iPhone smooth scrolling... Jeez, i don't understand soome people.... You have a Desire and still wanting an iPhone... SUCKS!
Using MCR (Modaco Custom Rom) here, without SenseUI. Then decided to install ADWLauncher, and to be honest the scrolling on the main screen/app drawer is super smooth now. So I'd say that this probably is HTC's 'bad' programming on the SenseUI.

that looks cool, I think SensUI is starting to get useless since google implemented many Sense-features into standard android too. The only thing that keeps me having SenseUI is the HTC-clock. I don't like the standard Android-clock widgets. Other than that, I think Sense is starting to get more and more useless. Last year, with android 1.5, Sense was pretty usable.

Laggy/Choppy scrolling?

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?

[MOD]Webkit browser accelerate

I didn't make this, I just found it and put it in a flashable zip.
It was in the meXdroid Pre-Ghost Chili ROM, but for some reason not in the latest AIO version. I think it was also in the CM7 nightlies, but I'm not entirely sure.
Anyway, it just makes the webkit browsers(pretty much all browsers except Opera and Firefox) a little smoother, especially when pinch-zooming in.
I tested this working on CM7 nightly 204 and meXdroid Ghost Chili AIO.
It didn't work on MIUI and Sense ROMS. MIUI hanged at boot and Sense crashed the browser. You can try it if you want though.
Download:
http://www.multiupload.com/P4UCPVX4IY
The .zip flashes 2 files:
system/lib/libwebcore.so
system/lib/libwebkitaccel.so
Do you have some benchmarks or something?
Because I don't know if I will flash it if it is a "little smoother"
Here's a video: http://www.youtube.com/watch?v=2DZnie3u0YI
Dang! That's smoother than Opera! Wish it was working for MIUI though :/
Sent from my HTC Vision using XDA App
It's not smoother than Opera, but it's definitely an improvement.
Zooming out is still a little laggy like normal, and scrolling on large pages(like xda forums expanded view) is still laggy.
I wonder why they removed this from the CM7 nightlys though.
When I first judged the performance, I was basing my observations on the YT video. Now, I'm running CM7 and using the stock browser.
- the stock browser seemed smoother than Dolphin HD, but yes, not as smooth as Opera. Rendering wasn't perfect on Opera 100% of the time though (the google mobile page comes to mind).
- it was definitely smoother than normal, mostly after the page finished loading. When the page was still loading, scrolling was still fairly choppy. But still definitely recommended for those not on Opera.

Definitely some difference on CM7. Stability is noticeably lower though.
Still not at Opera's level =/

I use stock browser on meXdroidmod ghost chili AIO. It is buttery smooth. Way better than the video posted above. I really can't imagine it being better cause its that smooth.
Sent from my HTC Vision using xda premium
I actually used meXdroidmod AIO in the video. After I flashed gapps(non modded) it broke the theme.
Also, because all browsers on Android use the same webkit engine, I doubt one is smoother than the other. Because of this, this should work on all those browsers(incl. Dolphin HD).
With the exception of Opera Mobile and Firefox though. Those 2 use their own rendering engine.

I haven't noticed any stability issues myself though, but I also rather have a occasional crash than the normal choppy browsing. I always had to use Opera, since the stock browsers were so horribly slow.
Let's hope IceCreamSandwich will be better. The ICS browser will supposedly have full hardware acceleration in the browser.
Also, I just tested this on my sisters' Nexus S, and it worked. Perhaps it works on more devices?

Yeah, it should work for any phone with 2.3.4 and above. The latest CM Nightlies build 220 has a performance option to smooth scrolling in general. Combine with this and its pretty darn smooth. Opera is a great alternative but its rendering can be screwy sometimes. Plus, it always opens pages in overview which drives me nuts, lol! But ICS, we are ALL looking forward to. I was unaware that the browser would have full hardware acceleration. That's awesome! Our devices have a decent GPU and great CPU so we should be set!
Thanks for the mod, it works well on the CM7 nightly build that I'm running

No, it also works on a Nexus S and probably more devices. But I'm not sure if the .zip will work on your device.
If it doesn't, you can just extract the zip and use adb to push "libwebkitaccel.so" and "libwebcore.so" to system/lib/.
Yep it works, snappy. Thanks dude

It causes some visual artifacts, so it's turned off.

I hate to admit it, but my Nexus is a little laggy

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.

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.

Launcher and global strange lags/low performance ?

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
